I recently was helping a man who is going to be traveling to another country with a suitcase full of his disposable underwear. He was concerned about the Security areas he'd have to go through and also how the airlines would handle his baggage. We found out that you should call the TSA in the US and your airline ahead of time to make sure that you can get a private screening at Security in the airport, and also to check with the airline's policy on medical supplies before your arrival. There are slight differences from airline to airline on their policies with medical devices and supplies.
I am wondering if this community could share other good travel tips on long trips/or short trips with incontinence products that might help others not run into snags at airports, train stations, etc.
