I'm trying to check in online for NRT - TPE tomorrow evening, and the message above pops up. My booking comes up on the site, but not able to check in. The seatmap on UA's site shows the eco cabin as almost full, but Flightstats shows alot of availability. Could this mean a possible upgrade? I'm SK*G. I'm not planning on contacting Widerøe (where I bought the ticket), because it's a sunday, so they probably won't be able to reply on time anyway. Thanks for any replies.
