American Express has quietly rebranded and expanded one of its most underrated Platinum Card perks. The old International Airline Program (IAP) is now called Platinum Member Airfares , and the upgrade is substantial. More airlines, broader cabin eligibility, and a first for the program: domestic economy fares are now included.
What Changed: IAP Becomes Platinum Member Airfares
American Express launched Platinum Member Airfares in mid-April 2026, replacing the International Airline Program that had existed for years. The core benefit , discounted airfares exclusively for Amex Platinum cardholders , remains, but the scope has grown considerably.
Here’s what’s new under the expanded program:
- More airlines: Roughly 30 airlines now participate, up from the previous selection.
- Domestic economy included: For the first time, the program now covers domestic economy fares, not just international premium cabins.
- Up to 7 companions: Cardholders can book discounted fares for themselves plus up to 7 traveling companions on the same itinerary.
- Savings of approximately 10% on participating premium international cabin fares.
- Still earns 5x Membership Rewards: Flights booked through the program still earn 5x MR points when paid with your Amex Platinum card (on up to $500,000 in purchases per calendar year).
How Platinum Member Airfares Works
Booking is done exclusively through AmexTravel.com or by calling the Platinum Card travel line. You won’t find these fares on third-party OTAs or even the airlines’ own websites , the discounts are negotiated specifically for Platinum cardholders.
For premium international cabins (business and first class on participating carriers), the discount is approximately 10% off the published fare. On domestic economy, the discount structure varies by airline and route.
One important detail: you need to pay with your Amex Platinum card to access the discounted pricing and earn the 5x MR bonus. Using a different payment method disqualifies you from both benefits.
The 5x Earning Stack Still Applies
This is worth emphasizing. Booking through Platinum Member Airfares gives you:
- ~10% discount off the paid fare
- 5x Membership Rewards on the full ticket price
- The airline’s own frequent flyer miles on the base fare
At a conservative 1.5 cents per MR point, 5x MR on a $3,000 business class ticket equals roughly $225 in point value , on top of the ~$300 in upfront savings. The combined value frequently exceeds 15–20% off the published fare when you factor in the points.
Which Airlines Participate?
American Express has not published a fixed public list of all 30+ participating airlines. The selection has historically included major international carriers across all regions. When searching on AmexTravel.com, eligible Platinum Member Airfares fares will be tagged and displayed automatically when you’re logged in with a qualifying card.
As with the old International Airline Program, availability depends on the airline, the route, and the cabin class. Not every fare on every route will show a Platinum Member Airfares discount , it applies when the airline has made inventory available under the program.
Is It Worth Using?
Platinum Member Airfares makes the most sense for cardholders who:
- Book premium international travel: Business or first class where a 10% discount is meaningful on a $2,000–$8,000 ticket
- Are already booking through AmexTravel.com for the 5x MR earning (which the Platinum card already provides on flights booked directly with airlines or via Amex Travel)
- Travel with companions: The ability to extend the discount to 7 additional travelers on the same booking is a genuine differentiator
For domestic economy, the value is more situational. A 5–8% discount on a $400 domestic ticket saves $20–$32, which is meaningful but not transformative. The real story here is access to premium international savings.
How This Fits the Platinum Card’s Value Proposition
The Amex Platinum carries a $895 annual fee. When you start stacking the credits: $200 airline fee credit, up to $200 hotel credit (Fine Hotels + Resorts / Hotel Collection), $240 digital entertainment credit, $155 Walmart+ credit, $300 Equinox credit, and now a more expansive Member Airfares program , the effective cost of holding the card drops substantially for cardholders who travel frequently.
Platinum Member Airfares isn’t a redemption tool; you’re paying cash for these tickets. But for cardholders already booking premium international travel, the combination of the upfront discount and the 5x MR earning makes AmexTravel.com the clear first stop before checking anywhere else.

Bottom Line
Amex Platinum Member Airfares is a meaningful upgrade over the old International Airline Program. More airlines, domestic economy coverage, and companion fare access make this one of the more underutilized perks on the card. If you hold the Platinum and book premium international flights, check AmexTravel.com before you buy anywhere else.
