Have you taken a US domestic flight? Everyone wants to bring their massive roll-ons into the cabin, nobody wants to check if they can avoid it.

Indeed, although today I got on a plane at LaGuardia and they made me check my carry on at the gate even though there was plenty of space in the overhead bins ( 60% capacity flight, about half of us had to do this) so YMMV.

No idea why they made us do that, but I had to grab my bag at the luggage claim.
