Miami Terminal K

Miami International Airport (MIA) announced today that it’s planning the construction of a new concourse. Concourse K will cost around $600.6 million and provide six new gates, a ground support equipment maintenance facility, enhanced baggage handling systems, and critical upgrades to airfield infrastructure. The new concourse is expected to open in 2029.

I recently wrote about how Miami International Airport (MIA) was voted best for layovers. Global Traveler announced on May 1st that Miami International Airport (MIA) won its Best Airport for Layovers Award during the 13th annual Leisure Lifestyle Awards. I was quite surprised by this as I have never found Miami to be a place where I enjoy spending time. It’s the busiest airport in the United States for international freight and the second busiest for international passengers, but I’ve always found it to be a bit depressing. Maybe my opinion will change with the significant investment being made in the airport.

The Miami-Dade County Board of County Commissioners approved the construction of the New Concourse K this week. This is one piece of the transformative infrastructure project that is happening at the airport at a cost of $9 billion. The Modernization in Action plan when complete will position the airport to accommodate 77 million passengers and five million tons of cargo by 2040.

The Concourse K addition includes:

  • Six new contact gates
  • Construction of an associated aircraft apron and jet fuel hydrant system
  • A ground support equipment maintenance facility
  • Installation of two new baggage carousels
  • Upgrades to the existing baggage handling system to connect the Central and South Terminals
  • Envision LEED Silver certification for sustainable infrastructure

Miami-Dade County Mayor, Daniella Levine Cava, said:

MIA has not seen a terminal expansion since 2007, making this a truly transformative milestone for our airport.  The launch of Concourse K will not only increase capacity and create thousands of new jobs but also reinforce MIA’s role as a premier Global Gateway. With the unwavering support of the Board of County Commissioners and the dedication of Director Ralph Cutie, his team, and our airport partners, we are making visionary, future-ready investments that will build a stronger, more vibrant airport—one that uplifts our community, welcomes the world, and powers our economy into the future.”

There is no word on what airline will take these new gates. The closest concourse (Concourse J) is home to many international airlines like Air Canada, Avianca, COPA, El Al, Emirates, and more. The gates in Concourse K will only accommodate narrow-body aircraft, which means that we’ll likely see domestic flights depart from here. It’s also slated to replace Concourse G (that was built in 1957) where Southwest, United, and others fly to/from. We’ll have to see what happens with these gates.

Anthony’s Take: Miami International Airport (MIA) will soon have a new concourse. This is the first addition since 2007 and much needed based on the passenger numbers that the airport has been hosting.

Good stuff. Maybe there will be room to add another lounge.

MIA takes a lot of “heat” (pun intended), but I like it as a connecting airport. Good lounge options, good bars/restaurants, and it’s generally a more chill experience regarding crowding vs places like ATL and CLT. The Centurion lounge there has some of the best runway views of any lounge out there, and MIA is one of the best airports for plane spotting.

Only things I have against it are not all terminals are connected behind TSA, at any given time roughly 50% of all moving sidewalks/escalators are out of commission, and when the concourse D people mover is broken you can be faced with up to a mile long hike to get to your connecting gate.
