#4: Be Sure You Subscribe To Frequent Flyer Program
Be a Frequent Flyer. If you join an airline’s frequent flyer program, you are far more likely to be at the front of the queue for an upgrade, as the airline will want to reward you for your loyalty. Even if you do not fly regularly, go to the airline’s website and join their program online. It will only take a minute or two, and is well worth the time.
