The airlines cited different reasons for the mass cancellations and delays. JetBlue cited “severe weather in the Southeast and multiple air traffic control delay programs,” as a reason for the delays. Southwest Airlines blamed “weather and airspace congestion” and a “technology issue” for their cancelations and delays.
Alaska Airlines, whose cancelations affected more than 37,000 customers, did not give a reason for the delays but referred to contract negotiations with its pilots in a statement.
“Alaska Airlines failed to properly plan for increased travel demand and take the steps necessary to ensure it attracted and retained pilots,” the pilots’ union said.
President Joe Biden’s Secretary of Transportation Pete Buttigieg has remained silent while cancelations and delays hit airlines across the country. Interestingly, this is not the first wave of mass flight cancelations to happen under Biden’s administration.
