Home base income statement

[logaritm]

So i'm a beginner and when gameworld 2 started i chose to start in a relatively small airport, now ~15 years into the game the majority of my airline operate at the capital and my base airport operate some old routes from the beginning.

Anyway, i was looking into the income statement of my airports and after closing one i found out that my base airport operated at a confusingly high loss. Even when subtracting the marketing costs my base airport still stood out with the biggest contributor being the aircraft maintenance. When compared to one of my other airports which operates 5 times as many aircraft's of the same type the total maintenance cost does not make sense, i can understand it being higher per plane but not at a total cost of several degrees.

My guess is that the base airport cost also contain the maintenance cost of other airport like their total C maintenance, which would be kinda annoying since i'm trying to calculate some stuff

HQ airport is the only one that shows: Training Cost, Marketing, Alliance Fees and Fines. It can be very easy to happen if your HQ base is a very small part of your business. It is not helped by the fact your margin is low single figures and low aircraft utilisation. Your overall cost base for your airline is also very high, about 3.63 Cents per ASK, which is more than double that of mine. So increasing utilisation will lower that, as will reducing other costs such as marketing and leases.
