Why did flights disappear after I refreshed?

Award space is dynamic and can change minute-to-minute. If results vanish after a refresh, one of these likely happened:

Someone booked the seats before your refresh.
Airline pulled back inventory (happens often close to departure).
Cached → live change: A fresh check showed different availability than the earlier cached snapshot.
Filters hiding results: Nonstop-only, specific cabins, airlines/programs, or tight duration limits can remove matches.
Married-segment logic changed: Some airlines only release space when specific segments are booked together; a re-check may break that combo.
Dynamic-price filter kicked in: If a program repriced an award above our threshold, we’ll hide it to avoid showing unusable options.
Session/timeouts on airline side during validation.

Run a Live search (or confirm on the airline site) to see what’s bookable right now.
Widen the search: add nearby airports, expand dates, allow connections, or relax cabin/airline filters.
Re-run with fewer filters to rule out hidden results.
Set an alert so we’ll notify you if those seats (or similar) return.

Always confirm before transferring points—availability can change between checks.
