JetBlue does not have a specific day of the week for lowering prices. Instead, fare changes occur based on demand, market trends, and promotional strategies. To find the best deals, frequently check JetBlue’s Deals page and sign up for their email alerts to stay updated on sales and special offers. Additionally, follow JetBlue on social media for announcements of flash sales and limited-time promotions. For the best fares, use fare comparison tools, book your flights early, and be flexible with your travel dates to take advantage of lower prices when they are available.
