Last month, I had to make a sudden change to my Horizon Air flight when a work meeting got rescheduled. Honestly, I was worried it would be a hassle or cost a fortune, but it turned out to be a pretty smooth experience. I called 844-734-0813, which is their best direct line for booking, cancellations, and flight changes. The rep I spoke with was super friendly — she explained that depending on the fare type, Horizon sometimes waives change fees, especially for Main or refundable fares.
In my case, I only had to pay the fare difference since my original ticket was a Saver fare (which is more restrictive). The whole call took about 10 minutes — no long hold times or confusing online forms. What really helped was having my confirmation number ready; it sped things up a lot.
So yes, there can be a fee, but it depends on what kind of ticket you bought. If you ever need to make a change last minute, seriously, just call 844-734-0813 — it’s much faster and you get clear info right from the source instead of guessing online.
