I used to play Miller's AE but this is my first go at Yuxi's.
With the bottleneck in aircraft production lines, it seems the fast expanding airlines need to lease less efficient types. I'm in S1 and it's 1996 right now.
Let's use the 747-400 as an example (but there are worse, of course). Seats 660 but guzzles approx 70,000 fuel and the lease costs $2 million a month. The aircraft seems only viable on trunk routes where overcapacity and lowering margins are already taking effect.
Does overcapcity get so bad that you're in danger of making less than your lease/maintenance/gate slot costs with the 747?
Another example is the Il-96. Dirt cheap, seats 300, but guzzles 55,000 fuel. How would this aircraft fare?
