I am collecting airline frequent flyer cards. I am wondering if you may know of any airlines that send you a card without flying with them. Let me know. Thanks.
Pretty much every airline I know of will send you a card when you sign up for their program, you don’t necessarily have to fly them.
Most US airlines don’t send the cards anymore.
I have cards from Delta, USAirways and Air France/KLM. They all were sent to me as soon as I signed up.
These days, most airlines will sign you up and give you a number but won’t send you a card until you’ve completed a flight. It’s a cost cutting move as some people sign up but then end up not flying so it costs the airlines too much money for them to go to waste.
