Air France-KLM Cuts Transatlantic Prices by Up to 25% This September
For those bargain hunters planning to traverse the Atlantic this fall, a golden opportunity awaits. Air France-KLM’s Flying Blue loyalty program has introduced its September Promo Rewards, providing discounts of up to 25% on award flights between major U.S. cities and European destinations.
The promotion encompasses departures from significant American hubs such as New York, Chicago, and San Francisco. Award redemption rates commence from as low as 18,750 miles one-way in economy class, 30,000 miles in premium economy, and 45,000 miles in business class — all in addition to the applicable taxes and fees.
Travelers are required to book by September 30, 2026, with travel availability extending through February 2027. This presents an ideal timeframe to plan a late-autumn or winter European escape at a reduced points expense. The Flying Blue Promo Rewards program, updated monthly, is frequently ranked as one of the most competitive transatlantic loyalty redemption offers for U.S.-based travelers.
Travel connoisseurs at The Points Guy underscore this as one of the standout deals of the month for vacationers adept at using miles, alongside hotel bonus promotions from Marriott Bonvoy and Hyatt. With the high demand for European autumn travel and off-peak pricing being implemented across numerous destinations, this promotion is impeccably timed for both leisure and business travelers.
