If you are traveling with someone, ask for an aisle and window seat in the same row. Middle seats are generally assigned last and have a good chance of remaining empty. Or simply ask to sit next to an empty seat if the flight is not full. Once everyone has boarded, feel free to move to the nearest empty seat. To avoid ear pain, wake up before the plane begins descent, allowing for gradual adjustment to the pressure changes.
Dehydration can cause muscle aches and cramps, dry eyes and skin.
Avoid consuming alcohol and caffeine substances, which promote dehydration. To encourage blood flow to the area, perform rotating movements with the ankles or get up for a walk around the cabin. Sleeping is often a challenge while flying. Try using earplugs, an eye cover or an inflatable neck pillow. It also helps to avoid alcohol or caffeine, which disrupts or inhibits sleep.
