Yeah, great intro fares TO Nagoya if you originate in the States. For those of us who live in Asia, we'd love an intro fare to fly TO the States from Nagoya. Cheapest that the AA agent could offer NGO-STL-NGO was about US$900, while it was many hundreds of dollars cheaper STL-NGO-STL.

Based in TPE, I usually take CX to NRT to connect onward on AA. However, CX has a daily TPE-NGO flight, the schedule of which to and from NGO fits absolutely perfectly to connect up with the AA NGO flight to and from ORD.
