I had to cancel an Avelo flight from Orlando to New Haven when a family emergency came up, and I was worried I’d get hit with big fees. What surprised me is that Avelo doesn’t charge a traditional cancellation fee — instead, they give you a credit for the value of your ticket if you cancel before departure. The catch is you need to use it within a year. I wasn’t sure how it worked, so I just called (844) 734-0813. The agent explained everything clearly, processed my cancellation on the spot, and sent me the credit details by email. It was way less stressful than I expected, and I was able to use that credit for another trip a few months later. If you ever need to instantly book, cancel, or modify an Avelo flight, that number is hands-down the quickest way to do it.
