Thanks for the explanation - but I got the result I mentioned at the time that I was posting yesterday, using exactly the data that I set out.

And I have just got the same result now on a similar BA-only search (HKG).

The antepenultimate and penultimate columns on the Fare Information Results page were blank - they were missing the "page" icon and the "routing" icon.

Unfortunately, the Advance Purchase Required column was fine so I didn't get a chance to use the word preantepenultimate which disappoints me greatly

But all is back to normal now so probably just a foiled Putin attack on ExpertFlyer.

Thanks for responding

The seatmap for VN premium economy in EF returns business class seatmap. Could you please fix this bug? Shall be an easy one.

That depends, please email us the flight information.

What source does EF use to pull Aer Lingus award availability? Apparently United has been known to have phantom availability and I was wondering if it was the same as EF///

thanks

It is coming direct from the airline reservation systems.

-EFV

It does not to other sources:) I would double check. It is clearly another cabin then booking via travel agents. Possibly an incorrect letter in a query.

Nothing to double check. The Aer Lingus award inventory on ExpertFlyer comes from the airline reservation systems, which mirrors other accurate sources as per this thread: https://www.flyertalk.com/forum/aer-...l#post28486100

My question was about Vietnam airlines' seatmap for premium economy. Its not for the first time to persude the EF team, so I know I need some persistence.

If you say the business class seatmap comes for a premium economy cabin directly from the airline in the source you use, please name the source and i will book business class there at the price or premium economy:D

Expedia shows 2-3-2 seatmap for premium economy on VN and that's what it shall be.

FlyingDoctorwu was asking about Aer Lingus and that's what we are referring to. If you need help with a VN flight please email us the details directly.

Trying to create inventory alert for PER-BKK in December Y and F.

I cant seem to pull up the flights under "award and upgrades" for most dates even though there are flights everyday.

But if search under flight availability, the flights shows up?

Not sure what airline you are referring to, but as likely noted at the top of the results page, many airlines don't return flights that don't have any award inventory in any cabin.

You can still create a Flight Alert for the flight from the results page of the Flight Availability search or via the Create New Flight Alert page. Also you can add a general class, like Y, as an Other Class in the Award search to make the flight show.

I know Expert Flyer can alert you when certain Award travel becomes available. But for flights that are ALREADY available, can it tell you when it first became available?

For example, on Jan 10, 2018, I see J saaver availability for 2, LAX-PHL-FCO, all on AA metal. Flights 698 and 718.

Very interested if these have been available for a long time, or just recently released as sAAver. Can I find such info with an Expert Flyer subscription?? Thanks

No I'm sorry we don't store historical availability information.

I'm fairly good up to the intermediate level on ExpertFlyer but using the information, such as a fare basis, to construct a fare elsewhere baffles me.

Can anybody recommend any blog posts or other tools that will guide me through the process?

This post was a good start but I haven't been able to replicate the fare the author found, nor other fares EF returned. Presumably I'm missing a step or two but without some detailed guidance I'm at a loss.
