Delta Air Lines said on Wednesday it will keep middle seats empty on its flights through March, an extension of the social distancing policy it put in place at the start of the pandemic.

Delta maintains it is the only US airline to keep blocking middle seats on its flights.

The move comes as other airlines are ending similar policies, gearing up for a potential onslaught of air travelers during the busy holiday rush.

Last week, JetBlue announced it will start to phase out capping capacity on its flights – currently 70% – and fill every seat starting January 8, 2021.

Southwest Airlines said in September it will fill every seat after November 30, following the Thanksgiving travel period.
