American Airlines CEO Robert Isom said: “The brand-new, reimagined D60 is a transformational project that will provide a much-improved experience for our customers and our team.
“This investment — alongside new premium lounges and new routes — reflects our shared commitment with Miami-Dade County and the airport to ensure Miami remains the preeminent US gateway to Latin America.”
In addition to infrastructure improvements, American Airlines recently announced new lounge facilities at MIA, including a Flagship lounge and an expanded Admirals Club.
The airline has introduced self-service kiosks for quicker check-ins and implemented new technologies through partnerships with agencies like the Transportation Security Administration (TSA) and Customs and Border Protection (CBP).
These initiatives include TSA PreCheck Touchless ID and Enhanced Passenger Processing programmes aimed at expediting security screening procedures.
Miami-Dade County Mayor Daniella Levine Cava said: “The D60 expansion is one of the most monumental customer service improvements within our unprecedented airport-wide modernisation plan, which will transform the passenger experience at MIA from the cabin to the curb over the next five years.”
American Airlines’ ongoing investments at MIA form part of a wider multi-year strategy focused on updating airport facilities, enhancing operational efficiency, and supporting Miami’s role as a hub for international air travel.
