I always fly with my car keys (almost always in my carry-on bag) even when I take the train to the airport. Simply because my car keys are on the same keychain as my house keys, and I never leave home for anything without those..

Oops, I am so used to taking a taxi (I don't drive) to the airport that I completely forgot many people actually drive there... Quite an idiot moment.

Have you ever seen the parking lots that surround airports? What did you think they're there for?

I never drive to the airport (parking is expensive and the train is cheap), but my car keys stay on my keychain and my keychain travels with me.

I have a combo lock at home. So I leave my keys at home unless I'm driving to the airport.

> who flies with car keys?

Literally everyone who parked at the airport?

I guess people who require a car in the transportation pipeline leading up to the airport? Even if you don't drive to the airport directly, you might drive to the train station that has trains going to the airport, and then leave your car at that train station.

Yes, but my point is that if they agree car keys are banned then AirTags are banned.

If they say car keys are fine then they have no standing for banning AirTags.

And yes, I agree that checking one’s car keys is silly.

I think it’s a stupid decision by Lufthansa, but to be fair, these keys will only transmit when prompted by a radio signal from a specific car, whereas an AirTag will transmit when prompted by any iPhone. There are, surprisingly, more iPhones inside the typical airplane than cars.

Lots of people travel with car keys if they drive to the airport. But it would be pretty dumb to put them in checked luggage.

Why do you think airports have parking lots? Tons of people drive to the airport before flying
