A change so drastic that travel experts suggests maybe you should drop them as your favorite.
United Airlines is the latest airline to change the way you earn frequent flyer miles, joining Delta, JetBlue and Southwest. The airlines are now basing points earned on money spent, not miles flown.
The Points Guy founder, Brian Kelly says this will really separate elite and business travelers from economy class.
"In the grand scheme of things most leisure travelers are going to feel the pinch on this one," says Kelly.
Because of their merger, it may be a year or longer before American and U.S. Airways join the club. But Kelly and other travel experts say maybe it's time for consumers to take a good look at their loyalty program.
Kelly says, "If you've been flying a certain airline blindly simply because you think that you're getting a lot back in return it may be time to think differently."
"Think differently" not by joining another airline's frequent flyer, but by relying, for example, on credit cards which they say are the easiest way to rack up miles these days.
