I'm booked SK958 MIA-ARN on November 9. My flight MIA-CPH-ARN on November 8 was cancelled. I do not know where the air craft is coming from since there are no flights booked between Scandinavia and Miami on November 9. Maybe a cargo flight coming in??
Unless it has changed recently, Americans can't enter Sweden from the United States unless they live in Europe. It is necessary to transit through a different Schengen member state. While MIA-CPH-ARN (entry from Denmark) is permitted, MIA-ARN (entry from the United States) is not. Are you able to enter under one of the very few exemptions, or are you a European citizen?
