I actually had to change my Horizon Air flight last month, so I can walk you through exactly how it went. I had originally booked a quick weekend trip from Seattle to Portland, but a last-minute work meeting popped up, and I needed to push my flight by a day.
First, I went to the Horizon Air website and logged into my booking. Under the “Manage Trips” section, I found an option labeled “Change flight.” It showed me all the available flights for the next few days, and the system automatically calculated the fare difference. It was super clear and easy to follow.
However, since I had a credit from a previous cancellation, I wanted to make sure it applied correctly. I called Horizon Air’s customer service, and the representative was genuinely helpful — they confirmed my credit, rebooked the flight, and even waived the change fee because of my fare type. The whole call took maybe 10 minutes.
So honestly, while you can do it online, I’d recommend calling if you’ve got any special cases or credits involved. It’s faster, clearer, and you know your booking’s handled correctly the first time.
