1. Leaving to Delta is going to be competitive. Not all of us will get the chance to go there. Personally, I'm not interested in FedEx, UPS, United or US Airways/AA, so JetBlue is my ride unless/until I get on with Delta. I'm not holding my breath. With all of the flows they have, it will be hard to get in off the "street" for quite a while. If you're not in on the start of the wave, it may not be worth going to just be perma-junior for the next 30 years.
2. Money isn't everything. For me it's about the quality of life, and the culture of the pilot group. I want to enjoy being at work. I also want to live past 67, so FedEx is out. Those guys die early. Night flying and international work wears on you.
3. You can bid for, and get, time off during the summers using the PBS software and Flica. Is it "vacation?" No, but it is 15 days off in a row, over the change in months. I get that it isn't "guaranteed," and that you can't plan long-term. We need to overhaul the vacation system, no question. But it isn't really true to say that you can't get time off during the summer.
4. I agree the healthcare should be better (in a perfect world), but I'm not sure what we will be able to do about that given the national climate with respect to healthcare. I think Delta/United/AA will get dragged down to match as soon as their next negotiation comes around. It's a crap sandwich for the whole nation. Want that to be fixed? Vote for someone who will get a single-payer system in place, and/or reform the insurance industry as a whole. That whole industry is screwed up.
