Indeed quite ironic.
KLM ordered the A310 way back in the eighties, mainly for their cargo capacity. They replaced the A310 by the 767 because the 767 had much better range. Then they found out that the 767 cargo capacity was quite disappointing. And now they are replacing the 767 by the A330 because the 767 doesn't have the cargo capacity!
The 777/330 combination is getting quite popular these days!
