In a development that marks Amazon’s growing in-house delivery business, the world’s largest online retailer stated, it was on track to deliver 3.5 billion customer packages globally this year.

Amazon’s growing network of delivery trucks, planes, and vans, is considered as potentially a long-term threat to United Parcel Service Inc and FedEx Corp.

FedEx has ended its relationship with Amazon this summer.

UPS however, continues to deliver millions of packages for Amazon.

As per an analysis from Morgan Stanley, Amazon’s logistics delivered around 20% of the company’s packages in 2018 and nearly 46% in 2019 through August.

Analysts from Morgan Stanley estimate, Amazon’s delivery network will ship at least 6.5 billion packages by 2022; more than its estimate for FedEx, at 3.4 billion, and UPS, at 5 billion.

In a statement Amazon said, it has 150 U.S. delivery stations and employs more than 90,000 people.
