NEW YORK (AP) — The government says 14 planes were stuck on the tarmac for over three hours in June. It was the second straight month that delays of three hours or more were in double digits since a rule went into effect threatening airlines with hefty fines for lengthy delays.

The Department of Transportation has yet to fine an airline for violating the rule.

June is one of the busiest travel months of the year, but in June 2010 there were only three delays of three hours or more.

Most delays this year were at Chicago O'Hare and Washington Dulles. The longest was an American Eagle flight from New York to St. Louis, stuck on the tarmac for four hours.

Overall, U.S. flights were on time more in June than a year earlier.
