I flew Delta from SFO to ATL last week. No food or alcohol sales on any flights. No middle seats are occupied to create extra space. Masks required everywhere in the airport and during the entire flight. If my temperature was checked anywhere I missed it. I was sort of expecting that to happen at the security checkpoint, but as far as I could tell no one was checking temperatures. For the time being there are less flights available and fewer seats occupied during the flights. I noticed the flight path was different than normal, about 150 miles shorter and 40 minutes shorter travel time. Might be because there are less planes in the air.
