I had to change a Horizon Air flight last-minute when a work meeting got pushed back, and honestly, I thought it would be a nightmare. The app wasn’t cooperating, so I just called 877-764-3622. A rep picked up right away, walked me through the options, and I had a new ticket in less than 10 minutes. Way smoother than trying to juggle it online. I’ve used that number a couple of times since—whether booking or tweaking travel plans—and it’s hands-down the quickest way to get things sorted without the stress.
