ATLANTA (AP) -- Delta Air Lines will stop blocking middle seats in May, meaning that no more U.S. airlines will limit capacity on flights to reduce the risk of spreading COVID-19.

Delta's announcement Wednesday reverses a policy that had been in place since last April.

At one time, several other airlines including Southwest, Alaska and JetBlue had also limited seating, while United never did and American did only for a short time.

Delta CEO Ed Bastian says nearly 65% of people who flew on Delta last year expect to have at least one dose of the new vaccines by May 1, giving Delta the confidence to sell flights to full capacity.
