the Il-86 being one of the few with almost zero applications due to that range and when it comes out
. In domestic usage it will usually be over capacity or get frequency bombed
Although tbh this game is about fit and trade offs. If you go western you better have lots of money already in the bank or you will be leasing and between leasing western and buying soviet it can be a wash or close enough depending on fuel costs. But if you can afford to own, not lease, either western or soviet(using large order discount and 100% upfront payments if possible) then Western types are clearly better. Another difference being in general keeping soviet aircrafts for a long time can sometimes not be viable due to maintenance costs while for western types it still works very well comparatively.
Almost the same could be said of popular/unpopular air-frames as while they may be justifiably unpopular the cost band availability delta can often times tip the scales, see MD-11 vs A330 or B767 the latter two of which can easily cost more then a 747.....think about that. The same thing repeats itself latter where 773ER, A350 and even 787 cost more then A380 or B748 in GW3. So in those circumstances if you can fill the MD-11 or latter the B748 or A380 then it would not only cost less but also be more fuel efficient (pax/kg of fuel) in some cases for the latter two.
For smaller types.... If you had very short range flights with medium demand you could of gone for the Dassault Mercure at only 820NM (GW2, was lower in GW4)max range but was very cheap and fuel efficient. And the DC-9 is somewhat better on GW2 than the 1-11 if you were late to the game to the 1-11 or needed to do later follow up orders as it is both cheaper and available, with the tu-134 not being a terrible alternative due to very low capital costs (1/3 of DC-9 and 1/5 of 1-11 when no one orders it).
At start up you could of gobbled cheap C46's, Il14P's , B170's or DC3's and made a killing (chose only one
). They only real advantage of the longer range aircrafts is for slots and if there was no competition.
1. Dont expand too fast or in congested markets,
2. Stick to low amounts of fleet types, especially early
3. review default prices often
4. Have good scheduling (especially 7 days)
5. Have fleet types which make sense for your location, no need for 747-100 in 100 pax long range markets or 772LR in continental markets (extreme examples) but also no need for having 737-800, A321 and 757-200 in same airline in this game, even if it might work out IRL.
6. Own instead of Lease if you can afford it. Even if soviet
