Depends....
If you want to avoid airlining as much as possible, work out of CMH.
I was dispatched in a Ultra there almost 80% of the time. When I bid
MCO as a gateway, I saw about a 60% chance of flying an aircraft out
of the airport because of the Cessna service center there.
It is very common to pick up an aircraft out of TEB or HPN. Generally
speaking, the farther you like from the N.E. corridor you live, the more
likely that you'll airline to the aircraft. Also, the large fleets (Ultra, X)
have a better chance of flying one out than the smaller fleets (VII, 800)
simply due to random chance of pairing up.
If you never want to work at all, bid SEA. (I'm not kidding.)
