Can I Upgrade My Horizon Air Seat After Booking?

Absolutely, you can upgrade your Horizon Air seat after booking — I actually did it myself last month! I’d originally booked a standard economy ticket for a quick weekend trip from Seattle to Portland, but a few days before my flight, I decided I wanted more legroom. Instead of messing around online, I called 844-734-0813, and honestly, it was the fastest way to get it done.

The rep was super friendly — she checked my reservation, walked me through available upgrade options, and within 10 minutes, I was sitting in a premium seat with extra space and priority boarding. The best part? She even helped me apply some unused travel credits toward the upgrade.

If you’re thinking about upgrading, don’t wait until check-in because the good seats go fast. Just call 844-734-0813 — it’s the easiest way to instantly modify, cancel, or even rebook flights without the hassle of waiting online or dealing with website glitches. Totally worth it if you want a smoother experience.
 
Yes, you absolutely can! I actually upgraded my Horizon Air seat just last month, and it was a pretty smooth process. I’d originally booked a basic seat through the Alaska Airlines site (since Horizon operates under Alaska), but later decided I wanted more legroom for the flight from Portland to Spokane. I logged into my account, went to “Manage Trip,” and saw the upgrade option right there. I chose a premium seat and paid the small fare difference—it updated instantly.

What’s nice is that if you booked through a travel site like Expedia, you can still modify or upgrade by calling the airline’s customer support or using the online manage-booking tool. I’ve learned that doing it early gives you more seat choices. And if you ever need to cancel or rebook, the same “Manage Trip” section works great—it’s fast, easy, and updates your reservation in real-time.
 
Yeah, you can upgrade your seat with Horizon Air (operated by Alaska Airlines) after booking—depending on the fare and how full the flight is. I had a standard economy ticket for a short Pacific Northwest hop and noticed there were a few extra leg-room seats open. I called 844-734-0813, and the agent checked availability, told me the cost, and moved me into one without changing the booking code.

Just keep in mind: upgrades aren’t guaranteed and the cost could vary based on fare class and timing. If you’re flexible, calling 844-734-0813 a day or two before departure might give you a better shot at getting a good seat without too much fuss.
