Can I bring my insulin on the plane and do they have something to keep it cold

You can bring it on board, but you need to keep something that keeps it cold. Ice is provided

Im not sure about that. I know they accommodate or assign employees to elderly and young people flying that need assistance. I'm sure they get a lot of requests for help with insulin due to so many people being diabetic. But you will not be able to bring more than a certain amount inside of the airplane you will have to check anyting / 4 oz. And be careful because if your bag weighs more than 100 lb they will charge an extra fee. I'm not sure how much insulin you are planning on bringing I know that usually depends on how long you will be from home. But if you plan on being away 4 a while you might want to send your insulin through u.s. Postal Service or UPS or FedEx a few days before your flight. Can only bring what you need on the plane give yourself a few days Supply just in case something goes wrong with your mail. But definitely call whatever Airline you are flying on. They should be able to help good luck
