Booking Decision Checklist
Before the window
If your trip is still more than 47 days away, treat this read as a watch signal. Compare the live fare against the recent range, set an alert, and avoid locking a flexible trip unless the current price is already well below the route pattern.
Inside the window
From 33-47 days out, the page shifts from monitoring to decision support. A publishable fare near the lower percentile is a stronger buy cue; a thin or recalibrating read means keep the route page open and verify dates before checkout.
