I used to work for Eastern Air Charter a few years a go. Not a bad job if you don't mind being on pager 24/7.
However, I hear there have been some shake-ups there and the director of ops took some people and split to start his own company. I was told its called "Boston Air Charter" or some-such name with "Boston" in it.
I would definately look into this new company as he and the people he brought with him were the soul of the company.
I hear they are operating out of Norwood on the north ramp, but that they are planning to move to New Bedford and set up shop there.
