Hearing aids can be worn during the TSA security checkpoint, but air passengers may need to remove them if asked to do so. Almost all hearing aids are vented to regulate ear pressure, so removal for flying is not necessary unless desired. If pressure changes cause discomfort, try Ear Planes, which are available in drugstores. They change air pressure in the ear canal to reduce discomfort but cannot be worn with hearing aids. Remember to bring the case to store hearing aids.
