I'm all for it. There are blogs out there that help these yahoos try and get around all the rules of air travel.
Since the people want the cheapest ticket, they get what they pay for and checking a bag is extra. We tried holding out at CAL when bag fee first came out under Larry Kellner but failed miserably. People aren't smart enough to think about bags and just click the cheapest ticket.
Those who try and screw the system make it hard for those who follow the rules. I think they should take a page from Spirit, Sun Country and Allegient and charge MORE to check the bag at the gate vs the counter.
