I have to say, having travelled SK for the first time last month DUB-CPH-BKK that as a BD*G I was treated with absolute indifference.
I couldn't get the seats I requested (which turned out to be empty) and was lumped in a middle seat. I asked about an upgrade to E+ and was glared at. I asked about using miles and was given a very rude answer (which made me lodge a complaint - the first in 10 years of travelling).
Apart from this, the service on board was very nice, though leg room was an issue.
