Just a quick comment about what is included where, the big one that should probably move is lease payment from capital expenditure to just being a regular expense, component of the net operating income.
Another comment, and this is just a general comment, it is great to have a cashflow statement, but as far as accounting is concerned, it is a distant 3rd most important item behind Income Statement and Balance Sheet.
Another idea: Since, in effect, AWS is simulating management of an airline that is publically owned, and publically owned airlines publish their quarterly reports, perhaps we should also have the Income Statement and a Balance Sheet (once they are done) of the other airlines publically available for other players to see...
What you say is true for financial accounting. But, we are running the airlines, so our need is more balanced toward management/cost accounting reports.
There is a difference between financial accounting (which the i/s, b/s, and cf statements are geared towards), and reports used internally for managing an entity. The audience for financial accounting is largely external to the operation. http://en.wikipedia.org/wiki/Comparison_of_management_accounting_and_financial_accounting
Of the three statements, the cashflow one might actually be the most beneficial for running our airlines.
Having reviewed the one sami linked to, it is pretty good. I have a delta with what I was calculating independently, but I did not spend much time analyzing it - I'm probably missing something
It is much easier now to see what your operations are contributing to your airline's health. It will probably make it clearer the importance of liquidity and help players make better decisions on investments with their cash flow impact. From this statement, all kinds of interesting metrics can be made to help one manage their airline.
The income statement will probably be more important in understanding the basis for taxation. Would/will be nice to see depreciation and amortization rolled into it and to see the smoothing effects on tax. This will likely take a big bite out of the year end tax purchases of aircraft - they will then spread more evenly through the game year.
The balance sheet might be the least useful, except as a "score card" where the equity account would indicate how much "wealth" is being created by the airline.
But that triggers a thought...maybe I missed it, but won't this all ultimately impact the credit rating too? The balance sheet would be very much part of that assessment from a "credit ratings agency".
