Fares are well priced, I may end up on the first ABQ - JFK flight on 4/22 which currently has a ton of empty seats. The fare is $130, which is cheaper than AA which is $146 (and includes a stop at the beautiful DFW airport).
ABQ has plenty of space, if B6 wants to add more flights. I do think it's a odd expansion choice for B6, since I can't see much demand for more than 1-2 direct flights to ABQ from NYC/BOS.
