I'm flying LHR-CPH-BKK on SK next month in Business Class.

1. As I am connecting from one 'non-schengen' flight to another, will I need to clear passport control at CPH.

2. Do all 'non-schengen' flights leave from the same area at CPH?

3. Is there a SAS lounge in this transit area, or will I need to clear passport control to access the lounge?

thanks in advance,
AJ
