Alright, so I have 100 RI on my route to Tokyo Narita and I want to do a couple of cargo routes. I am torn between 2 aircraft, the 747-800F and the 777 Freighter. The 747 holds close to 300k lbs of cargo, and the 777 holds close to 225k lbs. The 747 burns about 2,000 more fuel than the 777, and has less range. I already have a few long haul 777 in my fleet. Should I just stick with the 777, or would the increased cargo capacity of the 747 offset my costs enough to make it worth it?
