1. Wear glasses instead of contacts

Wearing contacts while flying isn't ideal because your contacts will dry up once you're at a high altitude. It's much easier to wear glasses.

2. Check in for your flight online

Checking in for your flight saves you time at the airport and allows you to avoid waiting in line. Carriers like Delta allow you to switch your assigned seat with any extras available once you check in.

3. Always travel with gum

Whenever I'm flying, I always have to have gum to avoid my ears from popping. It's better to buy some from your local grocery store than to realize you need it on the plane.

4. Never forget your headphones

Headphones are very important when going on a trip. Carriers like Southwest provide in-flight entertainment, but watching TV in an airplane without headphones disturbs the people around you.

5. Have a blanket with you

I always seem to be cold in an airplane, so I make sure to have a blanket or jacket with me in the air. Sometimes airplanes will give you one, but it's always better to have your own.

6. Have snacks for the airport and flight

As someone whose flight has gotten delayed many times, it is always best to carry around foods and snacks. Airport food is always expensive, and airport security allows you to take food with you. Make sure not to bring water with you because it will be taken during security checkpoints.

7. Wear minimal amounts of jewelry

Jewelry at an airport is never ideal, especially if it is expensive. During security, you will have to take it all off, and it's better to save yourself the trouble.
