No duh. Did the airlines just figure out that we're all carrying suitcases to put overhead instead of checking them? Or that with trying to find overhead space, gate-checking bags, helping the elderly folks to put their bags overhead, and the rest it takes twice as long to load a planeful of people as it used to, even with the flight attendants haranguing you to get out of the aisle? I'm grateful to the renegade check-in desk person for his action and hope that the higher-ups in the airlines, who have probably never flown coach in their lives, will start to rethink their position about charging for luggage.
[Edited to add: And I'd rather listen to a dozen babies cry than hear the loud-voiced blowhards who for some reason feel compelled to talk about various air disasters as we're taking off.]
