Amazon set to expand drone delivery of lightweight packages to 500 US cities

Millions more people may be able to get smaller, lightweight Amazon packages delivered by drones by the end of the year under a plan the company announced Wednesday to expand the airborne shipping to suburban areas in nearly 500 U.S. cities.

Customers could receive the drone deliveries in as fast as 30 minutes, Amazon said in a news release. The drones can carry packages up to 5 pounds.

The plan will intensify the battle between Amazon and Walmart to provide consumers with the fastest delivery times. Both giants rely on a mix of drones and drivers to deliver everything consumers have ordered.
