It found American and Delta/Northwest had the oldest fleets, at about 16 years on average. As of the end of 2008, a small percentage of the【D3】______ Delta/Northwest’s planes dated back to the late 1960s. U.S. fleets are among the oldest in the world, said Richard Aboulafia, an【D4】______ analyst.

It’s also important to remember that a plane may be 20 years old, but its engines and other major systems could have been recently【D7】______ or upgraded, said Aboulafia.
