- These days heed all warning about traveling with flammable (wax remover) or sharp objects (scrapers, etc) and bring extra ID, like your passport.
We've had some awkward explaining to do while traveling lately. "Well see, we have to use these to clean the klister - klister is this really sticky - actually you don't want to open that - well see, that's what you use the cleaning stuff for - sorry about your uniform. You want to see some extra ID?"
Keep a layer of glide wax on your skis when you aren't skiing on them, especially when traveling.
When flying, pack clothes around your skis inside the bag.
