This is actually one of the reasons I don't really care to lug around a headset. I use a small rollaboard (can be a backpack as well) that is my luggage and flight kit. I pretty much only do 1 and 2 days, so it's perfect for that, but 3 days are a stretch. So unless it's a super compact headset, I don't have much room thanks to my trip length +1 packing lol.
