Bugs on AS site are just frustrating.
Finally was able to book SEA-DXB-AMS-DXB-SEA-PDX. Adding in PDX at the front end resulted in routings through LAX or SFO. Tossed in the return SEA-PDX just for fun and was surprised to see it didn't change any routings or availability.
Tried to get the partner desk to add on PDX-SEA and was told they can no longer do this, has to be available on the web site. Hung up and tried two other times with the same result.
I'll have to figure out how to maximize chauffeur drive in this situation, maybe dropping the final SEA-PDX leg.
