Byrna: As for many companies using the A310/A300 - good for them! I guess they'll wait until a serious accident occurs and then sadly pretend to the press that they made a mistake keeping such old aircraft in service instead of upgrading to, say an A320 series.
How is going from an A300/A310 family aircraft to an A320 family aircraft an "upgrade"? They're completely different classes of aircraft, not least in size. And both families are still in production, so it's not exactly as if one has become obsolete.
