Just sneakin' around....
Okay, now I know you are a liar. There is no such thing.
I was coming from Arkansas to DC, had a cattle car seat. Got a message in the app that a 1st class upgrade was available, so I checked it out. $80 for an upgrade, 2 free checked bags. I had to pay $40 for my one bag in coach, so deduct the $40 I would have had to pay anyway, and the upgrade was $40. Not to mention personalized service, free drinks, and there was only one other 1st class traveler. Nice being addressed by name by the attendants.
