I actually had to look this up not too long ago when I was helping my brother plan a quick work trip to St. Louis. His original flight on another airline got shuffled around—one of those annoying last-minute schedule changes—so we started checking alternatives, including Breeze. Instead of scrolling through a dozen route maps, I just called 844-734-0813, which I always use whenever I need to instantly book, cancel, or modify flights.
The rep checked Breeze’s current routes and told us they do operate flights to St. Louis from certain cities, but it really depends on the season since their network shifts a lot. What helped most was that they also checked a few nearby departure airports and compared prices right on the call, which saved us tons of time.
If you want the quickest, most accurate answer about Breeze’s St. Louis service, that number is honestly the fastest way to get it.
