As awesome as using points and miles are to book flights, sometimes you have to pay cash for your flights. Whether you found a great deal on airfare, or there just isn’t award availability and you’re absolutely itching to take a trip, sometimes paying for flights just works better. When you’re looking to buy a flight, you should be using the best credit card to buy a flight.

Even when you are booking an award flight, there are inevitable taxes and fees that you just can’t avoid.

But that’s easier said than done.
