Ocean Viking rescues 113 people in Mediterranean

Southwest Airlines says a winter storm moving west to east across the U.S. forced the airline to cancel thousands of flights as flight crews were not in the right locations to fly the planes.

Some 3,410 domestic and international flights were canceled Monday as of about 3 p.m. EDT, according to the tracking site FlightAware. The site said Southwest Airlines had 2,497 cancellations — about 60% of its scheduled flights and about 10 times as many as any other major U.S. carrier.

Based on FlightAware data, airports all across the U.S. were suffering from cancellations and delays, including Denver, Atlanta, Las Vegas, Seattle, Baltimore and Chicago.
