Standard deal when buying a new airliner would include X number of ratings provided per aircraft.
Er.......... not quite. it is a customer option, "we will train five crews per aircraft" etc. Or, we will provide a better galley, a better set of airstairs, an improved interior, or any number of add on options the customer would like. Crew training is not a standard deal at all but if the customer is a new one, new to the aircraft, then the manufacturer would always hope they took their training from them and may even make it conditional, (Airbus).
