Airline industry insiders say passengers have become carried away with carry-on baggage, leading to costly delays. That’s prompting calls for changes to how airplanes charge for baggage, with some discount airlines like Sunwing and Spirit already beginning to flip the fee structure so passengers pay for the privilege of keeping their bags on board.
They changed the number of seats on a plane (added more in 2012 I think) but didn’t change the overhead storage.
It’s down to the last big update to FAA regulations. They maximized the number of seats and used a comped check-on system to accommodate the FAA carry-on requirements.
This is for Canada so I assume this is just airlines really screwing over a country that hasn’t put in a similar safeguard. UK seems to have the same issues.
