This is a great little organiser to attach to your wheeled carry on luggage handles. Its a nifty little pouch to store your passport and boarding pass and mini tablets and earphones for easy retrieval.  There is even a bungee strap to keep other loose baggage secure.  
Once on board, simply place the pouch in your seat pocket while you store your luggage in the overhead compartment.
