Looks more than likely we'll have to fly via CPH both ways to/from ARN this summer now (currently just the return flight to the US has been changed to ARN-CPH-EWR). I just hope Denmark relaxes their 24-hour requirement for negative test if you have proof of vaccination; maybe make it 72-hour. It certainly would reduce the stress of finding a testing site in the middle of nowhere Sweden.

Edited to add: I would hope anyone not eligible for a vaccine (those under 16 years old) would also be allowed the 72-hour requirement.
