Flights to Northeast delayed by winter weather

Departure traffic destined to John F. Kennedy Airport in New York was experiencing delays averaging 2 hours and 48 minutes, the FAA said.

Delta and AirTran, the two main carriers flying out of Hartsfield-Jackson, were advising passengers that they could change travel plans without additional fees if they were flying to affected cities Friday and Saturday.

Delta "is offering customers whose flight plans may be affected by winter weather across the Northeast [Friday] and Saturday the ability to make one-time changes to their travel schedules without fees," Delta said in a statement. "Delta's weather advisory encourages customers to consider postponing or rerouting their travel to avoid possible inconvenience from expected flight delays.

"Customers booked on Delta-ticketed flights to, from or through the following states may immediately rebook for travel before or after their original travel dates as long as new flights are ticketed and rescheduled with travel beginning by Jan. 13:  New York,  New Jersey,  Pennsylvania, Massachusetts, Rhode Island and Connecticut."

AirTran said in a statement on its website, "Passengers who are traveling to, from or through the affected cities ... may adjust their travel dates one day prior or up to three days following their originally scheduled date of travel based on space availability, without change fees or fare adjustments."

The affected cities were Allentown, Pa.,  Atlantic City, Boston, Harrisburg, Pa., New York-LaGuardia, Philadelphia, Portland, Maine, and White Plains, N.Y.
