They should go back to offering free checked bags. I don't get why everyone thinks we should remove carry-ons. People didn't haev so many carry-ons when checking was free. If they really gave a damn to get us on faster, they would board the back of the plane first. But then that means people who paid more for their seat get on last. I always felt that the slowness just boils down to greed on the airline's part.
Which argues for the point you're replying to: why should an airline charge money at the ticket counter for a service you can get for free at the gate? It's perverse.
