All Nippon Airways Mileage Club - All Nippon Airways NH1006 Bad Experience

Hi everyone,

I was just curious if anyone has experienced this kind of thing like I did on an All Nippon Airways flight.

About two/three hours into the flight, the aircraft, a 777-200ER, began to get very warm inside and very uncomfortable.
My father and a fellow passenger went to talk to the flight attendants along with another passenger to complain, but they refused to lower the temperatures due to the "majority" of passengers being Japanese and that they prefer warmer temperatures. Next thing I know, my ears are ringing, my vision goes white, I'm sweating all over, my mother touches my forehead and I'm cold!

She tried to have me get up.. then I pass out. Next thing I know I'm laying across three rows of seats and I find out there's about four or five other people laying around the plane on the floor because of a similar issue. This was a horrifying incident that I've never experienced before on any flight. This was a very unfortunate incident that could have been resolved very easily. One can easily bundle up if the temperature aboard a plane is cool; however, if the temperature is very warm, what am I supposed to do? Cold water wasn't enough. Their displays showed it was 83 degrees inside the plane. I have never experienced something like this and I've been to Japan over 20 times.

Before flying with ANA, I was hoping to enjoy the excellent customer service and care that they pride themselves for; however, after this incident, I am wondering if I should every fly with ANA again. I hope to visit Japan again next year and many years to come, but it might have to be with someone else.

Has anyone experienced something similar? It seems pretty ridiculous that plane doesn't have air nozzles as well. This was apparent also on my flight going to Narita from SFO (777-300ER).

Thanks.

83F is warm , but it is not exactly the same as a tropical heatwave. I'd see a doctor if I were you. It is not normal to pass out at a temperature like that.

Never heard of this before on any airplane, except once when I was stuck on the tarmac with the engines not running to save fuel (No running engines = no AC) and the APU wasn't operating.

But yeah... See a doctor, that's not normal. Perhaps you have an acute case of claustrophobia as well?? :confused:

I haven't taken an ana flight for a long time but I can confirm that another japanese airline *cough* JAL *cough* does exactly the same thing on several of it's flights.
They set their cabin temperature at 28C "because Japanese are sensitive to cold"
Funny but I thought that 28C was on the hot side of things, considering that the Japanese government asked people to conserve power and set their air conditioning to 28C or higher during the summer months (which implies making a sacrifice of being less comfortable)

AA also does this sometimes on JFK NRT flights. I have seen the temperature at 86 degrees before.
(And felt it too!)
4 beers and I still felt thirsty.

If you want hot..try riding a Japanese train (Limited Expess type)in winter. You would swear someone had lit an old fashioned wood or coal stove right beside you. Little rough on the system when you stand on the platform in winter all bundled up and then step into what ends up feeling like a dry sauna.

How do Japanese people adapt to this?

It is something strange that the cabin temp was such high.... but probable.
Compared with south east asian airlines like TG (Thai Airways Intl) and SQ (Singapore airllines), aircon at NH is very much milder - while TG/SQ offer ridiculously strong aircon.
I sometimes need a few blankets even though I already wear jakcket, sweater + muffler.

As NH cabin attendants mentioned, Jp people dont have enough aircon fastness.
Next time you board NH, wear as little as possible... tunktop/shorts + sandle... ?

I did an ORD-NRT roundtrip on NH last month and found it unusually warm. However, it was not so uncomfortable as to result in passing out.

This is a common complaint on NH, but having personally flown in Y, C and F cabins TPAC, intra Asia, domestic, etc several times, I've never found the environment to be too warm. And I'm usually pretty sensitive to that as well, keeping the AC cranking around the clock at home and in the office.

Passing out is a major problem. I'd contact the airline directly if there were literal medical / safety issues as a result of anything on the flight.

How do Japanese people adapt to this?

They just grow up that way. Sometimes Japan feels like it's in the tropics.

I always have trouble in Japan in summer. I was there this past July and I went through about three changes of clothes per day. It's HOT. And humid. I'm from New York and we do not have comparable weather in the summer, even as hot as it gets here.

Sometimes their lack of air conditioning use annoys me as well, because they have it and often don't use it. I know this past summer they were conserving energy, but it's not just this year that it's been like that. It's always like that. They really are just used to it being hot in summer and cold in winter. Also, the traditional methods they use of heating houses in the winter are not that effective so some people see it as a relief when it starts to get hot out (which means it's not so cold at night anymore, which it can still be in spring or fall).

They even have special cars on the trains that use less air conditioning than normal. Some people prefer that. Few people seem to actually avoid these cars, that I've noticed.

Both ANA and JAL keep their planes warm, but I can't imagine passing out at 83F. You'd never make it through your first hour off the plane in Japan during summer if you can't deal with 83.

How do Japanese people adapt to this?

That's just the way it is.

You could ask a similar question about how people put up with cold in a cold weather climate..for example, how could my kids wait for a school bus at minus 40C...but they did (think Northern Alberta). Hot and cold is more related to what you are used to and acclimatized to than anything else.

Japan does seems to use heat much more in winter than air conditioning in summer.

I've noted this on a number of different Asian airlines. I find it absolutely miserable, it really bothers me allot. More so on a plane than it would anywhere else. Especially crammed in Y because it dramatically amplifies any claustrophobic feelings you may have.

A cold cabin makes you want to cuddle up under your blanket. It makes the lack of space seem "cozy". A hot cabin plus cramped Y seating is just plain miserable. Almost unbearable at times.

I imagine the OP suffered a panic attack and lost consciousness due to hyperventilating. I sympathize.

How do Japanese people adapt to this?

I guess they are just used to it. Trains and shops seem to be heated even hotter the further north you go, making the temperature difference even greater; despite this, Japanese don't tend to even take off their outer layers when boarding trains or entering shops and remain dressed for the cold outside temperatures. I don't know how they don't just melt.

I too find ANA's 'planes incredibly hot and generally change into short-sleeves and shorts on board; even then I wake up with a sweaty blanket - it's truly lovely. If you're travelling in Y and the heat bothers you - try to get the exit row seats near the doors, as it is a bit colder there.

I have a Casio Digital Wrist Watch with temperature reading on it! So there is little question as to what the temp is. Any temp over 80 degrees F is HOT! And below 72 degrees is cold in an airplane because the HUMIDITY is very low from the air-conditioning removing the moisture from the air. More so at high altitudes.
With the LOW humidity and hot temperatures, the absorption of oxygen and discharge of carbon dioxide decreases in the dry lung tissues.

The Captains are obviously flying with the high temperatures in the passenger cabin to reduce the burning of fuel on the air conditioning to lower the temp enough to be HEALTHY and comfortable for the passengers and the cabin staff. Fortunately, for us, the Captain & Pilots are kept more comfortable with separate temperature controls in the Flight Deck. I would hate for them to pass out, but it could happen! Isn't 75-78 degrees the recommended comfort levels with normal humidity?

On several occasions with breathing difficulties, I have asked the FA to tell the Captain, when the temp approaches 80 degrees F or starts dropping to 72 degrees F showing the temp on the watch for emphasis. One FA said that she didn't know about those things and refused to tell the Captain. Low humidity also makes the skin dry and 'feel' colder!

I do hear the Japanese complains the temperature in North American flights are cold... I do feel that way as well... I fly UA mainly and bring extra jacket because I usually feel cold on their plane.

Next time, try US airlines or wear layers so that you can take a couple if it gets too hot. I hope you feel better now.

Most North American flights are kept at NORMAL temperature around 74-78 degrees F. :)
Better for oxygen absorption in the lungs. Often it is cooler in the front cabins and hotter as you go toward the rear cabins.
It is the LOW humidity, that gives the sensation of being COLDER then NORMAL on the dry skin! mad:

But I am stunned, that flights are kept at 83 degrees F with the unhealthy consequences, and I will not fly those airlines. It must be difficult for people with Chronic Obstructive Pulmonary Disease, who are already compromised with insufficient oxygen absorption.
The Flight Crew must be over riding some official regulations putting the temp up that high! :td:

The above is true for people who keep their house/apt at a higher temperature, especially in the Winter, when the heated air gets dry. When you heat up COLD air, the moisture/humidity drops to dry levels. Air conditioning in the Summer does the same thing! :rolleyes:

Just as a PP stated, when it's cold you can always put on more layers, but when it's hot you can only take off so much.

I don't care what the Japanese sensibility is of the matter. To jack up the interior temperature of a cabin no one can leave for 10+ hours is simply piss-poor customer service standards. However, I have never had this problem onboard an ANA flight. My only complaint comes when I'm seated near someone who is morbidly obese and has a radial span of human warmth which exceeds a celestial supernova. Now, that makes me sweat. But (and I realize I sound like a snob on this), I only fly F, so if it is too warm it's just another reason for me to order cool, comped beverages and ice cream.

I just flew on ANA this week on two different flights and I didnt have any heat issues. I only had a t-shirt on though and I had to use the blanket.

I did have a complain about their train - way too crowded and hot and also the seats are heated. On a 50 minute trip on the Seibu Shinjuku line, my ar_se got cooked so I had to get up and stand for 25 minutes..

The Captains are obviously flying with the high temperatures in the passenger cabin to reduce the burning of fuel on the air conditioning to lower the temp enough

There is no cooling going on; the outside temp at cruising altitude is around -40 C.

I do feel their cabins are on the warm side, but if most people prefer it that way, who am I to demand that everyone else have to put up with the colder temps? Next time you are on a flt, look around. Many Japanese use the blanket in addition to their substantial clothing.

Indeed. I was in Y LHR-NRT a few weeks ago, I was warm but not hot in a t-shirt despite sitting in the exit row next by the door. The chap next to me was wearing a jumper and coat under his blanket (and also never left his seat in the whole flight).

It does tend to get warmer further back, and I'm sure it's tricky to balance different people's temperature preferences. As Beard Papa said there is a limit to how much clothing you can take off for personal thermo-regulation, versus unlimited extra layers/blankets for warmth. I have finally won the battle of the thermostat at work (now down to 25C), so I'm no longer suffering from dehydration - however, this has led to some people wearing blankets and shawls at their desk.

There is no cooling going on; the outside temp at cruising altitude is around -40 C.

Yes, but the outside air is at extremely low pressure. The air that is used to pressurize the cabin is bleed air tapped from various stages of the engine compressor turbines. This air is as hot as an oven (200-250 deg C) and absolutely requires cooling before entering the cabin.

Just as a PP stated, when it's cold you can always put on more layers, but when it's hot you can only take off so much.


Exactly. And when bodies are so close together in a confined space, that adds to the heat. There are more health issues from overheating than being too cold - fainting, nausea, vertigo etc...........passing out can be more serious than it appears. It is a lot easier to warm up if you are cold in an aircraft cabin than the other way around.

Thanks everyone for their comments. It is nice to hear some feedback from many folks. Does anyone know why ANA doesn't have the air nozzles? Is it for better efficiency? ANA has been the only carrier I've been on that doesn't have those nozzles. Does anyone know if the 787 that will be coming to SJC may have the air nozzles or is this now a thing of the past?

Taking off more clothes is not an easy solution!
The real actiion takes place in the lungs with breathing HOT DRY AIR!
More so, when a person is NOT drinking enough CLEAR NON-ALCOHOLIC NON-CARBONATED FLUIDS on long flights! So don't forget to drink EXTRA bottled water or even low sugar juices, if you can find one of those.^

Pwei: The air conditioning works to cool off the hot air bleed from the engines for the cabin. I was on a plane delayed at Sao Paulo with air conditioning problems for one of two engines needing a sensor repair. The explanation was we would be flying over the Amazon, and it was too hot to chance it with one engine.:(
I was coming down with a severe sinus infection/flu while waiting several hours on board for the plane repair and didn't want to spend more time waiting on the plane or fly sick, so I asked the Continental Concierge still on board to see if I could get a seat on the same flight the next day, and find out if the Airport Marriott had availablity. She arranged both in a short period of time and insisted on getting a wheelchair to take me out to the street curb for the hotel shuttle to pick me up. Got to the hotel just in time for the ending of the Dinner Buffet and several bowls of chicken soup followed by a GQQD nights sleep. Repeated the soup treatment at the Lunch Buffet and was much better for the evening flight to Houston. :D

Glad all is ok for you now - it must have been an very unpleasant experience. From the pictures, it doesn't look like there will be nozzles on the 787 - but the climate control on these 'planes is supposed to be excellent - with much higher humidity and pressure than is possible on current aircraft. If this is the case, it should make a massive difference on comfort on long haul flights - even if ANA do keep them too hot.

ANA normally set up a box with drinks and cups in the galleys for PAX to take freely as well as give out bottles of water with the meal service which you can keep for later. I find myself having to take in a lot of fluids (which seems to amuse the cabin crew), but still feel dehydrated and I find this more noticeable on ANA flights. This of course has nothing to do with excessive alcohol intake ;)

How do Japanese people adapt to this?

Perhaps they are made that way.

Call it science.

It sure can make the rest of us uncomfortable, though!

Well most Asians in general like warmer weather indoors vs. North Americans, its problem in the offices (our office in Taiwan likes it at 25-26C) where locals like it warmer, and vistors in Asia often find it warmer than there used too, so I think it must hard for air crews to make everyone happy.

Their dry skin is their thermometer instead of knowing the air temperature and humidity. This is a wide open area for the Captain to explain to them the temperature is correct, but their sensation of warm, hot or cold is dependent on the low humidity. Of course, the Flight Attendents would do wonders on making passengers more comfortable by accepting a 'normal' range of temperature. This is nothing more then a little bit of high school physics. :rolleyes:

Hello all,

As someone seated up front at the controls on the Air Japan flights and in the back on the NH flights to/from ORD, I would like to add my two cents. The Japanese are indeed a cold people. (Not personality wise, just temp wise) I have been hot on several occasions when commuting back and forth to the states. When I am up front, I always try to keep the temp around the 24 C mark. Some of the Japanese captains I fly with will try to keep it up around 26 but I have never had one try to fly at 28 C. My suggestion is if you are hot, tell the FA and hopefully she will tell the people up front.

The air is coming from the bleed air system of the engines on all but the 787. So it cools the air it uses. However, I have never heard of obtaining fuel savings by flying at a warmer cabin temperature. It isn't on our flight plans anywhere so I wouldn't put too much faith into that argument. We can save fuel by flying slower, higher, or shorter distances but that is about it.

As always, thanks for your patronage. ^

Hey jrmyl:
Thanks for your contribution and thanks for keeping us safe!

Could the poor higher temp control settings be attributed to faulty mechical problems?

On the other hand are there higher temps 'unofficially' set higher for fuel savings in the past on older airplanes? 707's? Intercontinental flights?
I can recall announcements to that effect on several flights in the good 'ol' days! :(

Being colder then others at normal temperatures is a sign of LOW Metabolism/Thyroid Function. It can be common among people who eat similiar foods in their diet, which lowers thyroid function , that also decreases with age, as well. More common after the age of 25 years among women, and accounts for many other symptoms like weight gain, PMS, ! :(.

I've always thought the feeling of cold might be something to do with low body fat %. But in Japan what I can't reconcile is why workplaces, shops, and methods of transportation are so highly heated in winter, but Japanese homes tend to be kept barely above outside temperatures.

Thanks for correcting me.

Perhaps it has something to do with them having high heating expenses, and that they try to put up with it at home so as to save money.

Another note: I had a bad experience in the mini Y cabin of NH901 once a couple years back. It was cooler in the large Y cabin in the back. Now, I avoid that cabin. It usually fills up to the brim too. Not sure if it still applies to the retrofitted 767s, but I'm not inclined to find out the hard way.

Even the new 787's state they will have a better humidity level! ^

I have heard that features that would improve home heating drive up the tax assessment of a house significantly, so it's more economical to use thin walls and crappy AC units than to use thick walls and central heating. This is not the case in most larger buildings (where central HVAC is the only practical choice) or in vehicles.

That's interesting -- I'd always assumed this was just the generally craptastic nature of Japanese commodity house-building (e.g. 25 year design life). I count myself fortunate to have lived in buildings rather better built than average.

Unrelated to ANA, I was on a flight years ago from Karachi to BKK and the temp and the conditions made it hard to breathe. I felt like I was going to suffocate. I finally got up to advise the flight crew and walking to the galley noticed that ten or fifteen passengers were passed out. The crew had not noticed it as they were too busy gossiping. They called the cockpit (i think), the air circulation improved and the situation became normal.

Sometimes their lack of air conditioning use annoys me as well, because they have it and often don't use it.

Better than the American and Mexican habit of keeping malls and homes at sub-zero temperatures even when it's a nice temperate day outside.

I was on a NH 767 from NRT to TPE last week...and I remembered this thread as the cabin was incredibly stuffy with no discernible air flow.

I was using the safety card as a fan to flap some air around, and the sweet FA was nice enough to offer me a blanket :)

The air is nice and cold up there at 35,000 ft, even the bleed air off the engine once it depressurizes - so it doesn't cost them anything to keep the cabin at a reasonable temperature...but I guess hot-as-heck is reasonable for the Japanese. I couldn't imagine taking a long-haul flight in these conditions as much as I'm looking forward to the SEA/NRT service with the 787.

Come to think of it, the ANA Lounge at NRT wasn't exactly chilly either...and the shower rooms had little to no ventilation.

Thanks for the messages everyone!

I want to fly on a plane with air nozzles again as to avoid such a problem again.. I do live in San Jose and due to the 787 coming to San Jose eventually, are there nozzles on this plane? It appears there is something based on these pictures below. Has anyone been on a 787 and know one way or another?

I think one of the problems is removing the air nozzles. I increasingly find it harder to be cool and comfortable.

I assume the lack of nozzles is cost savings?

I'd like to retract all my complaining about hot ANA flights. Just back from my first ever transpac on an american carrier (UA) - it was freezing and I was shivering under my paper thin blanket. Combined with many many other reasons, I don't on repeating this experience - so will stick to the heat on ANA metal in future.

The air is nice and cold up there at 35,000 ft, even the bleed air off the engine once it depressurizes - so it doesn't cost them anything to keep the cabin at a reasonable temperature

Hmm, air pressure at a typical cabin altitude of 8,000 ft is about 75.3 kPa. At 35,000 ft, the outside air pressure is more like 23.8 kPa. Temperature outside according to the ISA is about -54 deg C or 219 deg K. So what's the temperature of the outside air compressed to the pressure of the inside air?

Gay-Lussac's law (the gas pressure law) tells us that P1/T1 = P2/T2.

So without the benefit of "air conditioning", the temperature inside would be 693 deg K or about 420 deg.

Heat-exchange to the outside air a lot of this, but you're still having to drive air-cycle machines to drop the rest of the way to get acceptable cabin temperatures; and that equates to fuel burn.

This is not where the cabin air comes from - cabin ventilation is bleed air off the cold (relative to the combustion section) compressor section, which is hot at pressurization, but is cooled as it gets run past heat exchangers and the pressure is dumped....and often this results in overly frigid air which needs to be warmed up before being piped into the cabin.

There you go, you said it yourself "the pressure is dumped". What do you think pressurized that air in the first place? The burning of fuel. Another way to say this is that some of the engine's power is used to pump the heat out of the bleed air. It's not like bleed-air is "free"; if it was, why would Boeing goes to such a lot of trouble to engineer an aircraft which replaced most of the bleed-air usage with electrical systems (the 787)?

Boeing's website concurs with NickW.

Individual nozzles are optional. Lufthansa wide-bodies too don't have individual air nozzles.

just carry shorts n tshirt... after seatbelt sign change to summer style!

My ANA 787 flight last week was very comfortable - not too warm, not too cold and they ordered the aircraft with passenger vents which helps customize the comfort level.

My first ANA flight actually using the blanket to keep warm instead of mopping up sweat :)

^^
It's great to have the vents and temperature was much better on my 787 flights too. Ended up needing an extra blanket - never before on ANA except to mop up the sweat. Just hoping new aircraft deliveries have better fitted cabins and don't rattle so much.

NH and JAL always have cabins that are waaaaay too hot for me. The temperature is set between 26 and 28 degrees. On the B777 the flight attendants can alter the temperature but they are very reluctant to do so because of the number of Japanese on board who all seem to be fickle regarding temperature.

Unfortunately they did not equip their aircraft with individual vents for air above the seats which can lower the temperature in your "personal" area. It has forced me to buy a plug in USB fan that clips on to the seat/area around me to make sure its comfortable for me to sleep on the flights to Europe.

You can also try sitting at an exit door. The area around there is significantly cooler.

Holy cow! I never knew ANA did this. I took a flight from TPE-NRT on NH but I didn't really feel the heat.

The women passengers who complain about the cold cabins., when set at normal temperatures, are usually HYPOTHYROID and not being treated approprioately by their Drs. This is a common complaint.

I hope the new 787 JAL flights from San Diego to Narita do not have that problem with the increased humidity!^

It was very hot last week when I flew NH 7 from NRT to SFO.
Most westerners wore shorts and tshirts but Japanese ppl wore so many layers of jacket including the cardigan!!!
