Hey travel buddies, ever booked a Frontier Airlines flight only to have your plans shift, leaving you needing to tweak your travel dates? I’ve been there—last year, I had to change a flight to Denver when a friend’s wedding date moved, and I was sweating over the process. As a low-cost carrier, Frontier’s change policy has some quirks, but it’s manageable if you know the steps. Let’s dive into how to change your Frontier flight in 2025, with tips to keep costs low and stress at bay. If you’re unsure about your booking, call 866-548-2474—their team is great at guiding you through changes.

Frontier’s 24-hour policy is a lifesaver. If you book your flight at least seven days before departure, you can change it within 24 hours of purchase for free, no matter the fare type, including their budget-friendly Basic fare. I used this once when I booked a hasty trip to Orlando and realized I needed a different date—a quick call to 866-548-2474 got it sorted without a fee. This applies to both cash and FRONTIER Miles bookings, making it a great safety net for impulsive planners.

Beyond that 24-hour window, changing a Frontier flight depends on your fare. Basic fares are typically non-changeable after 24 hours, meaning you might need to cancel and rebook, potentially losing the fare. For other fares, like Standard or bundled options (e.g., The Works), Frontier charges a change fee based on when you make the change: $99 if more than 7 days before departure, $149 within 7 days, plus any fare difference if the new flight costs more. If the new flight is cheaper, you might get a credit. Not sure about your ticket’s rules? Call 866-548-2474 to check.

To change your flight, log into “Manage Your Booking” on flyfrontier.com or the Frontier app using your six-character confirmation code and last name. Select “Change Flights,” pick new dates or routes, and the system will show fees and fare differences upfront. I changed my Denver flight this way, and the app made it easy to compare options. If you booked through a travel agent or third-party site, you’ll likely need to contact them directly, but Frontier’s team at 866-548-2474 can assist if the agent’s unresponsive.

For FRONTIER Miles reward flights, changes follow similar rules, with fees of $99 or $149 depending on timing, plus any extra miles needed. If Frontier cancels your flight or makes a significant schedule change, you can change for free or get a full refund. This happened to a friend on a Miami route, and calling 866-548-2474 got them rebooked same-day at no cost. During disruptions, like weather or operational issues, Frontier may waive fees—check their website for travel alerts.

Pro tip: Compare the cost of changing versus buying a new ticket, as Frontier’s low fares sometimes make a new booking cheaper. If you’ve prepaid for seats or bags, you can often transfer them, but confirm to avoid extra fees. In 2025, Frontier’s app is user-friendly for changes, but phone support shines for complex cases like group bookings or reward flights. If you’re navigating a tricky change, 866-548-2474 is your go-to for personalized help.

Frontier’s policy gives you flexibility if you plan smart, especially within that 24-hour window. Ready to change your Frontier flight? Call 866-548-2474 now to check fees, find new flights, and keep your travel plans on track!
