Amex ends the Etihad Guest partnership worldwide, closes Mumbai's Centurion Lounge, and cuts guests to one

Three separate Amex changes landed inside three weeks, in three different parts of the product. Taken one at a time each looks like housekeeping. Taken together they describe a card that is being made cheaper to run.

One: Etihad Guest is gone, everywhere

Etihad Guest stopped being a Membership Rewards transfer partner on a rolling market-by-market schedule:

The Indian removal took effect 1 July 2026. Neither company has publicly given a reason. The staggered dates across four continents are what make this a partnership ending rather than a regional pricing decision.

Etihad itself has not gone anywhere: it remains reachable from Capital One miles, Citi ThankYou points and Bilt, among others. What ended is the Amex route to it. If Membership Rewards was your only path to Gulf-carrier premium cabins, you no longer have one.

Two: Mumbai's Centurion Lounge closed

Amex permanently closed the Centurion Lounge at Mumbai Airport Terminal 2 on 1 July 2026. Platinum Card Members are directed instead to the Adani Business Class Lounge in domestic departures.

A shared airport lounge is not a Centurion Lounge, and Amex's India pitch leaned on that distinction for years. The Mumbai closure removes the one physical asset that made the proposition tangible in the country's busiest airport.

Three: one guest, same flight, five-hour window

From 8 July 2026, Centurion Lounge entry rules tightened on two axes at once:

• Complimentary guest access drops from two guests to one for eligible Platinum Personal and Platinum Business Card Members.
• Every guest must be travelling on the same flight as the Card Member. A partner on a separate booking that day no longer gets in.
• Members on a connecting itinerary are admitted only within five hours of departure, where previously connections carried no time limit.

The rules apply at Centurion Lounges in the United States and at London Heathrow, Tokyo Haneda and Hong Kong. Centurion Card holders are not affected.

What it adds up to

Amex is pricing lounge congestion and partner acquisition at the same time, and both bills are being paid by the cardholder rather than the issuer. The guest cut is the most quietly expensive of the three: for a couple who travelled together on separate bookings, a benefit that covered two people now covers one, without the fee moving a rupee or a dollar.

The transfer-partner removal carries the more durable lesson. A transfer partner is a commercial agreement, not a feature of your balance, and it can be withdrawn in three weeks across every market at once. Points held for a redemption two years out are exposed to that on every one of those days.

What to do

If you hold Membership Rewards and were saving for a Gulf-carrier redemption, re-price the trip against the partners Amex still has rather than waiting for Etihad to come back. If you valued the card mainly for lounge guesting, work out what the second guest was worth to you per year and subtract it from the card's value honestly before you renew.

The transfer partner matrix shows which programs each card can still reach, and Polo Match ranks cards on net annual value once a benefit like this comes off the table.
