That's an interesting point.
Are you certain that cargo distributes the same way as pax? I currently have no competitor flying 757F long-haul to compete in my 777F routes. Also, does tech-stop affect cargo the same way it affects passengers? If so, 777F might have an advantage in that it has longer range than other freighters. I can fly to the west coast of US and some EU countries from Japan in my 777F without a tech-stop. Most if not all destinations in the world can be done with a single tech-stop.
Cargo is not very sensitive to tech stops, but I will post here. GW3 is about to get 777F.
If my assumption is correct, that tech stop does not make a material difference in cargo, then when comparing 2x 757F vs. 1x 777F on an oversupplied route, The result we will most likely get is:
- Revenue: 200% in favor of 2x 757. May be a little less than 200% (2 flight vs. 1), but much closer to 200% than to 75% the capacity would suggest (102,000 kg vs. 78,000 kg)
- Landing fees: single 777F is 50% more than 2x 757F
- Handling fees: single 777F is about 25% less than 2x 757F
- Ground handling: is per kg
- Pilots: 4x Large positions vs. 2x Very Large positions. But the system allocates a multiple for each position, and the multiple differs. Large may be 8 per position, Very Large may be 12 per position. Salary is also significantly different. My guess is that 2x 757F is slightly cheaper than 1x777F
Summary:
- 2x 757F will give you 2x Revenue at approximately the same (or lower) cost on a heavily oversupplied route.
- 777F is great in a sandbox, likely very bad in a competitive situation
- 757F is great in a competitive world, good in a sandbox, much quicker to turn profit on a new route
