1. Less worry, less fatigue
A lot of flight fatigue comes from unconsciously (and often consciously) worrying about things that might occur during flight - where your passport is, can you get your connecting flight and so forth. Much of this worry can be alleviated by keeping all flight essentials in one place so you know where they are at all times. One tip which helps is to keep a special over-the-shoulder bag which only gets worn on flights - your mind automatically comes to associate this storage place with flying, and you easily form the habit of returning your passport or tickets there every time they are handed back to you.

2. Arrive in plenty of time.
Those looking to make the most of every moment might try to time arriving with minutes to spare, but with experience, you soon come to know that the aggravation and worry that comes from standing in a check-in queue wondering if you will get there before it closes just isn’t worth it. You can easily think of something productive to do once you are safely relaxing in the departure lounge.

3. Master your sleep patterns.

4. Don’t overindulge in food or alcohol.

5. Hunt down that privileged traveler status.
