<---will admit to being a 320 fan IRL - having worked the little beastie for three airlines - Its a jewel to dispatch - it flies farther with much less hassle than the 737 - for a while Transmerdian (US) held the longest fare paying stage length for the 320 (KEF-PTK) only to be userped by SriLankan who ran one from Colombo to Bahrain I believe - ALl the crews I know who have flown them love them once they get into them. And I must admit although Ive never really messed with the 340 there is something about it that brings to mind the 707-320
After the Queen of the Skies you'd get bored watching a 330 doing EVERYTHING for you - of course having watched the loaded Aer Lingus 330s departing DUB for the States - Id be interested to watch the wingflex
