American Express offers some of the best airport lounge benefits of any credit card both in the USA and the UK via its Platinum Card. A complimentary membership to Priority Pass gives access to over 600 clubs worldwide, such as the Aspire lounge at London Heathrow Terminal 5, and you can also show your Platinum Card to get access to additional lounges operated by Airspace and Delta Air Lines as well as the Eurostar lounge – I have reviewed St Pancras lounge.
American Express additionally operates its own airport lounges and is expanding that network within the U.S.
The American Express Centurion Lounges include Las Vegas (Concourse D, served by United Airlines), Dallas/Fort Worth (Terminal D, served by American Airlines and international departures), New York-LaGuardia American Express Lounge with I have reviewed (Terminal B, Landside), San Francisco (Terminal 3 Concourse F, served by United Airlines), Miami (North Terminal Concourse D, served by American Airlines), and Houston (Terminal D).
The Centurion Studio is also included and is similar to the Centurion Lounge network but in a more boutique setting, is available in Seattle (Concourse B, served by Delta Air Lines, Southwest Airlines, and Virgin America).
The Centurion Lounges are complimentary for American Express Platinum Card or Centurion Card holders. They tend to be a great deal better than domestic U.S. lounges. Menus for each Centurion Lounge are designed by a different gourmet chef.
In Las Vegas chef Scott Conant (in Las Vegas, pictured above) cooks up a feast for the lounge, In La Guardia its chef Cedric Vongerichten and so fourth. This means the food and drinks are excellent individual to the location to the lounge, for example in Dallas-Fort Worth think Tacos and a Texas Toast cocktail (sparkling wine, whiskey, sherry, maple syrup mixed). Decent sitting areas are very much an upgraded offering from the equivalent lounge that can be accessed using your Priority Pass. The Centurion Lounges, with the exception of LaGuardia, also have shower suites.
All of these benefits are included in the Centurion Lounge entry fee, which is waived for Platinum and Centurion Cardholders. (Other American Express Cardholders must pay $50 per person.) including spa treatments at the Exhale Spa in Dallas/Fort Worth and Miami.
American Express also operates international lounges including Centurion Clubs in Mexico City (MEX) (T1, T1 Platinum, T2), Buenos Aires (EZE), Rio De Janeiro (SDU), and Sao Paulo (CGH) as well as the Platinum Lounges in Mumbai (BOM) and Delhi (DEL).
Centurion Lounges in the US are complimentary for those with the Platinum Charge Card or Centurion Card from American Express. Cardholders are permitted to bring two adult companions, or a spouse and two children, to the Centurion Clubs (restricted to one guest at the Centurion Studio), while access to the Platinum Lounges is limited to one companion. Additional guests may be permitted for a fee. Guests with any other American Express card may enter any of the US Centurion Lounge locations, excluding the Centurion Studio, for a $50 fee.
