American announced a bunch of new routes this week, but one caught my eye. The airline, which flies only to Beijing, Shanghai, and Tokyo in Asia, will now start a flight from Dallas/Ft Worth to Seoul. American doesn’t have a Korean partner, so it will be largely traffic destined only for Seoul. I’m sure Latin has something to do with this – after all, the flight connects perfectly with the new Dallas-Lima flight, but DFW is far from being a huge Latin connecting point for American. That’s what Miami is for except for Mexico flying. So what is it? I’m sure it’s some corporate arrangement or something that makes this work, because otherwise I can’t figure out why Seoul would be American’s next Asian move.
