American Airlines is significantly investing in its Miami hub, with plans to open a brand-new Flagship Lounge and expand its Admirals Club offering at Miami International Airport (MIA). Once completed, the developments will nearly double the lounge space available to American passengers transiting through one of its busiest international gateways.
For UK-based travellers connecting through Miami, this upgrade will likely mean a much-improved experience, especially during peak periods.

What’s Changing?
American currently operates three lounges at MIA:
- Admirals Club at Gate D15
- Admirals Club at Gate D30
- Flagship Lounge at Gate D30 (opened in 2017)
Under the expansion plans:
- The current Flagship Lounge at D30 will be repurposed into an expanded Admirals Club.
- A newly constructed Flagship Lounge will debut, offering an upgraded premium space with high-end dining and refined amenities.
Further construction timelines and opening dates are yet to be confirmed.
What to Expect: Elevated Flagship Experience
If the recently opened Philadelphia (PHL) Flagship Lounge – a sprawling 25,000-square-foot facility – is anything to go by, MIA’s upgraded offering will be a step change.
Expect:
- A champagne welcome
- Locally inspired à la carte menus
- Elegant “villas” with spa-style showers and private workspaces
- Dedicated zones for relaxation, dining, productivity and families

The design approach aims to create a hospitality-style feel rather than a conventional airport lounge – a notable shift in how American is positioning its premium ground product.
Why It Matters to UK Travellers
While Miami may not be the most common direct destination from the UK, it’s a major connecting point for British Airways and American Airlines joint venture passengers heading across the Americas and the Caribbean.
With American now serving 90 unique destinations from MIA, including recent launches such as Rome (FCO), the upgraded lounge facilities will offer a much-needed retreat for connecting passengers, especially those on long-haul itineraries.
“Miami is our international gateway,” said Juan Carlos Liscano, American’s Vice President of MIA Operations. “The lounge experience plays a key role in enhancing that travel journey.”
Bottom line
American could definitely use the extra lounge space at Miami. What happens in the meantime though and how long the project takes to complete are definite issues in the short term for regular AA flyers…
