Delta Air Lines passengers could start seeing middle seats being filled up again in the middle of next year, the company’s CEO said this week. 

During Delta’s third-quarter earnings call on Tuesday, CEO Ed Bastian said he expects the airline will stop blocking middle seats in the first half of 2021 -- depending on how passengers feel. 

“It’s going to be [based] on consumer sentiment and confidence in air travel,” Bastian said, according to a transcript of the call.

And he said confidence in air travel is improving, he added.

“We've got a lot of studies coming out from experts about the safety of air travel. And sometime in the first half of next year, I have no doubt we will be lifting those caps. But we haven't picked a date yet, and I'd say we will continue to start the New Year with the caps in place.”
