Delta Air Lines will stop blocking seats on its aircraft beginning May 1, the last major US carrier to end the policy as more travelers take to the air. The carrier has said many travelers have chosen it because it has kept the policy in place. In a statement, Ed Bastian, CEO, said that 65% of customers who flew Delta in 2019 said they expect to have at least one dose of a COVID-19 vaccine by May 1, and that is “giving us the assurance to offer customers the ability to choose any seat on our aircraft, while also introducing new services, products and rewards to support the journey.” Delta also announced other changes, including: tickets valid until the end of this year, as well as all tickets purchased this year, will be valid until the end of 2022; snacks will be brought back on board on April 14; and hot meals will return in early June in Delta One and first-class cabins and on some transcontinental flights.
