Theres more movement on the 73, whether that is significant or not really depends on what percent seniority you are and what base you’re in. It makes about a 2% difference for me in my seat and base so negligible difference for me, might be much bigger for someone else. That being said IAH 73 FO is the second biggest position in the company. That means much higher likelihood of finding P2P trades and other fun schedule modifications. I’ve found the 73 trips are, generally, better. That being said it’s exaggerated how good the 73 trips are and how bad the bus trips are. 4 legs a day is rare on the bus but it does happen. Bus tends to have more “RJ” overnights but this will trend the opposite way as the 19’s and 20’s get retired and the 21’s come on property. We’ll start seeing more Hawaii and transcons on the bus and I’m wagering more “RJ” overnights on the 73 as the smaller busses become more rare.

My take is that if you don’t mind the ergonomic differences go 73, but if you get “stuck” with the Airbus you may find it hard to willingly leave FiFi down the road.
