Amex Experiments with “Sidecar” Lounges to Fix Centurion Overcrowding

American Express is quietly piloting a new concept in its premium airport lounge portfolio: the Centurion “Sidecar” Lounge — a secondary space designed to alleviate the infamous overcrowding issues plaguing its flagship Centurion Lounges.

With growing complaints from Platinum and Centurion cardmembers about long lines, waitlists, and packed seating, Amex is finally trying something new. But is this a real fix, or just a temporary patch?

Here’s what we know — and why it matters.

🚪 The Centurion Lounge Problem

For years, Centurion Lounges have been a gold standard in airport comfort. Think:
🍽️ Complimentary hot meals
🍸 Premium open bars
🛋️ Sleek design and modern work/rest zones

But ever since Amex expanded Platinum card access — and travelers returned in full force post-pandemic — the lounges have become overrun.

Some frequent flyers now describe Centurion Lounges as:

• “Standing-room only”

• “More packed than the gate area”

• “Luxury cattle pens”

Amex has already tried to control demand with access restrictions:

• Guests are no longer free for Platinum cardholders unless they hit a $75K spend threshold

• No access upon arrival at your home airport

• Entry limited to 3 hours before your flight

Still, the problem persists. That’s where the “Sidecar Lounge” comes in.

🧩 What Is a “Sidecar” Lounge?

The Sidecar Lounge is a new Amex concept: a small, adjacent space to an existing Centurion Lounge, built specifically to absorb overflow crowds.

It’s not a full-service lounge — more like a “Centurion Lite” — but it gives travelers somewhere comfortable to wait when the main lounge is at capacity.

Here’s what you can expect from a Sidecar Lounge:

✅ Premium seating
✅ Light refreshments (e.g., snacks and soft drinks)
✅ Access for the same eligible cardholders
❌ No full bar or plated meals
❌ No showers or spa services

Think of it as a well-appointed overflow room — quiet, clean, with just enough amenities to make your wait more pleasant without being over-the-top.

📍 First Location: Las Vegas (LAS)

American Express is testing the first Sidecar Lounge at Harry Reid International Airport (LAS) in Las Vegas, where the existing Centurion Lounge often hits capacity.

LAS is a smart testbed:

• High leisure traffic

• Busy at all times of day

• Frequent Amex Platinum and Delta Reserve travelers

If the experiment proves successful, Amex may expand the concept to other overcrowded Centurion locations like:

• Dallas-Fort Worth (DFW)

• Miami (MIA)

• New York (JFK)

• Denver (DEN)

• San Francisco (SFO)

Amex has not officially confirmed future Sidecar locations yet, but the logic points toward other hubs facing frequent waitlist scenarios.

💡 Why This Matters

At $695/year, the Amex Platinum Card is a premium product. Lounge access is a huge part of that value proposition — and the current experience doesn’t always meet expectations.

The Sidecar Lounge is Amex’s way of balancing value with demand. By giving overflow guests a dedicated space, they can:

• Maintain the exclusivity of the main lounge

• Offer a backup option without degrading service

• Avoid further tightening access rules (for now)

For cardholders, this could mean fewer denied entries, shorter waits, and more consistent comfort — even if it’s not quite the full Centurion experience.

🧠 Final Thoughts: Step Forward or a Band-Aid?

The Centurion Sidecar Lounge concept is a creative, potentially game-changing solution — but it’s not without caveats.

It doesn’t fix the root problem (too many Platinum cardholders, not enough lounge space). And the scaled-back amenities may feel underwhelming to some.

Still, it’s a welcome experiment. Compared to other solutions — like further restricting access or degrading lounge quality — the Sidecar Lounge could be a smart compromise.

With competition heating up from Capital One Lounges and Chase Sapphire Lounges, Amex is under pressure to innovate. And in a world where space is luxury, offering more of it might just be the edge they need.
