Amex Expands Lounge Network In Boston, Charlotte And DFW — But Boston Won’t Open Until 2029

American Express has announced a forthcoming Boston Centurion lounge, Charlotte Sidecar, and a 50% expansion of the Centurion lounge at Dallas – Fort Worth airport. All great news for American Express Platinum Card® cardmembers.

Boston Won’t Be Ready Until 2029

American Express announced their signed lease on a new Centurion Lounge at the Boston airport in terminal C. It will be two stories, with an outdoor terrace, and offer standard amenities (workstations, power, food and beverage). The lounge isn’t expected to open until 2029.

Fourteen months ago the airport authority approved the project and it was projected to be completed in 2027, so 2029 is an unfortunate miss. Back in September I wrote that Massport said the project had slipped to 2028. I’ll leave to y’all in the comments to discuss Massport construction competence and cost, since it’s Massport building the core and shell.

I reported at the time that the space is approximately 20,000 square feet near gate C10.

Sidecar Coming Next Year To Charlotte

Sidecar is American Express’s sit down dining concept, with small spaces that are in addition to Centurion lounges at an airport. They just opened their first one in Las Vegas and announced a second for Charlotte.

On March 7 I wrote based on airport documents that American Express would open its second Sidecar location in Charlotte. American Express is now officially announcing this.

At 4,641 square feet it’s a larger space than their Las Vegas outpost, and it will be located on the airport’s Concourse A Expansion Phase 2 project (so unlike Las Vegas, not close to the Centurion lounge at D/E). It’s a 5-year lease with 5 year option at $200 per square foot with 2.5% annual escalator and a minimum $7.15 million capital investment in the space.

The concept involves ordering small plates and drinks via QR code to be delivered to your seat. And this one will include a Blue Roast by American Express Coffee (like you find in New York JFK, Salt Lake City and Seattle, which is great) and have restrooms, power, and wifi.

As in Las Vegas, access for Platinum cardmembers isn’t until 90 minutes prior to scheduled flight departure, which means often spending about 40 minutes in the space if you can get in right at the first moment (give walks to the gate for the start of boarding to ensure overhead bin space).

American Express says that it’ll open in 2027.

Expanding DFW Centurion By 50%

Dallas was the second Centurion lounge after Las Vegas. It’s already in its second location in the D terminal at DFW (gate D12), and I did not realize there was additional adjacent space to extend into.

American Express announced a deal to expand and renovate the existing club, gaining ~ 50% more space. They’re adding seats, a new dining area and a second bar. They’ll also have a “walk-up ice
cream window.” (The lounge has pretty regularly had ice cream since March 2024.) The expanded space is expected to open next year.

By way of background, DFW’s board approved an amended lease on August 7, 2025. That extends the lease to September 26, 2040 and increases the size of the space from 12,000 to 18,619 square feet, an increase of 6,619 square feet or about 55%. American Express is touting a slightly smaller increase because the lounge was previously described as 12,500 square feet.

This excludes lounges like Plaza Premium and Priority Pass network lounges that Platinum cards have access to, but that aren’t American Express-branded. While I don’t love the food, and I think broadly that the design aesthetic is stale, American Express simply has a lot more lounges than competitors do. And their coffee bars have been strong adds, even if not genuinely unique (Cf. Alaska, United Club Fly).

Centurion U.S. Lounge Access Rules

Platinum cardmembers get acceess for themselves with their Platinum Card, a same-day boarding pass, and government ID, generally within 3 hours of your departing flight.

Starting July 8, 2026, connecting passengers are limited to entering within 5 hours of their departing flight from their connecting city, and same-day roundtrips are not counted as connecting flights (so the entry rule is 3 hours prior to departure, rather than 5 hours).

Guests are no longer free with the card without spending $75,000 in eligible purchases in a calendar year on the card account. That unlocks 2 complimentary guests per visit. Otherwise it’s $50 per guest or $30 for children ages 2–17.
