Flightwatch, true enough, but there are plenty destinations where we anaway can't make it up to the maximum structural limit, since we are Field limited.
I actually do not have 2 flightplans side by side, but my feeling says it doesn't make a big difference in for example NBO.
On the other hand, the company sold the 400s at a time when cash was needed and they received plenty of it for the deal.
So now it is a situation which is far from ideal, but as far as the official info goes, there were not a lot of options at the time..
