Hey folks, last spring I scored a steal on JetBlue from BOS to SFO—booked on a Tuesday and saved ~35% vs weekend prices. Was eyeing a family reunion, found fares drop midweek.Cheapest day to book JetBlue flights? Hands down Tuesday or Wednesday. Airlines like JetBlue tweak prices Sundays/Mondays, so wait 48 hours for sales. I use their app's flexible dates tool—shows calendars with lowest rates. Best way: Set fare alerts Tuesday AM, book by Thursday before hikes. Avoid Fridays/Saturdays (peak pricing). Pro tip: Midnight bookings sometimes snag extras. Turned my $650 trip into $420—game-changer for budget travel!
