Delta Air Lines altered its boarding procedures in hopes of preventing the spread of the coronavirus.
The Atlanta-based carrier is now boarding flights from back to front. Passengers are asked to stay seated in the waiting area until their row is announced.
The change, which took effect Friday, will remain in place at least through May 31, according to a post on Delta's website.
By boarding from back to front, the airline says there's less chance passengers will have to pass by each other as they find their seats.

Delta One and First Class passengers, as well as Diamond Medallion members, will continue to be able to board whenever they choose.
Earlier this month, Delta initiated a spaced boarding process that allowed fewer passengers at a time to board to prevent potential exposure to coronavirus.
In addition to the new back-to-front boarding process, Delta says it has taken a number of safety measures, including providing crews with masks. Customers are being asked to bring their own masks.

Cleaning procedures have been enhanced, as well, including spray fogging all aircraft.
Delta, like all major carriers, has drastically reduced the number of flights it operates each day as business and leisure travel has plummeted due to COVID-19 fears.
