Recently I’ve been traveling to Germany and Japan for business. My return flights are through New York. My chest actually tightens when I get off the plane at La Guardia.
The La Guardia perimeter rule prohibits nonstop flights to or from points beyond 1,500 miles.
All international traffic goes via JFK.
La Guardia has flights to Canada, Aruba and the Bahamas, possibly others based on its Wikipedia page.
