Don’t be afraid to ask to be moved if necessary

Travel medicine physician, Dr Kunjana Mavunda, recommends her patients take common-sense precautions like wearing multi-layer or surgical masks instead of cloth masks, using sanitising wipes to clean their seat, and applying hand sanitiser. She also tells her patients that if someone around them isn’t observing COVID restrictions (for instance, the guy wearing his mask under his nose, or the one not wearing a mask at all) you should find a flight attendant and ask to be moved.
Don't fall asleep before take-off

If you do, it will be harder for you to equalise the pressure in your ears (which you’ll do more quickly if you chew gum or yawn).
If you’re prone to flight-induced headaches, hold off on your snooze until your ears pop.
Don’t forget to stay hydrated

Parched throat mid-flight? Don’t just blame the salty snacks. Airplane cabins are known for their low humidity because the manufactured air in the cabin is made to mimic the highest altitude humans can breathe at, usually between 1800 and 2400 metres, according to the World Health Organization. “For every leg of [a] flight, each flight attendant will try to drink a full 16 ounces of water,” says Ferguson. “That’s the most important. Hydrate, hydrate, hydrate.” You might not think of it as an airplane hack, but drinking plenty of water could be the difference between showing up at your destination refreshed and stepping off the plane with a headache.
