Officials have unveiled plans for a major expansion at Miami International Airport, where a $1 billion project will expand Concourse D and add new gates to support growing passenger traffic.
The announcement was made by Daniella Levine Cava alongside Robert Isom, who confirmed that crews will soon begin work on the airport upgrade.
The project centers on the three-level Gate D60 expansion, which will add 17 new aircraft gates along with adjoining passenger boarding areas. The development is part of a larger infrastructure initiative designed to modernize the airport and improve operations.
The expansion is included in the airport’s $9 billion Modernization in Action Plan, a 10-year capital improvement strategy focused on upgrading facilities and expanding capacity. Other projects within the program include a $600 million Concourse K development and a $745 million redevelopment of the Central Terminal.
The Concourse D expansion marks another step in the airport’s long-term modernization push as passenger traffic continues to rise. American Airlines, which operates the majority of flights at the airport, has also announced plans to operate its largest summer flight schedule ever this year.
Currently, Concourse D primarily accommodates smaller regional aircraft. The upgrade will eliminate outside boarding and create 17 full-service gates capable of handling larger planes.
The project will also introduce a new baggage handling system and provide direct third-level access to the airport’s U.S. Customs and Border Protection facility, improving the experience for international arrivals.
“The D60 expansion is one of the most monumental customer service improvements within our unprecedented airport-wide modernization plan, which will transform the passenger experience at MIA from the cabin to the curb over the next five years,” said Levine Cava in the release. “MIA ranks among the fastest-growing global hubs since the pandemic.”
In addition to the new gates, the project will redesign boarding areas. Instead of one shared boarding space, the upgraded concourse will feature adjoining boarding areas for each gate, helping improve passenger flow and providing additional space.
Airport officials and airline executives say the project is essential for supporting future travel demand in South Florida.
American Airlines currently accounts for more than 60% of passenger traffic at Miami International Airport and operates roughly 400 daily departures from the hub. Company leaders say the expansion will help the airline sustain its growth in the region.
“Miami is an important hub and gateway for American, and it’s an essential part of our history and our future,” said Isom in the Feb. 25 MIA release. “The brand new, reimagined D60 is a transformational project that will provide a much-improved experience for our customers and our team.”
Construction on the project is expected to begin in 2027, with completion targeted for 2030, according to airport officials.
The Concourse D project is one of several large infrastructure upgrades underway at Miami International Airport as officials work to prepare the facility for long-term passenger growth. Since the pandemic, Miami has emerged as one of the fastest-growing international travel hubs in the United States, particularly for flights connecting North America with Latin America and the Caribbean.
The airport’s modernization program aims to improve operational efficiency while enhancing passenger comfort and accessibility across terminals.
The Concourse D expansion will also focus on sustainability and resilient infrastructure. The project is expected to pursue LEED Silver certification from the U.S. Green Building Council and Envision Verified certification from the Institute for Sustainable Infrastructure, both of which recognize environmentally responsible and durable infrastructure projects.
Airport leaders say the combination of new gates, modern systems and improved passenger areas will position Miami International Airport to handle rising travel demand while strengthening its role as a major global aviation hub.
