It is not something expected on our part, we can't speak to AA's IT intentions.

Is it possible to look up YQ by route on EF?

You can do a Fare Information search for a route and look up the YQ for the airline in the Fare Rules.

Just a quick thank you to the Expert Flyer team, and my subscription has again more than paid for itself.
I had a complicated CX booking from North America to Asia and back, with stops and open-jaw, all in discounted business class ( I class).
At time of booking, I class was not available on one of the flights ( a 5 hour flight) so I was booked and ticketed in W ( Premium Economy) for that leg.
I had set up an alert for I class, and a few days ago I received the email that it was available. But when I called the airline, they told me that it was still I0.
When I questioned the EF team, they explained to me that the I class availability was determined, and varied, by Point of Sale.
So I set up another alert with my Point of Sale. This morning I got another email alert that it was available.
When I called in to CX, they were able to make the change, and re-ticket me, with no charge other than additional $10 in taxes.
It will be a much nicer 5 hours in a flat bed rather than PE.
Thank you EF!.

EF newbie question.

I�m flying DEL-YVR-YOW on 2/28, booked in B, which is upgradable with P space on AC.

I was waitlisted on DEL-YVR (AC45) and cleared for YVR-YOW. I created a P space alert for AC45 and received an alert that P is now available (latest check says P=2).

But my waitlist didn�t clear so I called AC and they said they still see no P space in their system.

FWIW, if I check DEL-YVR-YOW in EF it indeed shows P=0 on AC45. But DEL-YVR on its own shows P=2. And AC claims their system shows no P availability regardless of DEL-YVR or DEL-YVR-YOW. Is EF ever inaccurate?

Any advice on what I can do in this case?

Seems like "married segments".

Upgrades avaible for those connecting through but not for the single flight.

Maybe since you have already upgraded one segment you are only identifird as for the single.

Perhaps call again and ask about this - they may be able to assist better.

I don�t think that�s the issue here because the agent claims they don�t see P class for just DEL-YVR either. And I tried searching for this flight on AC.com and the lowest Business Class fare I can find is Z: https://www.flyertalk.com/forum/31947502-post17.html

I�ve also tried multiple points of sale on EF (US, Canada, India) and get all the same. Odd...

FWIW, the mystery deepens:

If not married, then I am thinking just a poorly trained agent - that why I suggested you call again.

I do see HUACA worked for you eventually:

Indeed HUCA worked in the end. But it took a frustratingly amount of time to get this all worked out.

There are several other reasons I can think of that can influence availability and some of those are nearly impossible to emulate in Expertflyer...

The reasons include:

1) Point of sale (PoS) - availability in lower classes may significantly differ for sales via say US or UK (BA is good in that).
2) Further advancement - availability is depending on the point of origin or even a mix of parameters from your itinerary (including PoS).

To illustrate #2 say you are looking into the availability of NYC-PAR. The resulting availability will be different if your itinerary is
a) NYC-PAR-NYC and
b) PAR-NYC-PAR.
Moreover, the result can be different if you want to make changes to an existing reservaiton or making a new booking (this is how QR now requires to make changes to their bookings).

Another example is booking a trip with stopover on EK. EK requires that agents book stopover itineraries using the availability for a through itinerary on your departure date (if this is done manually of course).

I would say it becomes really difficult for a passenger to know what the 'applicable' availability is for his/ her case...

Super helpful! I think #2 was likely the case here, or maybe a combination of #1 and #2 .

Feature request:

If I've just created an alert, offer me an easy way to create a further alert with fields pre-filled -- the chances are high that I'll want to keep tabs on return and/or connecting flights. (ba97.com handles this well: after entering flight details I can choose between "add" and "add & populate return".)

You mean from the Create New Flight Alert page? Please email this to [email protected] so I can share internally to help with design, thanks.
