Dallas/Fort Worth International Airport (DFW) has committed between $3 billion and $3.5 billion toward the construction of a sixth terminal on airport grounds. The new terminal, slated to open in 2025, will cement a long-term commitment from partner American Airlines.

“Today’s announcement sets the stage for DFW Airport’s next 50 years,” says Sean Donohue, CEO at DFW. “The new Terminal F and the expansion that could follow will provide the region with the growth it needs to compete with international business centers.”

The airline has not shared publicly whether it will be contributing funds toward the new terminal’s construction. “Details will be worked out in the coming months and years,” says spokeswoman Susannah Wesley-Ahlschwede.

The airport is growing fast. In a record year, DFW serviced more than 69.1 million passengers in 2018, up 3 percent from 2017.

The up to $3.5 billion DFW will investing also includes improvements to Terminal C. It will be updated to reflect the improvements made in Terminals A, B and E. The future Terminal F will be located to the south of Terminal D and will include space for up to 24 gates.

“DFW is American’s largest hub and a central gateway to our extensive international and domestic network,” says Doug Parker, the airline’s chairman and CEO. “The plans we’re announcing today will allow for the continued growth of DFW and ensure the airport remains a premier gateway for American for many years to come.”

The two organizations have yet to decide on a layout for the new terminal, but design work will start right away.
