3. Check your email box
Remember to keep checking your email box before you leave your home. A few hours before the departure your air company may email you with nice offers. They will not be free. Some upgrades will cost, but they will be much cheaper than the regular ones. You can try and phone the airline, but before you do this simply open your email – the offer you’ve been looking for might already be yours.
4. Get sad
Emotional people either scare or provoke sympathy. In either case, once you demonstrate the staff how sad and stressed you are, they will try to do all possible to either get rid of you or help you out. Try and think of a good reason why you deserve a flight upgrade then.
