Byrna: As for Globaliser asking why Airbus is still making new A300/310's - I don't know the reason except perhaps cost benefits (cheaper to build and operate an A300/A310 versus an A330 perhaps?). Would YOU care to suggest a reason?
Because they're not obsolete and they're not unsafe. And certainly not enough of either to warrant a passenger carrier throwing them out like last night's takeaway curry, as you'd seem to want them to do. That's all.
