Plain English summary

TierPath is an independent informational tool. We help you plan paths to airline elite status, but we are not Delta, American, United, Southwest, American Express, Chase, Citi, or Barclays. We are not affiliated with any of them. The numbers we show are estimates based on publicly documented program rules, those rules can change, and we may have errors. Verify before making big spending decisions.

Not affiliated

"Delta SkyMiles", "American AAdvantage", "United MileagePlus", "Southwest Rapid Rewards", "Medallion", "American Express", and any other airline, hotel, or card-issuer trademarks referenced on this site are the property of their respective owners. TierPath has no commercial, contractual, or sponsorship relationship with any of them.

Informational use only

TierPath outputs are estimates and recommendations, not financial advice. Program rules change. Promotion details change. Card terms change. Your actual results will depend on what airlines and card issuers do, not what our calculator shows. Make your own decisions. We are not liable for any spending decisions you make based on our output.

Rules verification date

Each calculation includes a "rules verified" date, indicating when we last cross-checked the program rules underlying that calculation. Newer is better. If you see a date older than 90 days, treat the result as approximate and verify against the airline's official site.

No warranty

TierPath is provided "as is" without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Use at your own risk.

Acceptable use

Do not scrape, abuse the API, or attempt to deanonymize other users (you couldn't anyway, we don't store anything that would let you do that). Do not use TierPath for any unlawful purpose.

Changes to this product

We may add features, retire features, change pricing, or shut TierPath down. We'll do our best to give notice, but we make no commitment about uptime or longevity.
