The new service is a little different in operation.I guess I was a bit confused because I go to the counter to hand my bags off....
And before they always did give you your boarding pass and luggage tags in the envelop outside your door.
I understand they can't change your reservation.
Some airlines, some airports offer bag drop. The passenger is already checked and paid for luggage. The new service operates like a bag drop. The agent weighs the bag, gets it tagged and takes it.
