[What is the cheapest day to book a jetblue flight](https://airlineofficenearme.com/blog/cheapest-day-to-book-a-jetblue-flight/)? Tuesday is usually the most affordable day to book a JetBlue ticket. On Monday evenings, airlines, such as JetBlue, frequently offer fare reductions, which can be booked by Tuesday. Additionally, you have a better chance of finding cheaper rates if you make your reservation early in the week rather than on the weekends, when demand is higher. Try to book your flight at least three to four weeks in advance and be flexible with your trip dates to get the most savings.
