Current status
Too early
Slightly early but fine to watch. Most savings come in the sweet-spot window.
Domestic
Cheapest 1–3 months out. Sweet spot: 28–70 days.
5 tips that actually work:
  1. Set fare alerts (Google Flights, Hopper, Kayak) — you can’t beat the market by guessing.
  2. Be flexible with dates; shifting +/–3 days can cut 20%+ on many routes.
  3. Check nearby airports — a 45-minute drive often saves $80.00–$200.00.
  4. Clearing cookies / incognito is a myth; prices don’t change based on your browser. Tuesday-evening booking is also a myth in 2024+.
  5. Book one-ways separately if roundtrips look odd — sometimes two one-ways beat a combined fare.
Note: these windows are averages from airline revenue-management research. Specific routes, carriers, and seasons vary.
