(KCEN) -- If you fly Frontier Airlines, you'd better stay faithful or pay. Literally.
Frontier is the latest airlines to guide more travelers away from sites such as Travelocity and Orbitz.
Instead, the airline wants customers to book tickets directly from its own website or be penalized.
So what are those penalties they will implement?
No seat assignment until check-in, higher fees and 50 percent fewer frequent-flier miles than earned on tickets purchased on frontier's website are some of the penalties.
