Over at QF, aircraft were more or less the same, as long as they were optioned exactly the same way. There was a large difference between 767/200 and 300, and also between 300GE and 300RR. Jumbos had the same sort of difference. The -400 was dramatically more frugal than the -300, and there was quite a difference between the RR and GE aircraft. Over on the 380 there was no noticeable difference. But, at the flight planning level, each aircraft had a different treatment, with a percent or two variation across the fleet; not necessarily new vs older though.
All of the 747s were bent...except for OJH. Go figure.Even on the 777 I didn’t notice, unless you flew VPD which, unless you centred the control column, flew crooked and so the fuel burn was higher.
