Maybe I am not a good bean counter, but I have to say, it is a convenience to some of your passengers. It would be an added service to someone like me who pays full fare and rarely if ever used her miles.
BA would like to keep someone like me around.
And at CDG, luggage pick up, EK had a separate conveyor belts, so it was a breeze to pick up the luggage and be out of there.
Gate to car was less than 10 minutes, and yes of course I had checked luggage.
