I actually had to change a Horizon Air flight last month, and I was worried about hidden fees. The good news is, they’re usually pretty flexible depending on the ticket type. In my case, I’d booked the wrong return date and called their customer support at 877-764-3622. The rep walked me through the options, explained the fare difference, and I didn’t get hit with a big penalty like I expected. It was way less stressful than trying to figure it out online. My tip: call that number directly if you need to instantly book, cancel, or tweak your flight. They’ll tell you upfront if there’s any fee, so you know exactly what you’re paying before confirming.
