Yes, you can change a flight on Frontier — I had to do it myself when a work trip to Denver got moved up a day. At first, I tried messing around with the website, but it was glitchy and I didn’t want to accidentally lose my booking. I called 844-734-0813 instead, and honestly, it was the easiest part of the whole trip. The rep explained the change fees, gave me a couple of flight options, and had the new ticket in my inbox within minutes. I paid less because I wasn’t changing super last-minute, which was a relief. If you ever need to instantly book, cancel, or modify a flight, I’d skip the stress and just use that number — it saved me both time and money.
