Why can't I use my KLM credit card rewards on other airlines?

Most airlines are very protective of their miles and don't allow you to redeem miles on non-partner airlines. However, there are ways for you to earn miles that are not tied to any airline. We recommend to get a general travel credit card. Rewards on such cards are neutral and you can redeem miles for travel purchases, surely, for plane tickets. The miles pile up fast and you can use them not only on KLM, but also on other airlines. A bunch of miles you'll get after using these cards will be enough for a number of roundtrip tickets - depending on how often you use, of course. The best results are reached when you put most of you purchases on a target credit card and quickly pay off the balance as soon as it appears.
