Re: Air China announces 20x A359 order

I wonder if CA bought EY's slots. The delivery date seems to be very early. There was rumors about China-US negotiations on Boeing wide-body purchase. This order seems leave the possibility of a 787-10 and/or 777-9 order open.

Re: Why Boeing hasn’t made a ULH Version of the 787

Even if Boeing increased MTOW to the same 280t as the A359, it would still be fuel volume limited and carry almost 40.000 liters less fuel. Even if your weight number where right, which they are not, and if fuel volume wasnt a problem, which it is, a 260t 787 would at best match the A350 as an ULH ...

Re: Why Boeing hasn’t made a ULH Version of the 787

Did you notice 787 fly PER-LHR at 153t ZFW close to MTOW while A350ULR fly at 167t ZFW not hitting MTOW slightly. A359 DOW is quite a bit heavier than 789 (141t vs 128t). On SIN-EWR the payload should be similar between A359ULR and B789 (254t). The new 260t B789 should be a lot more capable than A3...

Re: Why Boeing hasn’t made a ULH Version of the 787

Because SQ didn't order 787 for that route. Current 254t 787-9 can already fly EWR-SIN with 161 seats. If SQ wishes, they could order some 787-9 now and configure it just like their A350ULR. They already had A350ULR so ULH 787 won't happen.

Re: FG: How are the all-new Airbus (A350) and Boeing (787) widebodies faring?

Safe to say the 787 and A350 families both have a bright future ahead 787 for sure but 350 is in hot water. orders (almost) stop coming in once the first aircraft was delivered. Also reports of performance dissatisfaction are plenty. 350 is a fine plane, too late and too pricey for what it can offer.
