Theyll have no idea what they paid Boeing for each 737 etc...
Ryanair's financail report says the list price of the last order was 78 million $/aircraft + 2,9 million /aircraft for "buyer finished" equipment - "allowances" from Boeing.
Final price of the 175 a/c was 13,8 billion $ which means approx 78,8 million $/aircraft. Surely they don't lie in their financial reports, I quess.
