Last fight of the day and within an hour of departure so wouldn’t think SDC is the answer.
App is not showing anyone upgraded.
Curiosity is getting the best of me. Me and my companion have been 1 and 2 since check in last night. The 1 seat available was about 30 minutes prior to the second screen shot.
Again not mad or upset just bored and curious prior to a slightly delayed flight. ATL-SRQ is the route and was the last flight of the day at 10:30pm.
Same thing happened on my recently completed PHL-ATL segment as well. 1 seat available (were 1 and 2) at T45 and it was gone by T30 with the gids showing no one upgraded.
