Always remember to check if your plane ticket has assigned seating or not.  Otherwise, you may be the last on the plane and end up sitting between two "curvier" women.

Having a layover for 3 hours at an airport can be really boring when you are traveling alone. To lessen the boredom, take a walk on the escalator, browse the books and check to see which celebrities have broken up with whom and what nose job has been done! That'll keep you entertained as well as help you get some exercise in!
