A new study commissioned by the Port Authority of New York and New Jersey calls for the major expansion of all three New York area hubs.

The report predicts that traffic at JFK and LaGuardia Airports in Queens and Newark Liberty International in New Jersey could rise 50 percent over the next two decades.

Without expansion, that could spell disaster for LaGuardia and Newark International, two airports that consistently rank worst in on-time performance.

The plan calls for a $15 billion overhaul that would add additional runways at JFK and Newark while expanding PATH train service to Liberty International.

The report notes that LaGuardia currently has no room to expand but calls for major upgrades to its existing infrastructure.
