Flying on flight 231 tomorrow IAD-SAN, and for weeks its been listed as an A319. Looking today at UA’s electronic timetables, a fake booking at UAL, and Classual.com all still show it as an A319. I’m waitlisted for an upgrade using a CR-1 and the buckets on UAL.com show it as F1 .

Today checking in with Mr. Easy OLCI under aircraft type it stated that it was an A320 . However, the coach seat map was for an A319 (No A or F seat in row 11). Also just did a fake first class booking and the F seat map showed the 2 row configuration of the A319 as well.

So has UA swapped an A320 for the A319 and my upgrade odds are a lot better (F5 vs. F1)? I've seen 319s and 320s swapped may times on my flights, but it hasn't helped me yet - maybe there's a first time
