The crowdsourcing used in this thread to identify 4 SuperJ aircraft (see wiki) with wifi appears to have been successful, BA have confirmed that only 4 aircraft have operating wifi at the moment. However they have told Trade and Speedbird:

Interesting that it is Visa rather than American Express

That's good to hear. I won't be on BA until next few years or so. I was hoped if they will installed wifi on the entire 747-400 or 777 aircraft, as well as short-haul flight.

I would think by the time you next fly BA the chances are that the roll out will be complete. If I remember correctly, BA intends to have 90% of its fleet kitted out with WiFi.

Oh, I see.

Just wondered why every Emirates A380 has Wi-fi, but they use SITA which has been available to install since 2011....

Completely free to FF members and 2 hours free to non status passengers. No talk of a "sponsor".

Any WiFi is better than nothing right now, but some wifi is nearly unusable. For instance, SQ A380 one is incredibly slow, prone to drop-put and the maximum plan you can get for the flight is 50MB, which you would soon use up if you are trying to send a large-ish attachment to your email and it keeps dropping out and it has to start again. I had to buy two lots of 50MB on a flight, and it felt a bit annoying paying something like USD 40 (USD 20 x 2, from memory) after paying £8k for the trip although I got over it. It's the OnAir system from memory.

Anyway, it took nearly an hour to send a 20MB attachment (that's when it didn't drop out part-way) due to its slow speed. It wasn't an exception as that's pretty normal on the SQ A380. On the other hand their newer system on their A350 is far superior, much faster, and it's a timed flat rate, and isn't so prone to drop-out (basically, thankfully that is also the case on their 77W). This one I think is Panasonic.

In my experience though their A380 had less downtime (but lots and lots of drop-outs) than their A350/77W.

Then I recently used the wifi on LX on their 77W. The speed is about the same as the SQ A350/77W, but the pricing was pretty steep, at 50MB for CHF 19 I think, up to 120MB for CHF 59 (smaller plans are available). Quite a bit of downtime also.

Both LX and SQ ones are payable regardless of the cabin.

On the other hand JL one is timed rather than based on MB, and free for the whole flight for F passengers, and the speed seems to be similar to SQ A350/77W and LX 77W. (JL also have free wifi on their wifi-equipped domestic fleet.). I haven't noticed much downtime but this was mainly for a different route so it's not really fair to compare the downtime with others.

From what I gather (in fact based on the speed reported by users it is probably a fact rather than my guess), BA's is faster than any of those, and the pricing seems to be pretty sensible, so I hope it's a good, reliable one when it eventually gets installed on non-747s. Sadly no 747s on the routes I fly, so I am currently having to fly other carriers on longer journeys.

I haven't yet come across a wifi I would consider any way fast, however the ones I have used are good enough for most emailing and social media.

This can be a real blessing....arriving after a long haul flight and you don't have a mailbox of dozens of .messages to trawl through. The prices vary dramatically too.

Let's face it though, BA are behind the curve on this, and with normal BA roll out speeds (as seen by bedding, CW food etc) it ain't going to happen any time soon.

It could make for an interesting thread though - tracking roll out of food, bedding, wifi - anyone who gets all three can shout 'house'. If you travel from LGW on the other hand I predict that you can safely log out until at least 2020. Those 777s are going for densification, an ideal time to install wifi at the same time.

One of my pet annoyances is the ever ballooning size of attachments, the King James Bible can be sent as a 1.4 mb ePub file (and it has a few maps in it), so nothing should be bigger than that. There again my current email account is 33 years old and can still work with its original PDP-10 address, beginning with the number 7. And in those days concision was a necessity.

Believe it or not this stupid file was originally around 250MB when it was sent to me (not by email, might I add, and I did not downloaded it on-board!) because of a big pile of high resolution photos, which they did not even need to send to me, scattered around approx. 100 slides of PowerPoint junk that were supposed to be part of a 30 min presentation. Hmmm, I have no idea how that was supposed to work. Anyway, I trashed most of it before sending it back to them but unfortunately they wished to retain a large chunk of the junk, hence 20MB. I was rather aggravated by the whole thing already when the wifi (actually not the wifi, it was the satellite connection) kept dropping out.

The internet should eat that kind of digital junk, really. Maybe that's what the SQ A380 wifi was doing. Protest against digital junk (especially death-by-PowerPoint).

Regardless though, even some purely text-based emails were very slow to download/send, so it was functional but not really good for the waste-of-bandwidth modern day files.

Hopefully BA wifi, when it eventually reaches me, will not be so slow as to add to my aggravation like this.

It's not cutting edge, but it requires cutting a pressure vessel.

The job I believe is done in CWL (don't know about the 380s) so it's a bit of an issue for the 78s since trucking them on the M4 is not that convenient!

Well I suppose BA could 'self sponsor' too. Particularly for BAEC status members.

And every Emirates A380 I've been on has had terrible Wifi. Better to get something decent rather than something that may or may not allow you to download your emails once or twice a flight.

And the EK 'free' Wifi is limited 20MB, so not a great deal these days. Also, it seems that Silvers don't get the full free package anymore when in Y (or at least my missus didn't last week).

EK's wifi is woeful
QR/EY not too bad
AA generally excellent. Just book your next trans-at as BA 15xx and bring your laptop!

Silvers don't get free wifi in Y any more on EK. Discounted rates - 150mb for 4.99 I believe.

For many people 20mb is enough for whatsapp etc.

Still it's better than the wifi on BA A380s, eh ;)
