PHX is the most Senior Group 2 CA base, but a fairy Junior Group 2 FO base. Bottom FO is 15,XXX. LAX has some of the most expensive and crappy hotels with only LGA competing. There are tons of trips starting with red eyes from both LAX and PHX so commuting on the front end should not be too hard, but many trips get back late and you may be forced into a hotel or crash pad at either base. PHX has some of the best values for close hotels of any base. I would look to see which I’d remit her you could sit LCR from home at given the commuting options.
