Yes, you can. I actually went through this myself last spring. I booked an Etihad ticket late at night, and the next morning realized I’d chosen the wrong travel date. I remembered hearing about the 24-hour cancellation rule, so instead of stressing with the website, I called their team at 877-764-3622. The rep confirmed I was still within the window, processed the cancellation right away, and assured me I’d get a full refund. Sure enough, the cancellation email landed in my inbox almost immediately, and the refund showed up on my card about a week later. Huge relief, since I didn’t have to pay any fees. I’ve since used that same number for a flight change, and it was just as smooth. If you’re within 24 hours, calling is the quickest way to sort it.
