But age is not necessarily a factor if an aircraft is properly maintained.

The current Air Force One 747s have less than 30 years service and they are the most well maintained planes in the world, so maintained that a part gets replaced at the first sign of wear and tear. And they still fly less miles than a commercial airliner.

And the Air Force is still getting rid of them for new 747s that will be available sometime after 2020.
