I actually like the idea of charging for carryon bags if, and this is a big IF, it is part of the evolution of bag fees and policies that actually makes sense. I think that the current system just creates a giant clusterf*** of a boarding process. I have always felt that there seems to be some kind of massive disconnect between ticketing and boarding. Doesn't feel like anyone follows the bag policies of one bag and one personal item. Or, they interpret personal item to mean an extra rollerboard or giant backpack. I am not a fan, long-term, of fees for carryon bags. I am a fan of pushing the industry to have a rational bag policy. Start enforcing your own rules and people will adjust and everything will be simpler.
