I have the getting through airport security down, but I'm wondering, what's the best way to transport vials of insulin on a long flight. I've not travelled enough since my diagnosis to be sure what to do with the insulin. Should I put it in an insulated lunch bag with an ice pack and carry it on or will it need more? I'm leaving Seattle at 9 am and arriving in Honolulu six hours later which is noon local time. I can deal with the eating issues and the jet lag but I don't want my insulin to go bad. I know I have to change my infusion set at least once on this trip, maybe twice. What do you normally do?
