Earplanes are a must for me, they are found and any drug store or big box store with a pharmacy. Ask the Pharmacist for help some times they are hard to find in the displays. And they usually sell for under $10. I have even made the mistake of forgetting them in my checked bags once and found them at an airport news stand and they were only $12, I now keep a back up pair in my carry on or laptop bag. Worth every cent, in the past I would loose my hearing for a week or more when I flew. After I started using Earplanes no issues. I get 1 set for my out going flight and 1 set for my return, they don't not work as well if you reuse them, as I recall the instructions say the are a 1 time use. They also come in Child and Adult sizes you want a tight fit, at 15 depending on the person you may want to try both and see which fits best.
