Has anything larger than a 757 regularly operated from LGA?
Air Canada operated L-1011 and B-767 aircraft into LGA . I had a few flights in there as a newly minted F/E on the L-1011 in 1980. Later I flew the DC-9 in there a lot, and Airbus 319/320. In those days the controllers would ask, "Have you got the GW"? If you said yes they would clear you for a visual down the Hudson. You could get the right turn in for 31, coming from the North too, if you asked nicely.
Always wanted to do an Expressway Visual in there with the 767 but never got the chance..
