LAS by far. After that, probably FLL, MCO, and IAH.

You can bid whatever you want, you’ll get what your seniority can hold. With enough seniority, there are commutable trips out there, but I’m not there yet. Lots of early starts and/or late finishes, and lots of trips with red eyes in the middle of pairings. If you’re a commuter, you’ll be spending some money on hotels or crash pads. I personally don’t mind, but legacy trips will generally be more commutable just because of the route network/structure.
