American Express Centurion Lounge

Terminal B’s Centurion Lounge mostly catches Amex cardholders on domestic hops

This American Express Centurion Lounge sits airside in Terminal B at Monterrey International Airport (MTY), mainly used by Amex cardholders flying domestic routes on Aeroméxico and Volaris. Think of it as a step up from waiting at gates B1–B12, not a flagship club. Access follows standard Amex rules: Centurion and Platinum cardmembers with same-day boarding passes in Terminal B get in, guests may depend on your specific card and country rules.

Terminal B at MTY handles a solid mix of domestic traffic, so the lounge tends to see early morning and late afternoon business banks tied to Aeroméxico departures. If you’re connecting from Terminal A or C, factor in the terminal transfer and security; MTY’s three-terminal layout eats time, and you need to clear security in B before heading to the Centurion door on the concourse level.

Food expectations should sit closer to “light meal before a 90-minute hop” than a multi-course spread. Reviews on this specific MTY Centurion-branded lounge are rare, but Amex’s regional pattern in Mexico usually means a small buffet with hot items at meal times and snacks in between. Drinks typically include basic spirits, beer, and wine at no extra charge, with premium labels sometimes available for a fee in other Mexican locations, so carry a backup plan if you care about a particular brand.

Seating in Terminal B is limited in the public area near gates, so the lounge mainly wins on having extra chairs, some tables to work on, and access to power outlets for laptops and phones. Wi‑Fi is usually faster than the free terminal network in comparable Amex lounges in Mexico, so this is a decent spot to clear email ahead of a 1–2 hour domestic leg. Don’t expect shower suites or nap rooms like you’d find in larger Centurion hubs.

With almost no first-hand reports on Flyertalk or Reddit, treat this MTY Terminal B Centurion Lounge as a practical backup, not the centerpiece of your trip. One simple move: check how far your gate is from the lounge on the B concourse map before heading in, and set a 20-minute timer so you’re not sprinting when boarding for your Aeroméxico or Volaris flight starts.
