Sources
Every factual claim on this site traces back to something on this page. Where it does not, we should not be making the claim.
Reference valuations
Point and mile valuations come from AwardWallet's published point and mile values, used with attribution. Their valuations are derived from a large sample of actual award bookings; their methodology is documented publicly.
Point and mile valuation reference data: AwardWallet, used with attribution. Current snapshot: 2026-08-01. We snapshot these values at build time rather than calling their service on every page view.
Transfer ratios
Ratios are taken from the issuer's own page and re-confirmed by a person on the dates shown. A date advances only when the rule itself was checked.

Programs without an official page listed here are ones whose source we have not yet recorded. Their reference valuations still come from AwardWallet, but we have not linked a primary source for their program rules, and we do not make claims about those rules until we have.
How often this is checked
We run a full data audit monthly: re-read each issuer's transfer page, diff the partner lists and ratios against our data, review any valuation change over 10% by hand, check expiration policies, and re-run validation and link checks before deploying.
Automated checks can flag a difference. They never publish one. See our methodology for why.
If a source has moved or changed
When an official page disappears or changes materially, we keep the previous data row and flag it as needing review rather than silently refreshing its verification date. You will see a warning on any page that depends on it.
