I blame Boeing, they were too busy counting beans to update/replace the 757, and now we will all be subjected to this garbage.
You know it will under perform, even in the article they mention how they will put a fuel tank where paying cargo or bags used to go.
Bumping pax and or cargo so we can cross the Atlantic at 280. With the way the 321 climbs, it will be lucky to make 20 by the entry point West bound out of Ireland. What will they do, enter a holding pattern to climb short of the tracks?
