Booking Tips

Best Time to Book Flights

Q: Is it cheaper to book flights last minute?

Rarely. On most routes, last-minute fares (less than 2 weeks out) are 30–50% higher than the same seat booked 4–6 weeks earlier. Exceptions exist on routes with excess capacity.

Q: What is the cheapest month to book flights?

January and February are typically the cheapest months to book for travel. Airlines sell heavily after the holiday season ends. August and September are also discounted for off-peak fall travel.

Q: Does booking further in advance always get a cheaper fare?

No. Booking too far in advance (6+ months for domestic) often means paying the initial release price before sales and discounts appear. The sweet spot varies by route but is usually 4–12 weeks.

Q: When should I stop waiting and just book?

If you are within 4 weeks of your departure date and have not booked, book immediately. The risk of fares rising further outweighs the potential savings from waiting for a lower price.

Book domestic flights 1–3 months in advance for the best prices. For international travel, 2–6 months ahead is optimal. Prices rise sharply in the last 3 weeks before departure. January and February offer the lowest published fares of the year.
