Seat Map vs. ExpertFlyer
 

I'm new to using EF, so would love some support if someone is willing.

I'm scheduled to fly AA243 SFO > JFK at 7am on Tuesday the 2nd and I'm playing the "will I get upgraded" game.

aa.com seat map currently shows 5 available business class seats.
EF search shows "at least 7" from the results page, but then only 5 from the seat map page.

Which, of all of these results, is actually accurate?

Also, being past the 100 hour mark, can I assume that all EXP's would have been upgraded already?

Sorry for the basic questions. Thanks in advance for the help!

AA is an airline that operates flights
ExpertFlyer is not an airline and does not operate flights.
Seats allocated/unallocated (seat map) is not the same as seat sold. Not everyone selects a seat.
Unsold seats may not be available for upgrade. Airlines want to sell seats for real cash money

AA may be willing to oversell Business because they know they can make room by upgrading some passengers from Business to First (either op-ups or clearing upgrades currently waitlisted using an instrument). The flight is currently F7 J7 with 8 unassigned seats in F. I bet if another 1 or 2 F fares sold, it would go down to J6.

Anecdotally, I've found to be EF pretty accurate when it comes to the seat map. As others have mentioned, AA may oversell the J cabin because they can op-up people to F. The 100 hour mark is only the earliest upgrades can clear. Don't assume any, and certainly not all, EXPs have been upgraded.

Awesome. Very helpful. Thank you!

I find EF helpful in several ways. It shows seats that are blocked but unoccupied. The AA seat map does not distinguish between blocked and occupied. Also, as departure approaches AA will block access to the seat map but you can still view it in EF right until the flight is closed. Very helpful to spot a seat that opens up close to or after boarding, which you can then get the agent to switch you into.

I think all the data you have is accurate, but they mean different things. Occupied seats on EF gives you the best estimate of the minimum number of sold tickets (though people can cancel or change to a different flight quite commonly), but F7 J7 tells you little about how many J passengers haven't deleted seats yet because those J7 tickets really only tell you that they will sell 7 more premium seats - my experience is that F and J will decrease (or increase) together.

Also, remember that Y may be oversold already, so the F7 J7 could also be factoring in the need to upgrade a few Y passengers.

Pre-Covid I often found myself on the Y-J upgrade list with a full cabin of J passengers and yet I still got an upgrade because they need to bump people forward to fill the plane.

This may be the least helpful reply I’ve seen on flyer talk, and that’s saying something.

OP—it sounds like the seats maps do match between the two sources, as I would expect them to.

J7 does not mean there are at least seven seats left, it means that AA is willing to sell at least seven seats. The business cabin on a three cabin flight is regularly overbooked, because in reality they can sell 30 seats in a 20 seat cabin and upgrade 10 to F. It’s not always that aggressive, but that’s the gist.
