As a Pilot you have two choices: If you are lucky an Airline will pay for your training and then expect a return of service or training bond equal or above the cost of the licence.

However as the B747 Classics become less popular with the major airlines and more prevalent in start-up and smaller cargo operators they will expect you to pay for the training before you are signed up.  This "Self-Sponsor" route offers you the freedom to leave at anytime subject to contract without a financial penalty to seek higher paid employment elsewhere after gaining experience and hours on type. 

After your initial Type Rating you will need Base Training, normally three take offs and landings in the actual aircraft to remove any restrictions on your licence.  This is then followed by Line Training, typically 100 hours with a Training Captain.
