When compared to other cargo gateways, Dulles, in many ways offers carriers an advantage on airport operating costs. One example is landing fees.
Landing fees are normally charged on a "per thousand pound basis." Of course the fee itself (Dulles's current fee is $3.70 per 1,000 lbs.*) is significant as this charge varies from airport to airport. However, the basis of the charge is important, too.
Air carriers landing at Dulles pay a landing fee based on the Maximum Landing Weight (MLW) of the aircraft. Some other airports base their landing fee on the Maximum Take Off Weight (MTOW). When an example of a B747-400F is used, the MTOW can reach 875,000 lbs vs. a MLW of 652,000 lbs--a difference of 223,000 lbs. This difference can prove to be a significant annual cost saving factor for an airline's bottom line.
