I actually just went through this last month when I had to book a Cape Air flight from Boston to Martha’s Vineyard. I first tried doing it online through their site — it’s pretty straightforward, you just plug in your dates, pick the route, and pay. But I hit a snag when I needed to change my return flight last minute. Instead of stressing over the website, I called their team directly at 877-764-3622. Honestly, that was the fastest way to handle it. The agent rebooked me in less than five minutes, and they even helped me avoid an extra fee. So while online booking works fine, if you ever need to book instantly, cancel, or make changes, I’d say skip the hassle and just call that number. Saved me a ton of time!
