Well I did have a large airline using the Il-96 as a mainstay of the fleet. Had over 150 of those babies
. Granted many people helped me acquire those planes as the production rate was quite slow.
Could I have made more money using 767's instead? Hell Yes! Did I go Bankrupt? Nope. But when I did that I had already attained a monopoly on South Korea (funnily enough I killed my then biggest competitor by frequency bombing them with the VFW-614
That game world I started with VFW-614s and Dassault Mercures (Basically only domestic and limited regional). Then added DC-8s in the late 70's. Then got 767's and by then only had the 767 and VFW-614s iirc. Added the 747-400 and was quite bored of the 767 (-200ER) so I sold all of them (80 ish) and went for the Il-96-300 (before the recent buff), got rid of those ASAP with the Il-96M (2 vs 3 crew, much better CASM) and stuck with the Ms for the most part till the end of the game world in 2020. I had some Il-96-400s but in that game world they had very little range and could barely go anywhere.
Anyways, I ended up replacing the 747-400s with a boring choice, the 777-300ER and then added some ULH with the 777-200LR and even up gauged some early Il-96 routes which had grown quite a bit to the 777-300ER. Also dropped the VFW-614 as they got old and I had no more competition (some tried later on, I prevailed) so I went with the 757 domestically (757-300) and built a small regional fleet of those.
Ended up with 40 ish 757s, 150 ish Il-96s (all except 35 of which were Ms) and 150 777s. I was top 20 in many categories, even for profits.
