Where each rule is written

No aggregator, no forum thread, no post from 2019. Four of the eleven are below; each program page carries its own source and date.

When a rule is pending, ambiguous, or the airline quietly pulled it, we say that on the page instead of rounding up. Some links here may earn us a commission. It never changes what we verify, how we rank a program, or what we call free.
