Actually, that is true to some degree.
is the busiest airport in the region in terms of passengers because most of the aircraft using the airport are widebodies that carry 200+ people. This is not the case at LGA
. They have more flights on a daily basis with smaller aircraft (although EWR
gets its fair share of widebodies).
As a result, if the WX
goes sour, there are more aircraft to shuffle at LGA
HOWEVER, the real reason behind the delays lies with the airports themselves. JFK
is much larger and the runway configuration is much better to handle a large amount of traffic. LGA
is at capacity all day long; that's why it is slot restricted. EWR
is near capacity at all times. Both airports have the worst delays in the nation even under normal circumstances.
