Of all Airbus models, I mostly like the A330, in particular the shorter A330-200 variant. Probably it are the underwing fairing and the big wingspan that make the aircraft looking much more mature than the earlier A300 on which it is based.
Honestly spoken, the longer A330-300 is actually too long for being really beautiful, I think, but the -200 has everything in the right proportions. Therefore most pictures on these pages are of the shorter A330-200 variant. The picture above shows an A330-200 flown by the German charter airline LTU.
