NEW YORK (AP) — Amazon is expanding its airplane fleet, diminishing further its reliance on major delivery services like UPS, FedEx and the U.S. Postal Service.

The Seattle company said today it will lease 10 Boeing 767’s, bringing its total fleet to 50 with the goal of getting orders to people faster and more reliably.

Amazon’s fleet of planes is far smaller than those at UPS and FedEx, which number in the hundreds, but it’s pushed in recent years to close that gap and gain more control over deliveries.

Amazon launched a program over the summer that allows contractors around the country to deliver Amazon packages in vans stamped with the Amazon smile logo.

FedEx CEO Frederick Smith said this week that he didn’t see Amazon Air as a competitor, but a number of industry watchers disagree.
