It’s been an up and down year for the airliners. There have been several viral incidents that sparked a barrage of negative press and backlash for companies like United, JetBlue, Delta, and American Airlines. Regardless of how you feel about flying, it remains the fastest way to travel long distances.

And even as these companies lower prices in an attempt to gain more market share, it’s surprisingly easy to rack up expenses on air travel. Here are a few flying hacks that can either save you money, time, or make flying a little more enjoyable.

The more you use your credit card  in your wallet, the more miles you can accrue, which can then be redeemed for flights at a great discount (or even free if you have enough). Capital One, Chase, and Discover are just a few of the companies that offer airline perks with their credit cards. Or check out the airline cards from American Airlines, Southwest, Delta and more. Depending on your departure airport and airline routes, one may make the most sense for you.
