i am no longer from the boston area (waltham)
we are now in the tampa bay area and our last 2 aruba trips (aug and dec 2010) were on air tran via orlando international airport.
0 complaints (we did fly business class and there is no real food and no movie)
but i do have to say the flights were good and priced ok.
from boston, i would guess you'd make a connection at either atl or mco.
mco might be an easier airport to make the connection.
