Got an email this AM from JL. JL5 JFK-NRT delayed for tomorrow by 3:15 to depart now at 16:30. But it sounds like that might change again from the above post.

Thank goodness for the notification so I was able to re-route via HKG to SIN. Since I would be missing the connection due to the delay AA didn't charge me anything to make the switch. But I did have to ping-pong back and forth with AA telling me to contact JL and JL telling me that AA had to make any changes. But it seemed like the place JL transferred me to at AA was one of their better agents as she was quickly able to accommodate me. (I'd already checked award availability and saw an open F seat on CX.) Ultimately it works better for me all the way around.

Best of luck to all of you in Japan.
