I hope someone here can help.....My son was just diagnosed with a double ear infection (poor kid) and we are leaving on Friday for WDW. He was given a prescription antibiotic in liquid form. We are flying out on Air Tran. Safety regulations say you can have a medication on your carryon if you have a prescription. Does the label on the bottle count or do I need a copy of the written prescription?Doctor said he should be fine to travel on Friday as long as antibiotics work. What timing! Thanks for any help!
