I think a lot of the problems 'highlighted' by some at the start are slowly disappearing, as load factors have risen and some airlines can make good money now. I think the slower speed of the aircraft and the time it takes RI and marketing to develop is excellent, as it acts as a natural brake for airline growth. Marketing would have been less influential 60 years ago and passengers that flew would have paid more attention to comfort and seating due to their higher social status. Whether this was intended or not, I don't know, but if it was then its a great tweak
I totally agree with Daveos here. In real world, airlines run a route 6 month befor deciding if it is profitable or not. So, LF around 30 % the first month is something we should deal with, especially when the airline just started operations. This might be hard for new players but could be balanced with an increased start capital.
With Bug Report Airline (http://www.airwaysim.com/game/Info/Others/Airline68
) I ignored fleet comonality and checked out 5 different fleet types(C-47, DC 6B, DC 4, B-377, Martin 4-0-4).
All types are profitable, even longhaul routes using a 2nd leg and both legs using the maximum range of aircraft(with technical stop/fuel only). E.g. New Delhi-Technical Stop-LHR with DC 6B or Dehli-Technical Stop-Seoul with Martin 4-0-4 are money makers.
As mentioned before, a 3rd leg would be fine to do things like: LHR-Techn. Stop-Techn. Stop-Tokyo in a "50ies and 60ies only" scenario.
Due to the long flight times, a reconfiguration (I mean reduction of capacity, HD to Standard conf. and adding C&F) of the planes is mostly needed to increase LF.
So the factory default configs are mostly not newbie-friendly.(I´m based in Delhi, the next destination are 400NM+ away, might be different in Central Europe).
Compare to an 80ies scenario where a B737-300 in default config Y126 can be put on (nearly) EVERY route.
All in all I would say it is easy to make money in this game. One reason might be that fuel is very cheap an fuel costs don´t play a major role compared to other game worlds.
For experienced players it is a new experience and should work fine, but for new players it might be difficult to get the foot in the game because route planning is more tricky and limited to LF´s.
