Airline shopping portal bonus tiers by program
Each program is reported to use three spend tiers, and the amounts differ widely. Southwest is the most generous at the top tier, while Alaska's tiers are the smallest. The table below compares the reported thresholds and bonus miles so you can see where your planned purchase would land.
| Program | Lowest tier | Middle tier | Top tier | Reported end date |
|---|---|---|---|---|
| Southwest Rapid Rewards | 500 miles at $100 | 2,000 miles at $400 | 5,000 miles at $800 | Nov. 23 |
| United MileagePlus | 500 miles at $125 | 2,000 miles at $500 | 4,000 miles at $1,600 | Nov. 20 |
| American AAdvantage | 500 miles at $200 | 1,500 miles at $600 | 2,500 miles at $1,200 | Nov. 20 |
| Alaska Atmos Rewards | 300 miles at $100 | 750 miles at $350 | 1,500 miles at $650 | Nov. 20 |

Are airline shopping portal bonuses worth using
These bonuses can be a low-effort way to earn miles without flying or holding an airline credit card, but they only matter if you were already planning the purchase. Spending more to reach a higher tier rarely makes sense, because the bonus is small compared with the extra money spent. The best case is a purchase you would make anyway that happens to sit just below or above a tier threshold.
Look at the ratio rather than the headline number. Southwest's top tier pays 5,000 miles on $800, while American's top tier pays 2,500 miles on $1,200, so the same spend earns noticeably different bonuses depending on the program you collect. If you have a choice of which airline to credit, compare tiers before you click through.
How to claim an airline shopping portal bonus before it ends
Start from the airline's own shopping portal rather than the retailer's site, and confirm the offer terms on the portal before you check out. Buy before the end date that applies to your program: Nov. 20 for United, American and Alaska, Nov. 21 for Delta and Nov. 23 for Southwest. Keep the order confirmation, since portal credit can take time to post and may need follow-up if it does not appear.
