I'd highly recommend using ear plugs when flying. Buy a cheap pack of foam ear plugs at any pharmacy and use them whenever you fly (also get in the habit of using ear plugs when mowing the lawn, blowing snow, firing guns, etc., anything loud). If you forget to buy ear plugs when flying, you can buy an overpriced pair at any airport. Too many of us ANers still insist on listening to Hotel California on ITunes for the millionth time while flying. Bad idea. Use ear plugs and read a good book instead. You might still experience the normal ear pain from the change in pressure, but your recovery will go from days to hours. Be proactive about protecting your hearing. Be well.
