Not all the A310's are vanishing next year, unless people know otherwise?
I thought the A310's were due to depart gradually between Nov 2011 and 2015. 
I don't think they're all leaving at once, as the current schedules show A310s operating through the summer, but as they're retired some destinations are being dropped.

So looks like
ATH,
DUB,
BCN,
AGP, and
MAD have been loaded, but still no sign of
VIE or anywhere in Portugal (
LIS stops after 2 weekly flights throughout the winter). Still, not too many destinations dropped overall, though some such as
MUC lost most service.
