I am scheduled on UA 0003 tomorrow, JFK-SFO. I'm flying C, and anticipating the scheduled 762 reserved 11F some time ago.

I went to check the seatmap this morning and it wasn't retrievable. Now I just looked up the flight status on united.com and it says this:

Airline: United
Flight: 3
Date: Wed, Oct 1
Status: NOT DEPARTED
Aircraft type: Boeing 767-300
Miles earned: 2586

Is it probable I'll really get a 763 tomorrow ? I've been morphed from a 763 to a 762, and I've heard the reverse can happen, but I'm having a hard time accepting I may actually be lucking out here.

Any insight is much appreciated !
