Jeans really aren't comfortable though (and I'm OLD!
). Rohan make all these clothes for travelling that are comfortable, have loads of zip pockets so odds and ends don't fall out, are lightweight, windproof etc etc etc. They don't advertise that they're good for flying, but they are. Bit pricy, but less than anything which calls itself flying gear. I'm about to go buy a pair of their convertibles (zip off legs to turn them into shorts) for flying in LA in April. Hmmm... after this post maybe I should ask them for commission.
