I see Allegiant Air is starting to come around.
For several years, many airlines have had checked bag fees – but carry-ons are free. But it’s having carry-on bags that slows everyone down while inept and hapless travelers try to wedge their carry-on and “small personal item” into overhead bins, under the seat in front of them, or in a neighbor’s lap.
Let’s reverse that policy and allow one carry-on bag per person for free (laptop bag, backpack, purse, etc). Then have all other bags be checked (maybe charge over 3 checked bags – or not, that’d be up to the airlines).
I’d put money down that most everyone’s flights would be substantially smoother that way.
