We fly when the distances or destinations call for it.
Flying to Florida is pretty much a "shuttle" service. I am not aware
of any carriers flying from Boston, New York or mid Atlantic states to
or from Florida that offer anything other than cattle car class.
Delta will put you in a pretty nice 1st class seat with priority at
TSA and priority ticketing, boarding etc. It isn't quite like the 60s
"friendly skies" but it is close.
