I'm looking at flights in August from ARN to New York on Expedia. I noticed a pretty good SK fare in K class (which only earns x.25 miles in BD diamond club). Anyhow I don't really need the miles at the moment so decided to click through and check out the seat map. Strangely it shows the Economy Extra seat map (rows 14-18 with 2-3-2 config) and allows you to choose seats there. Now if I book it I assume I'll soon be reassigned to Y? Has anyone else seen this error before?
