Both are technically more senior than NYC, but newhires have been getting both bases. If not, it may be only a few months before you could switch to either with the new monthly AE's.
1 and 2 day trips seem to go senior and locals. Reserve sees mostly 3-5 day rotations. 2-3 legs a day. If you get worked hard on the first day or so the last is typically a single shot. I wrote some other stuff a post or two above. If you anyone reading this is senior to me it is repetitive, lots of BOS/LGA/JFK turns and a small jet. Fairbanks in winter. Stay away!
