Don't want to start a Airbus vs Boeing debate but when we last flew to New Zealand with Emirates, the first leg was Boeing 777 from LHR - Dubai then A340 from Bubai - Christchurch. No comparison between the two - the A340 was just great - plenty of room (in econmomy) and very quiet and comfortable - not so the 777 unfortunately. Yes - very lazy climb out but as someone said - probably a 'flex' take off. The sunrise/sunset lighting was a real treat to watch.
