Thanks CPH-Flyer. Two days of trying - website won't take my passport details or Hubby's. Cannot select seat for our return leg. Totally unimpressed. I downloaded the App and was able to have the passport details saved. But still no luck with App on seat selection for return leg of journey. I hope the website/App unreliability is not indicative of what I can expect on SAS.
I am an elite flyer with Cathay Pacific. Their website is also quirky at times, but it has never totally failed me on multiple attempts. No excuse for this really. SAS - are you listening????
