With the 777-8 five years away, we compare the A350-1000 to the present 777, the -300ER. The changed fuel prices create a different yardstick since our last comparison of the 777-300ER and A350-1000.
While at it, we also check how much better the A350-1000 score on costs versus the smaller A350-900.
The A350-1000 is the most efficient aircraft of the three.
The A350-900 is smaller. It has Cash Operating Costs per seat mile which are close to the A350-1000.
The 777-300ER is the most expensive to operate, also at today's fuel prices. Pricing must be very aggressive to compensate operating cost differences to the A350-1000.
With A350-1000 deliveries starting, the 777-300ER's reign as the twin to have for 350-seat long range is ending.
