Ah yes, Hansol and the "big bank account" theory. Every heard of liabilities Hansol?
A simple glance at the latest quarterly report shows that shareholders equity actually DECREASED for the quarter.
Furthermore, Ryanair's operating margin on its core business - flying people from A to B is decreasing. Its a bit over 22 million. It was 25 million last comparable quarter, even though revenues are up about 88 million.
As for maintenance costs - they are constant at about 14 million. With 96 aircraft and 14 bases.
This sounds a bit light to me because way back in about 1984, with a fleet of approximately this size of mixed aircraft types, admittedly with a heavy maintenance program going as well and about 1100 staff in maintenance my annual maintenance budget that was accepted was $110 million - thats 1984 Oz dollars.
I will leave the rest to your imagination.
