So I typically drive but this year I am going to fly and I've never flown with gear before. Will an emr2 with 26" frame work as a carry on, obviously not filled to capacity but more in day pack mode, or will it need checked? If checked are there any precautions I should take? Do you just check it as is or stuff the frame inside or maybe the whole pack in a cooler? Ever has your stuff damaged or lost? Anything else I'm not considering?
