Anything that makes flying cheaper is okay by me. I’m actually sort of shocked that this hasn’t started up sooner. Why not charge for bags and drinks? If charging $10 a bag and $5 for a drink is going to cut the cost of the flight by 40%, sign me up for that.
Also, if you smoke, pass gas, or allow your cranky toddler to get on without doping her with Benadryl, you have to pay X-tra.
