Love to, but the first aircraft won't be delivered until november later this year with 6 scheduled, the last one being delivered in July 2005.. .. .The boeing (www.boeing.com ?)website will probably tell you more than I can, but I believe the differences are:. .. .1. B777 style cabin interior.. .2. B777 style cockpit. LCDs etc. The current 400s have CRTs. I imagine it would be almost identical to look at as the B777, as are the 737NGs.. .3. MTOW increase to (about) 413,000kg. GE engines as the RB211s do not have the grunt.. .4. Second centre tank for extra fuel.. .. .Rumour is Qantas will be doing (Sydney -)Auckland - Dallas with these, will also enable more payload to be carried on weight limited sectors such as LA - Melbourne.. .. .Don't really know about the cockpit noise reduction. Qantas currently use active noise reduction (ANR) headsets on the 400s, so I wouldn't imagine this would be a big selling point.. .. .Hope this helps. <img border="0" title="" alt="[Razz]" src="tongue.gif" />
