Aircraft lifespan is usually measured in the number of (takeoff and landing) cycles. A shorthaul aircraft will therefore rack up cycles much faster than a longhaul aircraft. Except in some cases where there is massive demand on short routes - mostly in Asia - it rarely makes sense to put your biggest, most expensive aircraft on such a regime which prematurely "ages" it.
