The best time to book a flight is usually several weeks or months before your travel date. For domestic flights, booking 1 to 3 months in advance often helps secure better prices, while international flights are usually cheaper when booked 2 to 6 months early. Midweek bookings, especially on Tuesdays and Wednesdays, often offer lower fares compared to weekends. Traveling during off-peak seasons can also help save money. Avoid last-minute bookings, as prices tend to rise closer to departure dates. Comparing fares, setting price alerts, and being flexible with travel dates are smart ways to find the best flight deals.
