United Airlines is responding to a viral photo posted online of one of their nearly full flights.

 

On Twitter, the airline wrote, “Starting next week, customers on flights that are expected to be closer to full capacity can rebook on a different flight or receive a travel credit. We'll do our best to reach out about 24 hours before departure and we'll also provide options at the gate.

A doctor posted a photo over the weekend on Twitter, showing what it was like on board a flight out of Newark to San Francisco.

The doctor questioned the airline's social distancing policy, saying, “I guess @united is relaxing their social distancing policy these days? Every seat full on this 737”

Last week, the airline said it would leave middle seats empty.
