Delta Air Lines has continued to add to their new protocols in light of coronavirus. Starting June 1, new plexiglass shields will create a barrier at check-in desks between passengers and employees and floor markings will indicate how far apart passengers should stand while waiting to check in or check their luggage. The plexiglass safety barriers will also appear at departure gates and Delta Sky Club counters at Delta’s hub airports. They will roll out to all other U.S. airports the following week. When it comes time to board, passengers will load into the aircraft from back to front to reduce the number of times they pass by each other. And to encourage social distancing in the skies, Delta previously announced it'll be blocking off select seats in the cabin. The main cabin will be no more than 60 percent full and first class will be blocked at 50 percent capacity.
