I have a flight in about 3 days going abroad and I have this huge medical thing on my arm. Since it gets dry easily, and its a long flight, am i allowed to bring medicated over the counter ointment in my carry on? Do I still have to but it in the zip-lock baggie and such? My mother also has prescription medicine for travel sickness and she also asks if the meds also need to be in the baggie? Need answer please!
