Centurion Lounge

Terminal D flyers with Amex Platinum usually skip the KLM/AF lounges and head here instead.

The Centurion Lounge sits in Terminal D at IAH and follows the standard Amex Platinum/Centurion entry rules, including guest access tied to the cardholder. If your KLM or Air France lounge option in D has only basic buffet trays out, regulars say the food and drink spread here comes out ahead more often than not.

Hours track typical long-haul banks in Terminal D, so it opens in time for mid-morning departures and runs into the late-evening departure waves; check the Amex app day-of because times shift with schedules. Access is post-security in Terminal D, and staying within A–E at IAH means you can use the Skyway airside train to reach D without re-clearing security, which can easily save you 20–30 minutes.

Entry requires an American Express Platinum or Centurion card physically present, plus a same-day boarding pass; guesting follows the current Amex policy, so don’t assume you can walk in three friends if the rule that day says two. FlyerTalk reports confirm that Terminal D staff enforce those guest numbers closely, especially during the late-afternoon Europe bank between about 14:00 and 18:00.

The room gets compared to a bomb shelter in reviews, which tracks with how enclosed it feels compared with glass-walled spaces in Terminals C and E. You’re not here for runway views; you’re here for a controlled environment away from the D-gate seating crush that builds around the 16:00–20:00 long-haul push.

Food quality scores higher than the KLM/AF options when those airline lounges lean on cold snacks and limited hot trays, but you’re still looking at buffet-style service rather than made-to-order meals. Drinks include a proper bar setup with standard spirits and cocktails included, which stacks up well against pay-per-drink bars near gates D6–D10.

What regulars do: they check KLM or AF lounge photos in real time, then walk to the Centurion in Terminal D if the airline offerings look thin. They also confirm their Amex card, digital card access, and exact guest allowance before leaving gates C or E so they don’t waste a 10–15 minute Skyway ride only to get turned away.

Practical tip: build a 45-minute buffer before boarding at D if you’re coming from Terminal B or C via the Skyway and want at least 20 solid minutes inside the Centurion Lounge, especially before evening Europe departures.
