Since I don’t have an eligible credit card, AmEx offered me access to without one. A Centurion representative gave me a tour before I explored for a bit on my own.
Guests with AmEx Platinum, Business Platinum, or Centurion credit cards otherwise get complimentary access to any Centurion Lounge. Most cardholders must pay $50 per adult guest and $30 per child between ages 2 and 17. Children under 2 are free.
Cardholders who spend $75,000 on their card within a calendar year can bring up to two additional guests for free.
People with Delta SkyMiles Reserve or Reserve Business credit cards can also access Centurion lounges, but only when flying Delta, and they cannot bring free guests. Starting in February, the number of visits for the SkyMiles Reserve card is capped at 15 unless users spend at least $75,000 the previous year.
