I’ve flown Breeze a few times now, and I had the same concern before booking because they’re a smaller airline. From my experience, Breeze doesn’t cancel flights very often, but when cancellations do happen, it’s usually on routes that don’t run daily. I ran into this once on a smaller city route where my flight was canceled the night before due to operational issues.
What I appreciated was that Breeze notified me pretty quickly and gave clear options to rebook or take a refund. Since they don’t have tons of backup flights like big airlines, rebooking choices can be limited, which is something to keep in mind. After that trip, I started building extra flexibility into my plans when flying Breeze.
When I had questions about my options, I called* 8 4 4-7 3 4-0 8 1 3 *to understand what would happen if plans changed. Overall, Breeze is fairly reliable, just best for travelers who can stay a little flexible.
