Sometimes it's even hard to book SK-flights using SK's own website...
I wanted to book a oneway ARN-CPH-OTP (Bucharest) on May 1st but "Romania" isn't an option using sas.se - even though SAS has its own flights CPH-OTP! I then checked sas.dk and "Romania" is avialable. I was able to get the following pricing:
Scandinavian Airlines
SK 1417 ARN 07:10 - CPH 08:25 Non-stop / 738
Scandinavian Airlines
SK 1781 CPH 09:20 - OTP 12:50 Non-stop / 319
Prissætning af rejsen
Billetpris Skatter Salgstillæg DKK
1100.00 + 205.00 + 75.00 x 1 Voksen = 1380.00
SK 1417 KSEOWM
SK 1781 KSEOWM
I talked to SAS Internet support because I wanted a price in SEK, not DKK, and because the fee at sas.se is 50 SEK instead of the 75 DKK at sas.dk, but I got the answer "SAS does not fly to Bucharest". After replying that "Well according to sas.dk SAS do fly, flight no. is SK 1781 CPH-OTP" SAS Internet support just answered "Well book it on sas.dk then..."
