Which current bonus offers are worth chasing?

The 30% Amex Membership Rewards to Avios transfer bonus (through September 27) is the most straightforward winner in this batch. Avios are usable across British Airways, Iberia, Aer Lingus, Finnair, and Qatar Airways, and you can move them freely between those programs. If you have a specific award redemption in mind—especially for short-haul flights or business-class redemptions on partners—this bonus effectively gives you 30% more buying power. No registration required, just transfer before the deadline.

The World of Hyatt Latin America resort promotion is interesting but requires patience. You must register by September 30, then stay between January 1 and March 31, 2027, to earn one category 1–4 free night award for every three paid nights, up to five awards. The free nights expire June 30, 2027. If you already have a sun-soaked winter escape planned at one of the listed resorts, this is free value. If you don't, planning a trip just for the promotion probably doesn't make sense—the free nights are only useful if you can use them before they vanish.

The Marriott points sale (through September 9) offers a 50% bonus and an increased purchase limit of 200,000 points. At roughly 0.83 cents per point, this is the lowest price Marriott has offered in recent years. It can be a good deal if you have a specific high-value redemption in mind, especially at properties where the fifth-night-free benefit applies. But Marriott uses dynamic award pricing, so you must check actual cash versus points cost before buying. The Southwest Companion Pass offer (register by August 6, travel by November 18) is a narrow two-month window—useful only if your fall travel plans are already set.

The Qatar Airways monthly award flight offer (book by August 14 for travel through September 30) promises up to 25% off Avios awards on select routes. Without a public landing page showing which routes are discounted, this is hard to evaluate. If you already see a specific Qatar award you want, check if it qualifies. Otherwise, don't go hunting for a deal that might not apply to your trip.
