The city's regional airports have won the dubious honor of being the most delayed in the nation.

The Global Gateway Alliance ranked Kennedy, LaGuardia and Newark-Liberty airports last when it came to on-time performance in 2015. 

They swept the bottom three spots for punctual arrivals among the country's 29 major airports.

The GGA considers a late flight to be any that arrives or departs more than 15 minutes beyond its scheduled time.

They blame the city's poor rating on the high volume of passengers, outdated radar systems and a lack of adequate landing space.
