Amazon is building a regional air hub at Fort Worth’s Alliance Airport, bolstering its shipping business in a move that’s expected to create hundreds of jobs for the region.

Amazon announced Tuesday that construction is underway on the facility on the west side of the airport, with operations expected to begin next year. The hub will support multiple daily flights and infrastructure for sorting packages, Amazon said.

Specific details, including the size of Amazon's new facility, were not disclosed Tuesday.

Amazon’s arrival is the latest win for Alliance Airport, an industrial and cargo-focused airport that's entering a new phase of growth after nearly 30 years of operations.

"If you think back to the original vision of the airport ... with it being an industrial airport focused on aviation, maintenance, manufacturing and air cargo, it fits that," said Tom Harris, president of Alliance Air/Aviation Services, which operates and manages the city-owned airport.

Harris said Alliance offers freight shippers all the major airport amenities, including a Federal Aviation Administration control tower and U.S. Customs and Border Protections screening, without the hassle of having to share runways with passenger aircraft.

This summer, the airport completed a $260 million project to extend its runways, allowing for more consistent operations, especially in hot weather, for fully-loaded, large cargo jets.

The airport is already home to a major FedEx shipping operation, with as many as 30 flights a day. The airport sees an average of about 300 takeoffs and landings per day, with a mix of business jet, military, cargo and general aviation traffic.

For Amazon, the Alliance hub is its latest step toward building out its own air shipping network to supplement services provided by UPS, FedEx and the U.S. Postal Service.

The Seattle-based retail giant has acquired a fleet that's expected to number 40 aircraft by the end of 2018. It's in the process of building out a central air shipping hub at Cincinnati/Northern Kentucky International Airport at a cost of $1.4 billion that's expected to create more than 2,000 jobs.

"We are excited to build a brand-new facility from the ground up at the Fort Worth Alliance Airport," Amazon Air director Sarah Rhoads said in a statement. "The new facility is the first of its kind for us and we're thrilled to ensure we have the capacity to continue to delight our customers."

The airport is part of the massive AllianceTexas development. The 26,000-acre project has nearly 50,000 workers, 44 million square feet of development and over $8 billion in private investment. The development also is home to an Amazon fulfillment center.

Harris said even after Amazon's arrival, the area directly surrounding the airport will only be about 50 percent built out, with plenty of room to accommodate additional aircraft traffic well into the future.

"We still have quite a ways to go," Harris said. "When you think purely about aviation and aerospace companies that want to move to Alliance, the number of prospects has never been this strong in my 29 years of being at Alliance."
