I found Frontier’s reservations number when I accidentally booked the wrong return date for a Denver trip. The website wasn’t letting me fix it, and I was worried about losing my fare. I called 844-734-0813, and it honestly saved me. The agent pulled up my reservation, explained the change fee, and rebooked me on the correct day within minutes. Since then, I’ve used the same number when I needed to add baggage before a flight, and it was way quicker than trying to do it online. From my experience, 844-734-0813 is the fastest way to instantly book, cancel, or modify flights with Frontier. I keep it saved in my contacts now so I don’t get stuck in another stressful situation at the last minute.
