IAH: Secluded in the international terminal, this hidden gem isn't the largest in Amex's network, but it's still worth a visit. With an impressive food line-up and hand-crafted cocktails, you won't regret making the trek.

LAS: The Las Vegas Centurion Lounge was Amex's first to open over eight years ago. It just got a fresh remodel and expansion, boosting capacity by nearly 50%. There are now additional multipurpose rooms, new private telephone booths, reimagined workspace areas and a redesigned reception area, pictured above.

PHX: Amex's well-designed Phoenix outpost is sure to impress. There's plenty of space to spread out, whether you're looking to catch up on emails or watch the latest season of your favorite show. The best part? There's an auxiliary room that's opened during peak times to alleviate overcrowding.

SFO: True to its Northern California roots, this lounge has a glass wine cellar — an ode to the region’s many award-winning vineyards in nearby Napa and Sonoma counties.

Plus, with a planned expansion opening in late 2022, the lounge will soon have plenty of space for your entire party.

SEA: The food is great, and the drink selection is top-notch. Finding a seat, however, can be a challenge, especially during peak times. Fortunately, help is on the way — Amex is building a brand-new replacement that's triple the existing size.

As if that wasn't enough, you'll also find a Body Lab by Equinox and other premium amenities in Amex's flagship lounge.

LGA: Amex just opened a brand-new Centurion Lounge location in New York's LaGuardia airport. Unlike its predecessor, this lounge is located past security, in the airport's newest terminal.
