Everyone's situation is different. I can understand the attraction to JB if someone is from the Boston area and wants to stay there.

But, if someone has no desire for international long haul they might think JB is a good choice.. However, you can do that at any of the big three, if you desire. I'm talking about relative seniority. My guess is that a pilot can have much better relative seniority on a narrow body at any of the big 3 during their last 10 years as a captain, than they could on the same equipment at JB. Heck, even the first 10 years at a big 3 airline could yield better relative seniority at the big 3 than at JB.

Again, each pilot needs to figure out what works best for their situation and no one else's. I'm just trying to offer something that people might possibly overlook.
