I actually ran into this exact issue a few months ago when I accidentally misspelled my last name on a Horizon Air ticket — just one letter off, but it caused a lot of stress! I found out that you can’t just fix it online if the name doesn’t perfectly match your ID. I called Horizon Air’s customer service right away, explained the mistake, and they corrected it within minutes after verifying my details. The rep said minor typos are common and can usually be fixed without canceling your ticket. If it’s a bigger error (like a full name change), they might need to reissue the ticket. My advice? Always double-check your name when booking, and if you spot an error, contact the airline’s helpline immediately — it’s by far the fastest way to modify, cancel, or even rebook your flight before it becomes a check-in problem.
