NEW YORK (AP) — Fourteen flights operated by American Eagle at Chicago O'Hare on May 29 were stuck on the tarmac for more than three hours, a day when thunderstorms led to hundreds of cancelled flights.

The Department of Transportation said Thursday a total of 16 planes waited on runways for more than three hours in May. That's four times the highest number of any month since the rule threatening huge fines for such delays was implemented in April of last year.

One flight coming in from El Paso, Texas, sat on the tarmac in Chicago for nearly four hours.

Overall, airlines were more on-time in May than in April. But they were late more frequently than in May 2010.
