Both the 757 and A300 Have the crappy old style interior without MRTC. IFE is basically old CRT TVs with CBS's Eye on American. Take your own headsets or you will have to pay 3 bucks for them. Dont expect any service on the flights other than drinks.
If you are staying in MIA
a few days or hours and can leave the airport I recomend the Hooters on 107th AVE NW
, you can sit outside and look at planes landing on R9
or 8R, And they pass almost directly overhead at about maybe 150 feet. not SXM
but its OK
In key west if you go to Sloopy Joes dont drink the RUM RUNNER, taste's like robitussin. Go to the sunset deck, get their early so you can have a seat by the sea, sunset is gourgeous, with an Ice Cold Corona and some oysters.....
God I need a vacation!
