Glad to see this was brought to the live site.
However, I accepted a schedule change this morning back from BKK. Both of my domestic segments (SEA-ORD, ORD-CVG) did have the up arrow on the preview site, but after accepting the change, it came off of the SEA-ORD segment. That segment also had an aircraft/flight number change (Went from PMUA to PMCO). Seat maps not available for all my flights home - agent thinks this might have to do with the seat map issue that they are apparently still having. Will have to deal with it if the arrow still doesn't show and I can get the seat maps working again.
