Lots of airline companies out there are offering frequent flyer programs. That's great -- you can collect points from a bunch of different programs and come up with a boatload.
Here's the catch. There are so many frequent flyer points floating around that they're losing value. It takes a ton of points to earn tickets or upgrade to a better seat. In some cases, the points expire more quickly, too. A secondary problem with frequent flyer and reward points is that airlines tempt you to spend more money than you normally would, because you want to build up those points. Although frequent flyer programs can come in handy, they're not always a fantastic deal.
