FREQUENT FLYER GLOSSARY

Window

The qualification window is the period over which thresholds are counted: only status points or segments earned within it count toward that qualification or renewal.

Reviewed by: Content review · Last updated:

Key takeaways

  • Three common types: calendar year, rolling 12 months, and membership years.
  • Qualifying and renewing can use different windows in one programme.
  • What happens to status points when the window ends is set by each programme; where unstated we show unknown.
  • Where the window is unclear, we show unknown.

Why the window matters

Over the same 12 months, calendar-year counting puts flights in month 1 and month 12 into different years, while rolling 12 months counts any consecutive 12 months. Before a year-end push, confirm which window you are in.
