In 2013, I was in Tokyo at the start of the DONE3, when on the way to HND for the first flight, Typhoon Wipha caused most ground transport to halt, causing a late arrival at the airport and missed check in. There were 3 other people on my train heading for the same flight and upon arrival at HND, CX rebooked the flights.
I was flying HND-HKG-JFK.
I had an separate JFK-BOS flight on AA the following morning after planned arrival (8 hour overnight connection). CX rebooked me on to the afternoon HND-HKG, then onto CX888 to JFK via YVR. This change then cut the planned overnight connection to AA down to below JFK I-D MCT.
At the time, AA was still operating their HND-JFK night flights. That day, their flight to JFK had been delayed due to the weather so the AA desk was still open. After getting the CX flights sorted out, I went to the AA counter to sort out the JFK-BOS issue.
After explaining the problem, they quickly moved me to the next JFK-BOS flight.

With this policy change, would AA no longer do the same in a similar situation?
