Insurance premiums vary widely, with 100, 90, and 80% PPO plans and a high deductible HSA plan, plus options for individual, couple, self and kids, and whole family coverage.
30-40% of each base/seat are on reserve. On the 320, CLT is the largest East base with almost 400 crews, PHL has almost 200, and DCA almost 100. On the 737, CLT is also the largest base - 150-ish crews, PHL has 60-some, and 30-some in DCA. The 190 is only in PHL, with about 80 crews.
Aircraft are equipped with shipsets, and pilots don't carry flight cases.
New hires last year and this year have gotten DCA 320 off the bat, and 2011 hires can hold 737, 320, and 190 in any base (on the East, of course).
