The personal Amex Platinum Card and The Business Platinum Card are among the most powerful travel cards largely because of their airport lounge access. Both cards give eligible cardmembers entry to the American Express Global Lounge Collection — a network that includes Amex Centurion Lounges plus partner lounges worldwide. Below is a concise guide to the lounges, access rules and guest policies you should know.
Which lounge networks are included
– Amex Centurion Lounges — Amex’s own premium lounges with food, bar service, Wi‑Fi and flexible seating. Some locations offer family rooms and other amenities.
– Delta Sky Club — access when flying on the same‑day Delta‑operated flight (or Delta‑marketed flight operated by WestJet); basic economy tickets are excluded.
– Priority Pass Select — complimentary membership (enrollment required) that opens access to many independent lounges around the world (restaurant credits are generally excluded).
– Escape Lounges (Centurion Studio Partner) — available in the U.S., U.K. and Australia.
– Plaza Premium lounges — select locations worldwide (some also appear on Priority Pass lists).
– Select partner networks (Aspire, other Global Lounge Collection partners) and, until Oct. 1, 2026, select Lufthansa lounges.
General entry requirements
For nearly every lounge you must present:
– Your eligible Amex Platinum or Business Platinum card
– Government‑issued ID
– A confirmed same‑day boarding pass with a matching name
Enrollment is required for Priority Pass Select. Note that access rules, entry windows and guest policies can vary by country and by individual lounge.
Centurion Lounge highlights and rules
– Quantity and locations: There are multiple Centurion Lounges across the U.S. (about 16) and international Centurion locations in major airports. Amex continues to expand the network.
– Access window: Cardmembers may enter up to three hours before their scheduled departure for outbound flights. For connecting international itineraries, entry may be allowed up to five hours before the next departing flight. Arrival‑only access is generally not permitted unless you have a same‑day connection.
– What you get: staffed bar, complimentary meals and nonalcoholic drinks, Wi‑Fi and comfortable seating; some lounges have family rooms or special dining concepts (e.g., Sidecar).
– Guest policy (U.S.): $50 per guest (age 18+) and $30 per guest (ages 2–17); children under 2 are usually free with proof of age. Cardmembers can earn complimentary guest access for up to two guests per visit by spending $75,000 in eligible purchases on the card in a calendar year; that benefit lasts through the remainder of that calendar year, the following calendar year, and until Jan. 31 of the next year.
– International guest policies and access windows can differ, so check the specific lounge rules before travel.
Delta Sky Club rules
– Eligibility: Amex Platinum and Business Platinum cardmembers can access Delta Sky Clubs when flying on a same‑day Delta‑operated flight (or eligible Delta‑marketed flight). Basic economy fares are excluded.
– Visit limits: Cardmembers receive up to 10 Sky Club visits per program year (program year runs Feb. 1–Jan. 31). Authorized users with an additional Platinum card receive their own 10‑visit allotment.
– After the limit: Additional entries cost $50 per visit ($25 for Sky Club “Grab and Go” locations). A single visit can cover multiple Sky Clubs within 24 hours if entries occur within that 24‑hour window.
– Spending benefit: If you charge $75,000 or more in eligible purchases on your Platinum or Business Platinum card in a calendar year, you unlock unlimited Delta Sky Club access through the remainder of that program year and the next program year (subject to Delta’s terms).
– Guest policy: No complimentary guests included; guests may be purchased per Delta’s guest pricing (typically $50 or $25 for Grab and Go locations), and there are limits on how many companions you can buy access for.
Priority Pass Select
– Enrollment required: Sign up for Priority Pass Select via Amex to receive a Priority Pass membership card.
– Access: Use the Priority Pass card, ID and same‑day boarding pass to enter participating lounges (some lounges restrict Priority Pass guest hours).
– Guest policy: Many Priority Pass lounges include two complimentary guests; additional guests are charged the lounge’s guest fee. Priority Pass membership from Amex typically does not include restaurant credit offers.
Escape Lounges (Centurion Studio Partner)
– Entry: Present your eligible Amex card, ID and matching same‑day boarding pass. The eligible flight must be booked on a U.S.‑issued Amex card for U.S Escape Lounges.
– Guests: Two guests may join complimentary; additional guests can buy a day pass.
Plaza Premium and other partners
– Plaza Premium: A selection of Plaza Premium lounges worldwide admit Platinum cardmembers and up to two guests free; other guests may pay a location‑specific fee.
– Other Global Lounge Collection partners: Access rules (hours, guest allowances, fees) vary by partner and location. Always verify the specific lounge’s policy on Amex’s lounge finder.
Lufthansa lounges (note)
– Amex access to certain Lufthansa lounges is being discontinued effective Oct. 1, 2026. Until then, select Lufthansa Business and some Senator lounges admit eligible Platinum cardmembers when flying on a same‑day Lufthansa Group flight; guest rules differ by location.
Authorized users and card variants
– Authorized users who receive an additional Platinum card (not the reduced companion style) generally get their own access privileges for most networks, including the Delta Sky Club visit allotment and Priority Pass enrollment. Policies differ for companion cards and depend on the issuer’s enrollment rules.
Practical tips
– Always carry your physical (or digital, if accepted) eligible Amex card, government ID and a same‑day boarding pass.
– Enroll in Priority Pass Select before traveling to avoid surprises.
– Use Amex’s Global Lounge Collection search tool or the issuer’s lounge finder to confirm hours, exact entry requirements and temporary closures.
– If a lounge looks busy, Centurion lounges in the U.S. provide an app/QR check‑in and a waitlist system; checking in when you are close to the lounge helps.
Bottom line
Amex Platinum and Business Platinum offer the broadest lounge access among premium cards, covering Centurion Lounges plus Delta Sky Clubs, Priority Pass Select, Escape Lounges, Plaza Premium locations and other partners. That reach gives cardmembers lots of options, but each network has its own entry window, guest rules and enrollment steps. Before you travel, confirm the specific lounge’s rules and, when needed, enroll (Priority Pass) so you can make the most of the benefit.
