RED ROCK, AZ (3 TV / CBS 5) -- Several commercial jetliners, mainly from Delta Airlines, landed at Pinal Airpark Monday.

According to the aircraft tracking app FlightAware, the first flight landed around 7 a.m. Monday morning from Minneapolis. There have also been Delta flights from Atlanta, Detroit, and New York City, an Aer Lingus flight from Bangor, Maine, and an Air Canada Flight from Montreal.

Pinal County Airpark manager Jim Petty says all this increased activity is because airlines are cutting flights due to the spread of the coronavirus and need a place to park their planes.

"Of course what's happening in the short term is sad because it's got a lot of negative economic repercussions for the world, and it's preventing people from visiting people," Petty said. "But I think this is a good reaction to the situation."

Petty says airlines often choose to store airplanes in the Southwest because the dry conditions help preserve the aircraft. Once an airplane is parked, the engine is often sealed up to keep dirt and animals out, and the windows are covered with reflective shields, so the sun doesn't damage the equipment inside.
