British Airways "CREW" style luggage tags are NOT valid as Airline Identification. They are designed to keep a crew members bag on the plane that they are flying. Use of "CREW" style tags by anyone other than a crew member may actually cause your bag to be mis-routed to another city.
We strongly advise you NOT to order a "CREW" style product if you are not a crew member. We have numerous other products available for you to choose from.
