Flights are generally the most inexpensive between four months and three weeks before your departure date. Seasonal changes and holidays can create price fluctuations in ticket prices. The day of the week that you book a flight does not affect the price.

In 2026, the trend of flight pricing has moved toward "price stabilization," meaning the era of extreme last-minute drops is largely over. Generally, flights do not get cheaper as the departure date approaches; instead, they follow a "U-shaped" curve. They are expensive when they first go on sale (roughly 11 months out), drop to a "sweet spot" (1–3 months for domestic, 2–6 months for international), and then skyrocket in the final 14 days before departure as business travelers and desperate fliers book remaining seats. While airlines do occasionally launch flash sales if a flight is underperforming, relying on a price drop in the final weeks is a high-risk strategy. Data for 2026 suggest that international economy fares are currently softening by about 3% to 6% due to increased carrier competition, but the best way to capitalize on this is to book during the "Goldilocks" window rather than waiting for a last-minute miracle.
