Miami-Dade County Mayor Daniella Levine Cava and American Airlines CEO Robert Isom have unveiled plans to expand Miami International Airport’s Concourse D with a “monumental” new $1 billion investment. The new Gate D60 expansion will create 17 new aircraft gates and adjoining passenger boarding areas, additional dining and shopping options, boost baggage handling and streamline customs access.
Scheduled to break ground in 2027 and be completed by 2030, three-level extension will convert the existing gate D60 area – which currently has one common boarding space and 17 ground-level gates for smaller regional jets – into 17 traditional contact gates for larger regional and narrow-body aircraft, each with individual, spacious passenger hold rooms. All 17 gate areas will provide convenient third-level connections to Concourse D’s U.S. Customs and Border Protection facility 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,” commented Miami-Dade County Mayor Daniella Levine Cava during the presentation on February 25.
“MIA ranks among the fastest-growing global hubs since the pandemic, and the North Terminal expansion, coupled with South Terminal’s future Concourse K and the Central Terminal redevelopment, will create a new future-ready gateway fully enabled to serve our millions of visitors for decades to come,” she added.
The new Gate D60 extension also includes several sustainable building features designed to earn the facility LEED (Leadership in Energy and Environmental Design) Silver and Envision Verified certifications – the highest ratings for resilient structures by the U.S. Green Building Council and theInstitute for Sustainable Infrastructure.
“Miami is an important hub and gateway for American, and it’s an essential part of our history and our future. The brand new, reimagined D60 is a transformational project that will provide a much-improved experience for our customers and our team,” added American Airline’s CEO Robert Isom. “This investment — alongside new premium lounges and new routes — reflects our shared commitment with Miami-Dade County and the airport to deliver a consistent, elevated customer experience.”
The Gate D60 expansion is one of more than 200 projects within the Miami’s sweeping $9 billion M.I.A. Plan. Other major projects include a new garage that opened in December; the new Concourse K expansion scheduled to open in 2029; and the $745-million Central Terminal redevelopment project, which will modernize MIA’s oldest terminal area by 2031, plus major renovation and maintenance projects.
Miami International Airport, America’s busiest airport for international freight and the second busiest for international passengers, recording more than 55 million domestic and international passengers in 2025.
