sunworshipper....you won't regret the extra leg room. also, FYI the tv only works for the first hour or so. it turns off as soon the plane hits international waters - right around virginia/DC area i believe. however, if you purchase a movie right before the tv's turn off, you can continue watching it until the movie ends.
xm radio works for the entire trip.
did i mention the best part of taking jb to aruba is that there's hardly any check-in lines at aua on your return flight home?
