TopCashback has boosted rates across IHG, Radisson, Viator, GetYourGuide, Klook, Expedia and more, but the 'up to' qualifiers change the deal. Viator's 15% is only for new customers, while existing customers earn 10%. Expedia's 10% applies only to new customers booking activities, with existing customers seeing 5%-8% for other travel. IHG's 12% is limited to Iberostar, though all IHG brands earn 10%. No expiry is listed, so compare rates on Cashback Monitor or Savewise before committing.

Southwest Rapid Rewards members can earn 2,400 points on a qualifying Avis or Budget rental now through November 15, 2026, quadrupling the standard 600. At 1.3 cents per point, that's roughly $31 toward flights, and the flat payout means a cheap weekend rental yields the same as a weeklong one. A potential surcharge of up to $1 per day and the need to attach your Rapid Rewards number to the reservation are the only catches; bonus points won't count toward status or Companion Pass.
