Mods; please feel free to move this if there is a better thread. I'm currently booked on flight #1791 on August 12 from SFO-ORD. Yesterday the plane was down gaged from an A321 Neo to an A320. Kind of wanted to try the Neo, but ok. Today I went out to see what the load looked like and the flight is no longer showing on the schedule. Even with the down gage, I find it tough to believe a 2:55 pm flight on a Tuesday is sold out. Is there any other source to check beyond the App and .bomb to see if the flight is still on the schedule? I don't want to wake up 10 days from now and see that it's cancelled and my options are limited. Thoughts?
