The 767-ER is now Super Premium
Qantas reports the empty weight of the 787-8 is now more than 102 tonnes compared to specification of 94.5 tonnes. The good news that the GEnx they chose is only off the SFC target by "only" 3% compared to 4+% off for the R-R, which needs to redesign the first stage compressor which may cause it to be removed as a flight test engine.
The combination of higher fuel consumption and higher empty weight means 787-8 performance for the production units originally envisaged for Qantas will under-perform a 767-300ER. The report discloses significant redesigns for later -8s and the -9 are in work, placing those delivery schedules in jeopardy
