Last year Elva and I flew to and from here,Portland,Ore, to Ohio non-stop. Almost five hrs each way. I was kilted in both directions and enjoyed every minute of being kilted on the trip.
So go for the kilt!! If nothing else you will have the braging rights to the fact you flew to Ireland in a kilt.
Do it and enjoy. If things are not to your liki'n you can always wear pants on the return trip.
I am assuming this is a round trip.
