Again, I think you should listen to the advice of Zipp.

Don't use a russian aircraft in the USA. simple

R0 is currently recalculating so many routes that I have to use my phone to access it to stop 9 Air from killing my Xi'an Hub.

It's not a great start when you spell alliance incorrectly...

Terminals increase the amount of gates you can own, without the need to lease each one individually.

World R6 is already a server that only lasts from 2000 to 2030, which is long enough of a server where you can play around with all the new aircraft such as the A320NEO and the Boeing 737 MAX Series. Also I believe that the Boeing 777X isn't in the game until some more specific specifications are revealed to the public.

Hubs allow you to get connecting passengers, which is a useful thing to help fill up seats on heavily competed routes and can easily break the game in very bad ways.

As-well, the doubling of the gate cost will not be a major hassle on your airline once it gets off the ground and you start opening Terminals, so I recommend opening them at the airports you use the most in terms of routes, destinations, and gates.

Shandong Airlines

Even though development for this game is basically non-existent, I would like to see Subsidiaries in the game however I don't think money should be shared between the Parent and Child airlines and rather that the Parent Airlines gives the new "child" airline a starting set of cash and some aircraft so that it can start operations, where it will then operate as it's own airline but it will still have access to "hopefully" the parent airline's hubs, terminals, and connecting passengers as this new child airlines tries to survive in the aviation market. However we probably need other things to be added as-well as we need to answer some important questions on how subsidiaries will work, mainly on if they will be considered a separate airline internally, how many subsidiaries should an airline be allowed to operate, and how should we prevent the feature of subsidiaries from being abused by potential spam-liners.

I Cannot tell if this was done legitimately or if it was a Spam-line, probably both.
