Airline credit cards and travel rewards
Credit card mileage programs can be a good way to rack up airline or hotel points, but only if you pay off your balance in full each month.

Air miles and free mileage programs
Travelhammer encourages you to enroll in frequent-flyer mileage programs for the benefits they provide. Once enrolled in an airline mileage program, you can earn free air miles that can be applied towards free flights.

Checking and cashing mileage points
Make the most from your airline and hotel points programs: Keep track of them and spend them wisely.
