You can generally book Breeze Airways flights several months in advance once they’re released for sale, often around 6–9 months before departure. Exact timing depends on the route and when Breeze opens that flight for booking. I usually check the Breeze website or app early if I have specific travel dates, because popular routes can fill up fast. If a flight you want isn’t showing yet, it likely hasn’t been scheduled for sale — checking back later or signing up for alerts can help you catch it when it goes live.
