US carriers continue to count the cost of winter

US carriers are counting the cost of the delays and cancellations caused by this winter’s snow storms, which has been the worse for flight cancelations since records began 25 years ago. United has disclosed that it cancelled 23,000 flights due to bad weather in January and February, which the airline expects to hurt revenue figures. Delta Air Lines cancelled 17,000 flights that president Ed Bastian confirmed would cut revenue by $90 million and pretax earnings by $55 million. He added that Delta still expects to post a record profit for the first quarter nevertheless. American Airlines Group canceled 28,000 flights
