Looking at my SEA-IAH flight tomorrow, I'm seeing F2 U0 A0. I'm MVP and on the wait listed for first class. If I check in now and get my coach seat, will I be taken off the first class waitlist? Or will I remain on the waitlist with a possible call up at the boarding gate if "U" space opens up before the flight? (I'm assuming that all empty F seats are converted to "U" inventory around boarding time).
My question boils down to whether there's an advantage to checking in now or should I wait to check in until I get to the airport in this particular case.
Thanks.
