you never know who you are going to sit next to on the plane! Last year, I boarded in BWI for my connection and got a great aisle seat in the third row (southwest)... turns out the four people in the row (two on each side) were regulars from Grand Pineapple and we had met and talked during a previous stay. needless to say, the party got started right away!
ETA: do you ever look around your plane and, even though you are all going to land in Montego Bay, you feel like you are the most excited, maybe the only excited, person on the plane??? Come on, people.... we are going to Jamaica... get pumped!!!!
