How do you prevent ear pain and popping on an airplane and after a flight?

Have you tried EarPlanes?  They're designed to regulate air pressure changes during flight.

Here's an example of a positive review, at the bottom of this page.  I hope that this helps!

Nose spray also helps.  I first heard about it from a seasoned flight attendant and thought she was crazy.  I then decided to give her advice a try and IT REALLY WORKED!  I have been a travel agent for over 20 years and have passed on the advice to many clients and they have all loved it.  Good luck.

I had the same problem when i went to disney world in august!!! i was in so much pain (btw im only 13) but i kinda had a cold but when i left chicago it was so much fun on the plan and then when it was time to land in florida my ears were popin so bad i was crying and the flight attndent gave me advice. she said to yawn but i cant it really hurts my ears and i could not hear half my trip!!! but when i got back a took a sleeping piles and ear plugs and ur ears will pop a little but not soo bad i mean u will only hear the pop not feel so i recommend that and i have really sensetive ears and i stilll will not get on a plane wit out earplougs and 1 sleeping plie from my doctor!!! hoped i help this made me cry i just went back to the pain i was in on the plain!!!

maybe when you travel i plane try to bring mp4 and ear phone just try to listen to music while you are on the plane try to sleep

i've tried earplane and it was good it gives me peaceful flight.
