Oversold = can't tell for sure, there's no way of getting info on oversales anywhere other than within each individual airline.

Potentially it's all zeros.

What's the flight/citypair/date?

I see flights zeroed out on EF all the time, though there is no way to know the reason, whether impending cancellation, IRROPS, overbooking etc.

An oversale doesn't occur until the first VDB voucher is handed out, however ;)

Moved to the proper forum, and proper thread. /Moderator

As mentioned above, you can't tell if it's overbooked just from GDS availability. A friend and I had a recent AS flight show F0 Y1 before disappearing, but when we asked a friend with access to AS load factors, he said it was booked exactly to capacity with no overbooking. (AS per their official policy will tell you if the flight is overbooked if you call them, but it was easier to email the friend. ;)) The amount of overbooking authorized varies by route, time, and and (of course) airline.

Thanks guys! I am already checked-in to this particular flight(tomorrow). Upgrade has not been confirmed. Asked to be put on the airport upgrade list.

It seems that I consistently have issues with transcon redeyes leaving from the west coast once it is after midnight EDT. Normally, I cannot get flight availability information for a particular route anymore because the date/time are in the past from the east coast perspective. Is this a known issue?

Departure date/times are based on where the departing airport is, not where our servers are. If the information is no longer available it is because the airline is no longer making it available.

For example, it is now after midnight EDT (6/22) and you can still easily pull up information about flights that haven't yet departed tonight on the west coast for 6/21:

Okay, I just checked and apparently it happens at 1AM EDT. When searching for 6/21/2012 flights leaving at 12:00AM (default), just before and after 1AM EDT, the problem occurs.
Before 1AM: Shows all non-departed flights left that day (6/21). Everything seems fine.
After 1AM: Shows all flights for that day (6/21), including flights that have already departed (which, doesn't make any sense). Also, if I change the search time until 8PM, to only show the actual remaining flights of the day, it gives me a different list than the before 1AM search. In this example, the plane changed from showing as a 763 to a 757 and the departure time was skewed (DL 1406 LAX -> DTW), when the 763 is the correct plane. Also, the seat map is no longer available.

Anyway, this isn't uncommon behavior, and whacky things seems to happen at every 1AM EDT when the red-eye flights still haven't left yet! Thanks

The GDS we use is based in central time and 1pm Eastern is midnight central time, so the GDS is changing over then.

The error message for the seat map search comes directly from Delta. Since 1am EST represents 1 hour before departure, it could be under airport control at that time. Or, DLs host system just can't handle the time date difference at that point, either way it is nothing we have control over.

"Flight Cancelled"
 

I've not seen this before, but just now a flight search showed "Flight Cancelled" where the booking class availability usually goes. Did I just get lucky and catch a query just when AA updated its schedule, or do flights stay in the system for some period of time after being cancelled, or something else?

More oddly, the screen display shows "Flight Cancelled" but the "Share -> BBCode" shows it as x7 in all buckets (even P, which the other flights don't show).

In my case, I'm often interested in a good price on an I class fare on AA or BA, e.g., there are occasionally quite good prices on these but other times they're very high. I haven't found any site that will let me set an alert for an I fare from xxx-yyy that's under what's now available. Tons of sites are happy to alert me when a cheaper Q fare becomes available, but that's not what I'm looking for. (Even better would be a way to search broadly, such as "any business class fare from LAX OR SAN OR SFO to LHR OR BRU OR MAD" but I'm not holding much hope of that.)

Exactly!!!

I use this a lot when searching for good I fares and my dates are flexible. It's very handy.

Cool, I'll have to play with this.

Lately when searching flight availability for DL, I'm seeing tons of low fare inventory (E9, T9, U9, L9, ETC), but then a search on DL or Matrix gives back only higher inventory such as K, M, Q, etc. Is this an error or glitch, or can it be explained?

Using a specific example, I was checking availability on my SFO-MSP flight this Monday morning (DL1106), and it shows all classes with 9+ seats. When searching on Matrix or DL.com, it only shows M class.

Did you check to see if a fare is published for the appropriate class using the Fare Info tool?

The only fare showing is M+ (when validating fares). Does this mean anything?

Could it be that those fares are available, but only with certain routing? For example a SFO-MSP-MCI might be bookable with T class fares, but not SFO-MSP?

The reason you can't find the T (or other bottom-level) fares is because they aren't available now. Yes, there's inventory available, but those fares have some sort of restriction. An example of a restriction is advance purchase (the fare has to be purchased X days ahead of time).

Any thoughts or info on these two related issues? (1) EF showing "Flight Cancelled," and (2) EF's "share" copying flight status as wide open when display shows it as cancelled?

The flight is canceled, the bug is in the Share Results function.

Please send all search issues and bug reports to [email protected] so we don't miss them, thanks.

Thanks. I'm curious why and for how long a cancelled flight shows up in search results?

Ok, thanks. This one you have now, though, right?

A flight will show as canceled if and for how long the airline marks it as such. The GDS usually still returns the flight in the availability search unless the airline removes it from the schedule for that day or the airline 0s out the classes, which AA didn't do here.

Ok, thanks. This one you have now, though, right?[/QUOTE]

Yes, thanks.

What is the code for Alaska Air coach award space? I was told in the Alaska forum that it was W. However, when I put that into an Expert Flyer search, it pulled up Choice award space, not Saver. I want to use Avios points and BA will only see award space at the Saver level.

Here is my query in the AS forum and the response to it.

W inventory is what you want to be looking for.

http://www.expertflyer.com/sessionlessClassList.do

However I searched on Expert Flyer for MRY-SAN on Oct 29 using code W. It showed availability - but it was Choice availability and not Saver. BA can only book Saver awards on AS.

This is embarrassing. Still, confession is good for the soul. I set up the alert for 1 seat but was searching for 2 seats. There IS one seat available. Thank you to the person who ever so gently pointed this out to me by PM.

How am I supposed to interpret a response when a particular bucket is missing altogether?

Example: Yesterday, I searched for Z, U, and C availability on an AA flight and it showed Z6 U2 C4. Today it shows Z6 C4, with no mention of U. A few other flights explicitly say U0 but in this case U is simply missing.

Should this be treated as "U0" or as "some bug, check later"?

U0. For the case where you see 2 U0 flights before your flight, as noted in the help for the Awards and Upgrade results page:

•Sometimes American will return just two flights where the requested award seat availability is zero on both flights, even when there are later non-stop/direct flights scheduled. This is American's way of indicating that none of the later flights have available inventory for the request class either.

To test, set the time of day to just before the departure time of the flight and it should show as U0. It is also possible that AA removed the class from the flight temporarily. Rare, but we've seen it happen.

Hi,
I'm considering subscribing to EF in order to book award domestic SAAver Flights on AA using BA Avios points. My understanding is that I will be searching SAAver flights on AA to accomplish this, and not BA on EF. How soon should I subscribe to EF in order to get award flights for August 2013? 330 days out - in September 2012? Thanks!

Yes your understanding is correct. You can subscribe to ExpertFlyer anytime! Yes, the flight will show 331 days before departure at which time you can search for awards and create Flight Alerts for flights that don't currently have award inventory available.

Android version coming soon...

While searching for fares, I find that sometimes there is a little mismatch between what I am looking for and what EF offers. Basically, EF asks for origin, destination, dates, etc and throws lots of fares at me. Sometimes that is what I want. Sometimes not, and I was just reminded of that, so let me illustrate.

I prefer AA/OW and usually fly from ORD, but I could fly from MKE and STL quite easily for a good deal. For sufficiently lucrative deals, even from NYC, DFW, or LAX. I would like go go somewhere in S/SE Asia. Depending on fares, let's say BKK, HKG, SIN, or DEL.

So this will translate into 24 queries.

Moreover, each query will throw a lot of fares at me, although I am only interested in the lowest few.

What I would like is a little more powerful syntax and a little more filtering. For example if I could state my itinerary ITA style,

From ORD,MKE,STL,NYC,DFW,LAX
To BKK,SIN,HKG,DEL
Restricted to AA,CX (can already do that)
All dates (can already do that)
And just give me the lowest few fares (I can provide the $ cutoff, or the number of fares to be displayed. Of course, I can easily ignore the expensive ones if a long list is returned, but I am imagining that it might save EF some money if it doesn't have to provide unnecessary info.)

You yourself mentioned ITA. That's the tool for doing what you lay out. EF is an awesome tool, but for other purposes. Like PowerPoint vs. Excel.

If ITA were sufficient, why would we be looking for fares at EF in the first place?

EF orders the results by base fares, which I find useful. Fare rules, routing rules, etc are available with one click. At ITA you'd need to build complete trips to see the rules.

Besides, I am talking about strengthening the capabilities of EF which is a paid service. ITA is a freebie which can be taken away anytime.

The only reason I mentioned ITA was to illustrate a syntax that, eg, allows you to ask about fares from 6 origins to 4 destinations through 3 possible connections, all in one query. At EF this would take 72 queries.

Therein lies the problem. Even if they automated it for you, EF would still be doing 72 queries on the back-end, and at a few cents per query, your search costs them upwards of a buck or more. Not too many of those and you become a not-very-profitable customer for them. :)

EF and ITA are built completely differently on the back end. ITA has access to raw fare data and uses a powerful algorithm to determine the best prices and routings available. EF does not have access to raw fare data (that costs several hundred thousand dollars per year, maybe more, as I recall) and only receives what the GDS spits out when it is queried.

Don't get me wrong, I would love it if EF could do what ITA does, but it's simply not feasible.

OK, I understand. In my case, if I am looking for a great fare to Asia from somewhere in the USA, I'd end up doing dozens of queries anyway, one at a time, until I see something. Unless I get lucky and someone posts it at FT/MP. Still, I can see how others will abuse the feature. :)

So, a poor man's version of what I wanted would be for EF to cache results from various queries and have a list of cheapest fares that have been found, in broad categories like domestic transcon, NA to Asia, NA to Europe, Europe to Asia, NA to SA, etc. Or run their own scan at some regular interval (once a day, once a week, whatever is affordable) and posts the cheapest fares found. No guarantee that the fare is still alive when I am looking at the list, but if it interests me I'll make a live query.

This could even save EF some money, as many repetitious queries now being made by different customers would be reduced.

I don't understand why you wouldn't use ITA for this (unchecking "Only show flights and prices with available seats" if all you're looking for is the lowest PUBLISHED fare, not one that's available).

What am I missing?

First, ITA requires you to have an idea of the dates you'd be traveling; I just want to know what are the best fares filed.

Second, you have to choose round trip v multi-city before knowing which fares allow stopovers and which don't.

Third, ITA sorts by total price, EF by base fares; each has its utility.

Fourth, EF already provides all the info I want, but requires a few dozen queries. I have the reasonable desire to explore if this can be made a tad more efficient.

Most importantly, this is the kind of info many EF customers would be interested in: finding out fares and fare/routing/stopover rules before choosing dates and itinerary, instead of making a blind choice and checking availability.

I'd like to see if EF's user interface can be aligned with those needs.

I can certainly understand if this is not affordable. Not knowing their business details, I had no idea, but I do understand that everyone has their budget and bills.

However, the argument that something sort of similar though not quite the same is available at some free site elsewhere, which may have been in the process of diluting public access, makes no sense.

The back-end processes to get what you are looking for are completely different. EF queries the GDSes in real-time. They don't have access to raw fare data. To know the best fares filed, you either need access to the raw fare data as mentioned previously or you'd need to do many hundreds of queries to the GDS. It is not feasible to program EF to do this--it's not just a matter of automating some tasks, it's like asking a motorscooter to do the work of an 18-wheeler. They're two completely different things.

What you're looking for is what was formerly supplied by FareCompare.com before they shut it down (for whatever reason). That was one of my go-to sites, and there really isn't anything out there to replace it and likely won't be, given the cost to obtain the data.

The "Show Fares for All Travel Dates" option will allow you to see all published fares regardless of date, however a city pair is still required due to GDS limitations.

Does EF allow me to search for award space on all 3 of the alliances? When I do a search, will it pull up all alliance members who have space, or do I have to search by airline and route.

I've got a lot of miles I intend on using over the next couple of months/years. most of them are in United. I intend to be traveling to Africa and Europe primarily. A trip to South America on AA miles is also in the future
