One important tip: Book over the phone! That way you can ask all the questions you need to and easily find out the rules for the specific airline you are flying. Different airlines have different rules and requirements, and they may also change so find out what you need to know at the time you book your flight and you won't have any unpleasant surprises when you arrive at the airport.
Safe Travels!
