There are three things I can say about frequent flyer points, frequent guest cards, etc… Join, join, and join. Even if you think that you will never fly the airline again or stay at the hotel again. You never know what perk, coupon, or travel tip you will receive. Sometimes the fact that you are a “member” is enough to help you out in a travel situation. TIP: Join only if it is free or the cost of a stamp. It is rarely worth paying for any of these clubs.
