Maybe they should have a word with SWISS.

One or both of the longhauls in my upcoming trip were rescheduled by some trivial amount, but that alone was enough for me to explore their "chat" (in a browser, not over the phone) to view all rebooking options.

As I had a rather tight connection in ZRH on the way back, I took an option on a different airline completely with a more resilient connection. The whole thing worked rather well.
