As long as Mx schedules are carried out on time,An old Aircraft is as good as a New one in terms of Reliability.However with passage of time,due numerous of Checks Increasing & Frequency of those checks more Frequent,to add that component replacements are called for earlier,this all leads to Expenditure which an operator would like to avoid.Hence its easier to work on New craft.

Its a balance & desicion taken by the operator at the time.

Also some Manufacturers use the carrot & stick policy.Where replacement of a particuar component on a craft will be called for frequently leading to expenditure & an offer of Buy back old craft & sell a Discounted new craft will be madfe to the operator which gets tempting
