On the 9-21 SJC-TPE flight, one of the flight attendants told a bunch of us FT'ers that the route was being cancelled, and that she got the word on that day. A very sad time, especially since part of the crew for that route will be laid off.
Personally, it's also a problem since I have another trip booked for Oct. 19th. I guess AA will end up routing me through NRT.
