Amazon Slumps on Logistics Concerns as Prime Big Deal Days Loom

Amazon's shares dropped nearly 2% on Tuesday to $248.73 after the company paused air cargo operations with 21 Air following a fatal crash involving the cargo carrier.

The move put Amazon's logistics network back in focus, which is central to its retail promise.

Air cargo flights are crucial for Amazon's delivery network, and the pause drew attention because fast shipping is a major part of the Prime membership pitch.
