All depends on the airline, my airline, which I retired from and have free flights on for life flies 320/319, no problem, I'm no fan of the A300 or the A300-600, but the A330 is a joy to be a passenger on.
I don't care for the MD-11, a crappy plane, poorly built and thankfully being used for cargo mostly.
I havn't been on an A330 yet, so I'll withhold judgement on that one, but I agree about the older ones... and the MD-11? Yuck.
I guess I'll wait and see how good of a plane the combined wealth of the european countries can really build ;0)
Can you give me any instances of what exactly was "poorly built" about the MD-11's? All of the structure down to the frames, windows and skins belongs (built/designed)to MDC and Boeing - all other interior items such as lighting, tvs, seats, carpets lavs, etc. belong to the airline because they choose the way the interiors are finished. In many cases, the interiors are not even completed by the manufacturer but by an aftermarket mod shop specialing in just interiors.
I bet your gripe has to do with the airline's portion and not the manufacturer's end of the business, right?
