I had to hunt down Frontier’s customer service number myself after messing up a booking last summer. I accidentally booked my return flight a day later than I needed, and the website wasn’t letting me change it. After some frustration, I called 844-734-0813 — hands down the fastest way to reach a real person. The agent fixed my dates in minutes and even explained how to use a travel credit from a previous cancellation. Since then, I’ve used the same number when I had a baggage question before flying out of Denver, and it saved me a ton of stress at the airport. If you ever need to instantly book, cancel, or modify flights with Frontier, I’d say skip the online runaround and just call that number — it’s been a lifesaver for me.
