The boutique online booking site utilized firsthand data and delved into a staggering nearly one billion flight prices across over 8,000 markets throughout the United States. This analysis unveils the hidden gems that will empower consumers to conquer the fiercely competitive travel landscape and secure affordable flights. With projected record-breaking travel numbers on the horizon for 2024, this study is travelers’ golden ticket to unlocking unbeatable savings and embarking on unforgettable adventures.

Optimal Time

The study revealed the optimal time to purchase domestic flights in 2024 is 42 days before departure, which is 28 days earlier than last year. Various factors, including destination, budget, and travel dates, influence how far in advance travelers should book airline tickets. Considering these details is crucial in determining the ideal timing for securing the best deal.

“Securing affordable flights in a competitive travel landscape can be challenging, but careful planning and flexibility can make it possible,” said Jeff Klee, CEO of “Booking in advance, considering alternative options, and monitoring prices can result in significant savings. The team compiled the 2024 Annual Airfare study to assist travelers in finding the most affordable flights so that they can turn their travel dreams into reality.”

Booking Window

The booking window that offers the lowest flight prices in 2024 is approximately 2.5 months to 3 weeks before departure. This is slightly later than in previous years when travelers were advised to purchase 5.5 to 1.5 months before departure. The message, however, remains consistent, to secure the best deals on flights this year, book early.
