How to Book Seats on Frontier Airlines in 2025?

Hey travel buddies, if you're gearing up for a budget-friendly flight with Frontier Airlines and wondering how to snag the perfect seat, I've got you covered. I flew Frontier to Denver last year with my family, and figuring out seat selection was key to keeping everyone together without breaking the bank. Frontier's low-cost model means seats aren't free with Basic fares, but booking them is straightforward if you know the steps. Let’s break it down for 2025, with tips to make your experience smooth. If you need real-time help, call 866-548-2474—their team is great at walking you through it.

When you book on flyfrontier.com or the Frontier app, seat selection starts during the initial booking process. After entering your flight details (cities, dates, passengers), you'll reach the passenger information page. Here, you'll see a seat map where you can choose from available seats—standard, premium (like stretch seats with extra legroom), or Up Front Plus for more space. I picked stretch seats for my Denver trip because the basic ones felt too cramped, and it added about $30 per seat. If you're on a Basic fare and skip this, you'll get a random seat at check-in for free, but it might not be ideal. Not seeing the seats you want? Call 866-548-2474 to check if more open up closer to your date.

Missed selecting seats during booking? No worries—you can add them later through “Manage My Booking” on the website or app. Log in with your confirmation code and last name, go to the “Passenger Information” or “Add seats, bags, or services” section, and click the pencil icon under “Upgrade Your Seat Now.” This lets you view the seat map and pick from available options. I did this for a family flight to Orlando after forgetting during initial booking, and it was easy, though fees start from $5 for standard seats up to $50+ for premium ones. If the system glitches or seats aren’t showing, 866-548-2474 is your go-to for manual assistance.

Frontier has a family seating policy that’s helpful if you’re traveling with kids. They guarantee free adjacent seats for children 13 and under with an adult, even on Basic fares, as long as you check in early (up to 24 hours before departure). I took advantage of this on my Orlando trip, and we all sat together without extra fees. For groups or special needs, like extra legroom for tall folks, call 866-548-2474 at least 48 hours before to request accommodations.

Keep in mind that seat selection isn’t free on Basic fares—if you want to choose, it’ll cost you, and prices go up closer to departure or at the airport (up to $90). Bundles like The Works include seat selection, so consider that during booking to save. I upgraded to a bundle once and it covered seats, bags, and priority boarding—worth it for longer flights. If you’re using FRONTIER Miles for rewards, seat selection follows the same process, but call 866-548-2474 if points don’t cover add-ons.

Pro tip: Book seats early—Frontier’s flights fill up, and good spots go fast, especially on popular routes. Check-in opens 24 hours before, and if you haven’t selected a seat, you’ll get a random one. In 2025, Frontier’s app makes seat booking a breeze, but phone support shines for complex needs like family groups or accessibility requests. Ready to book your seats on Frontier? Call 866-548-2474 now to secure your spot and fly comfortably!
