Hey little dog, your owner is waiting for you in gate 2
When a pet owner and their pet are separated, generally, the pet is found first and then the owner is called, right? That appears to be the standard procedure. That is why this situation has come as a surprise.
We have no idea what the people at LAX are eating or drinking, but we are not convinced that is the best strategy for reuniting an owner and their dog. We do not know if it would understand what gate 2 is or where it is in the airport either.
