How are you all seeing this when I can't even log into my account nor am I am to verify my flight or seats? for this weekend?

Thanks. Will be interested to see if the Multiplier option appears when I check in. It's normally available as soon as a trip is booked, which is why I suspected the program had been discontinued.

Well, this is an interesting (ahem, concerning) first. I'm now unable to check in for the flight for which I've been upgraded (but have no actual seat). I thought the seats in row 1 would open up today. Instead, the system tells me I have to check in at the airport. Does this mean I may not be in F at all? If anyone has access to Expert Flyer, this is US 1808 (ATL to CLT) tomorrow. It's currently showing 1A as blocked, so maybe that one will open tomorrow. Has anyone seem a situation like this prior to the fare class changes? Thanks.

Whenever that happens to me (upgraded w/o seat assignment and to be assigned at airport), I invariably end up with 1A ...

1A is the reserved handicap seat and US prefers that it be assigned at airport.

If unable to do OLCI w/o seat assignment, then call the Preferred desk to get the seat assigned beforehand - they always say they reserve the right to change seats for a handicapped FC pax, and that's perfectly OK with me.

If you're confirmed into F, I wouldn't lose sleep over it. US doesn't oversell first.

Glad to hear this isn't a brand new issue. Guess I've always been lucky to get a seat assignment at the upgrade window. I called but their system is wonky and eventually disconnected me and said to call later. I'm guessing if they're overloaded with weather issues, they may not even be handling seat assignment requests. Since I have to check a bag anyway (and the agent that's likely working always insists upon printing out paper boarding passes to supplement my mobile ones), I may as well wait until the morning.

For those wondering, the upgrade to A posted correctly (100% of miles, not 150%), must be an error with the mileage multiplier screen.

Thanks. They're no longer selling F seats on the flight, so at I'm guessing 1A will eventually be mine. It's interesting that the upgrade list shows 0 checked in, so maybe OLCI isn't working for people with seat assignments either. There's one person on the list, and that's not me.

Thanks for the follow up. I still have no DM Multiplier option for my flights tomorrow, although it is present for my itinerary next week. Lots of system bugs, apparently.

I figured as much. When I looked the mileage multiplier page prior to check-in it showed @ 150% but when I checked in it correctly showed as 100%. At that point I assumed the chance was slim.

Update: just got the "Check in for your upcoming trip" email. Since it's several hours late, I thought, hey, maybe it was delayed for a reason. Sure enough, I'd already been assigned to 1A and was able to check in normally. Now if this no-seat-assignment ever happens in the future, I'll just be more patient.

I've recently bought three non-refundable F tickets. The first fare code starts AA (well, one of the flights says AD) - which makes sense to me, since I'm assuming they're A fares.

The fare code for the other two are different - on one, the two flights' fare codes start with SA, on the other they start with QA. These aren't upgraded flights, just non-refundable first. Will these earn normal F mileage?

Ignore my question above - I can see now that the booking code for all of them is, in fact, P. Which makes sense.

On Expert Flyer non 0 X bucket availablity is now showing up for some US flights.

Which is the new fare class for preferred upgrade availability - A or X?
