11 hours and 10 minutes. A friend from Beijing is visiting Los Angeles. She is flying on Asiana Airlines, and they transit through Inchon/Seoul. This second leg of the trip takes about eleven hours, and the plane is about to land in a few minutes.

I used to travel to Asia often about twelve years ago. The flights were long but did not seem onerous. I do not know if I can survive that long in an airplane anymore.

I received a WeChat text that my friend has arrived at LAX but nothing for the past three hours. Hopefully she is not stuck in immigration or customs.
