My choice for flying is to replace the sporran with a travel vest. Take it off for X Ray like a sporran. Just much more comfy to fly in if needed. Stuff is better organized if I toss the travel vest in the overhead.

For the life of me I don't understand why all men don't kilt up for comfort when they fly. Todays sardine seating makes FREEDOM essential.

Perhaps some forward thinking kiltmaker will advertise in one of the inflight magazines..."Cramped up? - you could be FREE if you flew in a kilt"

A progressive airline would pass out kilts like they pass out little blankets and little pillows.
