I've flown it a couple times now. PIT-OAK-PHX. BOS-MDW. Can't remember where else. Not sure what the plan is for them long term. I didn't know we were going to have one on the trip until I did the walkaround. Flies like the other jets as far as I can tell as a brand new guy. Did seem a bit quieter, and there was some music playing during boarding. Takes FOREVER for the engines to start.
