Hi,
That's called a flex weight, so save money on charges based on MTOW.
It seems that weight flex is a smart way to reduce navigation charges especially for aircraft operator with huge fleet of short-haul aircraft. I am wondering if the landing charges is based on actual landing weight and not based on the MLW (Maximum Landing Weight).
Is this permissible in the States? It seems beneficial for airlines especially with short-haul aircraft such Southwest.
Regards
