Access report. Went into two of the SEA lounges today -- 75K and MVP traveling to LIR (Costa Rica) on upgraded tickets. AS computers don't seem to be aware yet of Alaska flights to Costa Rica being international. Should get access as Emerald/Sapphire when traveling outside of US, CAN, MEX, but D lounge wouldn't let me in... Had extra time and asked at the C lounge, they agreed with my interpretation and let me in... Even weirder the MVP boarding pass scanned as accepted so who knows what was going on there... Had only been handing them mine on what I thought was a good assumption was that would be the one that worked.

Beyond that C lounge was a nice stop and good to walk some stairs pre-flight.
