Airliners.net is reporting that KLM will fly the/a A330 to MIA in Summer 2012.

Article

The original poster on Airliners.net is actually a bit late to discover that. (and always late to discover whatever that's been changed)

I posted an update on my site on 29JUL11, but I didn't bother to post it here anyways. (The poster probably "discovered" my post few days later otherwise no one bothers to check June/July 2012 schedule right now in Aug 2011)

MIA goes 332 from 01JUL12.

DAR/JRO mix of 772 and 77W from 01JUL12 (I didn't edit this one in the post)

YYC Increase to 6 weekly from 06JUL12

PTY stays at 6 weekly but will still see 772 replace M11

Seems some MD11 destinations are coming to an end.

You mean that they will no longer be serviced by the MD11, or they will no longer be serviced at all?

Serviced by the MD11.
