Yeah, CPH-DOH-SIN r/t is still available for approx EUR 1020 (incl. MASTERCARD promo). Travel before 21 June. Bookable until midnight today. A busines class fare to Asia - unfortunately, I can't travel/use it now. Hopefully, it will be repeated another time.
One thing you can be almost certain about with Qatar - it WILL be repeated.
I'm waiting for a sale from scandi to asia for travel in March. I'd bet money on it there will be a similar sale in a few months time.
