On March 31, I made a reservation on Delta for a flight from Salt Lake City to PDX as a part of a round trip flight-- to SLC on Alaska the 12th of July and the return on Delta at about 5 pm on July 16th. A short time later, I received an email stating that my flight had been canceled due to covid 19. It was not obvious that the canceled flight canceled User's recommendation: Do not make reservations on Delta.
