Text message from SK for Plus upsell
I don't fly SK often and I'm flying to HKG tomorrow. I got a text message from SK offering paid/points upgrade to Plus. I remember they used to quote prices for them (not that I'm interested) but now they didn't mention about the price, said it's first come first serve. They said if I'm interested I need to go to either check-in or transit counter at CPH.
Just wondering why they don't put a price on the upgrade.
