September 2026 is stacking up as a good month for anyone who plays the points game. The latest round-up from The Points Guy pulls together the airline, hotel, rental car and credit card promotions worth registering for before the deadlines slip by — and a few stand out.

Cathay Pacific is marking its 80th anniversary with real money off flights to Asia. Promo code CX80HKUS takes $80 per ticket to Hong Kong, while CX80US knocks $88 off tickets to Asia and beyond, across economy, premium economy and business class. Quantities are limited and first come, first served, with the offer closing on Sept. 23. New Cathay members can also grab up to 1,946 bonus miles on a first flight from the U.S. or Canada if they register and book by Sept. 15.

Qatar Airways Privilege Club is running its own bonus push through Sept. 18: 20% off plus up to 14,000 bonus Avios on eligible flights from the U.K. or Europe, stacked from three separate bonuses (10,000 for booking with code SEPTPC26, plus 2,000 each for a first online booking and new membership). Bookings also come with one free date change. Travel needs to wrap up by Dec. 10, 2026 one-way, or May 31, 2027 for round trips.

On the hotel side, World of Hyatt is doubling base points at Thompson properties for stays booked through the Hyatt app and completed by Nov. 10 — repeatable up to a 30,000-point cap, which TPG values at $495. Marriott has two deals: 20,000 bonus points on Hawaii or Mexico vacation packages of three-plus nights booked by Sept. 30 for travel through March 2027, and up to 4,500 bonus points per qualifying stay between Sept. 22 and Nov. 22 if registered by Nov. 13.

Hertz is giving a free fifth day on SUV or minivan rentals of four to 27 days in the U.S. with promo code 212109, for pickups by Dec. 31 — easy to stack with elite status perks from your credit card.

Credit card users should check their Amex offers, where targeted deals include $200 back on a $450-plus Marriott spend across North America and the Caribbean, $200 off a Holland America cruise booking of $750 or more (by Oct. 22), and $50 back on a $250 prepaid Europcar rental booked by Oct. 21. Meanwhile, Flying Blue's September Promo Rewards cut award flights to and from Europe by up to 25% if booked by Sept. 30.

Longer-running offers are still live too: 50,000 bonus points plus breakfast for two at the Ritz-Carlton Kyoto through Sept. 30, 2,000 bonus Bonvoy points per night at 60 properties across Thailand, a Hyatt free-night-per-three-stays promo across Latin America and the Caribbean for winter stays, and double points at more than 4,000 Best Western hotels worldwide through the end of the year.

If you have trips pencilled in for autumn or winter, most of these require registering before you book — so it's worth 15 minutes now to check which ones apply to your accounts.
