Why not kill the idea all together? 737-400 are going to lose you money anyways. The game engine is doing you a favor.
734 is to 738 as Commodore 64 is to modern Desktop
Sorry to disappoint you, but for the number of passenters that a 734 carries, it is quite capable of being a profitable airliner up through the end of the MT era. Of course, the NG series is better due to the availability of the 900 without incurring commonality costs, but since you're comparing a specific plane and making a generalized statement about losing money with a perfectly good plane....
Nice comparison, Nico!!
He is right, in MT you won't succeed if you don't use 736/8/9 (not the -700, that is bad as well) or A320family for your Short Hauls!!
The 736 is worse than the 700.
How about the MD-80's???
Not a great choice in MT. I'm personally a fan of the M90s, but they only work in certain geographies (i.e. transcon range is limited in the US - you've got to be centrally located to use them effectively). Also, the inability to upgauge them with common types can be a limitation.
