I live in Orlando and about 20 minutes away from the Orlando/Sanford airport, which is where Pan Am is operating out of, please remember this is not the Orlando International Airport it is a small holiday charter airport, where Monarch, AirTours, and Air 2000 fly into. Recently i got to meet all thier employees at their maintenance faciltity at Sanford and they gave me a complete tour in and out of their 727, it is all economy, very very nice inside, completely renovated, they seats are OK their isnt enough leg-room. I personally find that it will be hard to make $ from Portsmouth, NH which is their supposed "connection" to New England, although it is a whole 2 hours away from Boston! Portsmouths' airport only has 1, yes i said 1 gate, sanford has 5, which are only for international aircraft. Domestic has walk-out gates.
