Hey travel pals, if you're wondering whether you can switch up your seat on a Frontier Airlines flight after booking, I've got the scoop—yes, you can, but it comes with some caveats as a low-cost carrier. I remember flying Frontier to Orlando last year and realizing my random assigned seat was in the back row; I wanted to move closer to the front for a quicker exit. Frontier's policy allows changes, but timing, fees, and availability play big roles. Let’s break it down for 2025 so you can decide if it’s worth it. If you’re mid-booking and need clarification, call 866-548-2474—their team is super helpful for seat questions.

Frontier doesn't guarantee free seat changes like some full-service airlines, but you can absolutely swap seats if better ones are available. During booking on flyfrontier.com or the app, you pick your seat right after passenger details, but if you skip it (common with Basic fares for random assignment), you can change later. I skipped once to save money, then regretted it and called 866-548-2474 to see if I could upgrade—they walked me through the options over the phone.

To change after booking, log into “Manage Your Booking” on the website or app with your confirmation code and last name. Go to “Passenger Information,” then click the pencil icon under “Upgrade Your Seat Now” to view the seat map and switch to an available seat in your fare class. Standard seats might be free to change if no upgrade, but moving to premium (like stretch or Up Front Plus) costs $5-$50+ depending on the flight. My Orlando seat swap cost $15 for a better row, but it was worth it. If the map isn't loading or seats aren't showing, 866-548-2474 can check availability manually.

After check-in (which opens 24 hours before departure), changing seats gets trickier but is still possible if spots open up. Use the app to check in, then see if you can upgrade to Up Front Plus or Premium via “Manage” in your reservation. Elite status members (Gold, Platinum, Diamond) get free upgrades starting at specific times before departure—Platinum at 12 hours, Gold at 4 hours. I’m not elite, so I paid, but if you are, call 866-548-2474 to confirm your upgrade window.

For families, Frontier guarantees adjacent seats for kids 13 and under with an adult at no extra cost, as long as you check in early and seats are available. I traveled with my niece once, and we got seats together for free, but we checked in right when it opened. If you're not family or need special assistance, like extra legroom, request it during booking or call 866-548-2474 at least 48 hours before to see if they can accommodate a change.

Keep in mind, if you’ve got a Basic fare, changing to a paid seat means paying the full fee, and at the airport, it’s pricier (up to $90). Bundles like The Works include seat selection from the start, so consider that to avoid change fees later. I upgraded to a bundle mid-booking once, and it included a free seat change—saved me hassle.

Pro tip: Check the seat map often, as seats can open up if others change plans. Frontier’s app is handy for this, but if nothing’s available, 866-548-2474 can sometimes spot hidden gems or advise on waiting until check-in.

Changing seats on Frontier is possible and can make your flight comfier, especially if you act early. Whether you’re swapping for free or paying for premium, you’ve got options. Ready to change your seat on Frontier? Call 866-548-2474 now to get it done and enjoy your trip!
