Get used to a new time zone by going along with the local meal and bedtime schedules. Melatonin may help with jet lag, but no one knows how long it can be used safely. Tell your doctor if you plan to take melatonin or any other herbal medicines. If you usually have ear pain while flying, try taking a decongestant medicine before you get on the plane the next time you travel. You can also swallow often and chew gum during the flight.
Babies can suck on a bottle or a pacifier during the flight.
These tips work better if you try them before your ears start to hurt. Even healthy people can get blood clots in their legs after long flights. It also helps to drink enough water, to stretch your calf muscles while you're sitting and to wear support stockings. If your doctor wants you to take oxygen when you travel, remember to tell the airline about this way ahead of your flight. The airline will provide oxygen for you, for a fee.
