Guest rules

Many premium cards still offer guest privileges, but several major issuers have recently moved to a pay-per-guest model or added same-flight requirements. The exact policy depends on whether you're entering a Priority Pass lounge, an Amex Centurion lounge, an airline alliance lounge, or a Plaza Premium / Plaza-network lounge — and whether your match is on the same flight. Lounge Surf checks the current policy automatically when matching you with another traveler.

Amex Platinum in 2026 — networks, guest rules, what's changing

The American Express Platinum Card remains a powerhouse of premium travel. As of 2026, it opens 1,550+ lounges across 700+ airports globally through a stack of overlapping programs.

Where Amex Platinum opens doors in 2026

• The Centurion Network: 30+ proprietary lounges, including the new small-format "Sidecar" locations rolling out in 2026.
• Priority Pass Select: access to 1,400+ independent lounges (enrollment required).
• Lufthansa Group (🚨 ending September 30, 2026): Lufthansa Business, Senator, plus Eurowings and Discover Airlines lounges — until that date.
• Delta Sky Club: access only when flying Delta, capped at 10 visits per year unless the cardholder hits US$75k+ in annual spend.
• Plaza Premium & Escape Lounges: full access across both global networks.

Guest rules in 2026

Two milestones to keep separate:

• In effect since February 2023: US Personal and Business Platinum cardholders are limited to 1 complimentary guest in Centurion Lounges. Additional guests cost about US$50 each, unless the cardholder hits US$75k+ in annual spend.
• New for July 8, 2026: guests must be on the same flight as the cardholder, and Centurion entry is capped at 5 hours before the connecting flight. Boarding-pass checks at the desk are strict.
• Priority Pass: still allows 1 free guest via the Amex-issued membership.

🚨 Lufthansa Group access ends September 30, 2026

After that date, Amex Platinum no longer opens Lufthansa Business, Senator, Eurowings, or Discover Airlines lounges. Travelers based in Germany, Switzerland, and Austria are most affected — particularly through FRA, MUC, and ZRH. The fallback: Priority Pass alternatives at the same airport (like Frankfurt's LuxxLounge), or matching via Lounge Surf with a Star Alliance Gold member who can host you under alliance rules.

How Lounge Surf helps with the "same flight" rule

Now that Centurion access requires guest and host to be on the same flight, Lounge Surf's matching is more useful than ever — the algorithm filters travelers on your specific flight or alliance, so the lounge agent at the desk accepts the guest without question. The match never violates the new policy because the policy is the input to the match.
