I spend pretty much every christmas in the air. Except for FAs wearing Santa hats, nothing special.
This year I'm flying EWR-TLV coach and I'll turn 29, on dec. 22nd, in the air.
Considering I just made plat and my return is in BF, + the flight is already showing as almost full, I'm hoping being very nice to the check-in agent might get me an upgrade as a birthday gift (and if not, then I'll be nice with the PC agent, and if not, with the GA, and if not... well, too bad for me). Not very likely, I know.
