I don't think i should have paid extra for my flight, because i didn't know that American Airline in Kona, HI. was going to be closed. I tried calling to make changes but with new business hours I had to wait for open hours. I waited until it was 2am in Hawaii because cheapoair doesn't open 'til 8am est time. So I was tired. I had a cooler of frozen food that need to be on that flight. They were melting. I was desperate to get home. I needed to get back to work. So I missed work Friday. Its not right that I had to pay almost $300 for a new flight. User's recommendation: make sure your airline is open because Cheapoair will not tell you.
