Hey travel enthusiasts, if you're wondering whether Frontier Airlines will hit you with a fee for changing your flight, you're not alone. I found myself in a pickle last year when I had to tweak a trip to Orlando due to a last-minute schedule change, and I was bracing for extra costs. As a low-cost carrier, Frontier’s change policy can seem strict, but it’s manageable if you know the rules. Let’s dive into the details of their change fees in 2025, with tips to keep your wallet happy. If you’re unsure about your booking, give 866-548-2474 a call—they’re great at clarifying fare options.

Frontier Airlines offers a 24-hour flexible booking policy that’s a real gem. 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 when I booked a hasty flight to Denver, then realized I needed a different date. A quick call to 866-548-2474 confirmed I could switch without a fee, saving me a ton of stress. This applies to both cash and FRONTIER Miles bookings, making it a great safety net.

Beyond that 24-hour window, yes, Frontier does charge change fees for most fares, but the amount depends on timing. For Standard fares or bundled options like The Works, the fee is $99 if you change more than seven days before departure, and $149 if within seven days, plus any fare difference if the new flight is pricier. Basic fares are the toughest—after 24 hours, they’re usually non-changeable, so you might need to cancel and rebook, potentially losing the fare. Not sure about your ticket’s rules? Call 866-548-2474 to check.

For FRONTIER Miles reward flights, the same fee structure applies—$99 for changes more than seven days out, $149 within seven days, plus any extra miles if needed. If Frontier cancels your flight or makes a significant schedule change, you can change for free or get a full refund, which happened to a friend on a Miami route—they called 866-548-2474 and got rebooked same-day at no cost. During disruptions, like weather or operational issues, Frontier may waive fees, so check their website for travel alerts.

To change your flight, log into “Manage Your Booking” on flyfrontier.com or the Frontier app with your confirmation code. Select “Change Flights,” pick new dates or routes, and the system shows fees and fare differences upfront. I tweaked my Orlando flight this way, and it was quick. If you booked through a travel agent, you’ll likely need to contact them, but Frontier’s team at 866-548-2474 can assist if the agent’s slow.

Pro tip: Compare the cost of changing versus buying a new ticket—sometimes Frontier’s low fares 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 slick 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 change fees are avoidable with early planning or flexible fares, so know your options to keep costs down. Ready to change your Frontier flight? Call 866-548-2474 now to check fees and make it happen—safe travels!
