If the 777 is that much less efficient than the A350, how is Boeing still selling them? What am i missing here?
One needs to consider ownership costs (maintenance etc.) balanced against re-sale values per aircraft model.
I got a car I would like to sell you cheap so I can afford my new car with no real maintenance costs, yet, and it also gets 20% better mileages.
Act now! don't let it go, fully guaranteed until next scheduled maintenance (which is next month) and requires removal of the engine for an update
