Interesting anecdote:

I have travel planned in July from JFK-NAP; the inbound served by Air France, flying JFK-CDG, CDG-NAP, but the return was supposed to be Alitalia to CDG, CDG to AMS, and AMS to JFK.

(Why? Well, it was the cheaper and better schedule in J, and I want my huisje and grab a kroket in Amsterdam...)

A few days ago I logged into KLM.com to check something and the entire Alitalia part of the booking had been cancelled. Just, gone. The rebooking was comically bad; it would involve an entire night layover in Milan and there was a smattering of AF flights to get to where I was going.

Rebooked it via the Platinum Service Line to the same deal as the inbound; AF to CDG from NAP. I wonder if the cancellations have something to do with this, as it did have AZ on one ticket with AFKL.
