weather and labour actions has grounded some US flights.

In Bermuda, Delta Airlines has cancelled Christmas Day flights from Atlanta and to Boston.

Flight 354 from Atlanta to Bermuda, arriving 3.50 p.m. and Flight 210 Bermuda to Boston, departing 5 p.m. were both cancelled.

An international spokesperson confirmed Delta Airline pilots refused to work the overtime and sustain Delta operations.

AP News reported that Delta has trimmed its schedule of 2,700 daily flights by an average of 100 to 125 flights a day to compensate for the work action.

Delta's cancellations spiked at the end of November as it ran out of reserve pilots to draw on, having used them up earlier. For December, "we've tried to manage our reserves to be able to try to provide consistent service throughout the month,'' spokesman Russ Williams said.

Another Delta spokesperson, Cindy Kurczewski told Reuters, "We do expect significant cancellations because of reduced pilot availability.'' So far, only one returning student was routed to Bermuda via New York City but both John F. Kennedy and LaGuardia Airports have been heavily affected by snow, frozen ground vehicles and sleet.

In Chicago, flights to LaGuardia were cancelled after diesel-powered runway equipment and fuel trucks failed when fuel turned gelatinous in the cold.

Eight departing flights were cancelled on Thursday, affecting a further line of flights.

In Georgia, freezing rain made roads slippery and cancelled some flights at the Atlanta airport.
