What's protocol on epipens on planes? My SIL wanted me to ask b/c she has one for herself and one for her daughter (3YO) that she needs to have with her. Is there anything specific she needs to do with it to get to keep it in her carry-on? Can she pack it and walk right thru? Does she need to take it out and put it thru security? Does she need proof of anything? Any help would be greatly appreciated! Thanks!
