Debatable, given alcohol prices at places like Oslo airport (EUR 18/GBP 15 for a glass of wine is sort of standard), probably considerably cheaper to get your buzz on at the SK lounge. Yeah, the quality of SK lounge alcohol is nothing to write home about. OTOH, I'm not exactly happy to shell out EUR 60 for two beers each for two persons (if I pick up the tab).
Also, while they're lounges are far from great, overall, they're still on the same level as LH SEN, I would argue.

Overall, I am happy I'm a free agent and not married to *A. These days, the alliance that's gaining strength is OW.
