Designs for a $1 billion expanded Concourse D at Miami International Airport (MIA) have been unveiled by American Airlines and Miami-Dade County.
Currently equipped to support smaller regional jets, the revamped three-level concourse will feature a new section, Gate D60, and create 17 additional gates designed for larger aircraft and eliminate outside boarding.
Passengers will also wait for their flights in individual boarding areas rather than shared waiting spaces.
The new concourse, said American Airlines, will also feature “bright, expansive spaces with sprawling indoor palm trees, as well as new dining and shopping options for travelers.”
What’s more, the expansion aims to make international travel more seamless with direct third-floor access to the customs hall.
The project is due to break ground in 2027, and is being hailed by Miami-Dade County Mayor Daniella Levine Cava as a “monumental customer service improvement.”
She added: “The D60 expansion… will transform the passenger experience at MIA from the cabin to the curb over the next five years.”
MIA served approximately 55.3 million passengers in 2025, with around 20 million of those flying with American and regional brand American Eagle.
American’s VP of MIA Operations, Juan Carlos Liscano, said: “American and Miami-Dade have built a partnership across decades that intertwines our success and vitality.
“We share a vision and legacy that has elevated Miami into the leading global gateway it is today — and positions us for exciting growth ahead.
“Our continued momentum is powered by 15,500 MIA-based team members who reflect the vibrancy of the communities we serve and embody our pride in being Miami’s hometown airline.”
