First time flying and checking my backpacking pack. Was looking to see if anyone had advice on how to prepare the pack so all the straps, zippers and various other components don't get fouled up by luggage handlers and conveyor belts.

United's website said most stations have large clear plastic bags technically for protecting checked car seats that may be used for other things, but no guarantee they are available or will fit whatever you are checking.

Another option seems to be doing the saran wrap-type plastic wrapping, but not sure if that is available at IAD or if TSA decides to check out the bag they will just cut/rip it off.

There are pack travel bags that should fit my pack, but reviews say they are rather bulky and I'm not thrilled about having to haul around the additional weight.

Then there is just letting it go as is, cinching down all the straps and tucking in or typing off the loose ends as much as possible.

Anyone who has some advice or experience with checking packs and options at IAD (or MUC) would be appreciated.
