Delta said it will no longer book the middle seat on flights through the end of May in an effort to allow for social distancing.
Delta said it is also pausing automatic, advance seat upgrades.
"These will now be processed at the gate – still in priority order – to allow gate agents to determine how to best seat customers while considering social distancing and aircraft weight-and-balance restrictions," said the airline.
Some context: Delta and other airlines have already been slashing schedules and reporting a low level of passenger traffic on flights.
For example, Delta CEO Ed Bastian told Delta employees that it would be reducing its schedule by 80% in April due to the lack of demand, that it expects second quarter revenue to be down 90% and that on March 28, it carried only 38,000 customers, versus its normal late-March Saturday traffic of 600,000.
