Also keep in mind the benefits package at each carrier. From talking to my buds at JetBlue, their insurance really sux and their 401K leaves a lot to be desired as well. Obviously, JetBlue is still a new carrier and a lot can change over time, but from what I've seen, NetJets' benefits can meet or beat any other company I've seen. At JetBlue, you'll obviously have the flight bennies, so maybe that evens it out. For me, going to NJA will be a $300/month raise just cuz I don't pay for my insurance. The 7/7 sched is exactly what I want as well.
A good friend of mine has been at JetBlue since August and is very happy flying the Bus. He just got a hard line in JFK which had less days off than he was getting on reserve. He bids for overnights in the city he lives, so he averages another 2-3 nights at home doing that. From what he's told me, if you're on reserve, they let you choose a 6/4, 5/3, or 4/2 schedule with all late starts/early finishes on the first/last day.
