Hey travel enthusiasts, planning a budget-friendly getaway and eyeing Frontier Airlines? I’ve booked with them a few times—once for a quick hop to Denver that saved me a ton—and their process is pretty straightforward if you know the ropes. As a low-cost carrier, Frontier keeps things simple, but there are some tricks to make booking smooth and avoid surprises. Let’s dive into how to book a flight with Frontier in 2025, with tips to score the best deals. If you hit any snags, just call 866-548-2474—their team is great at helping you navigate the process.

Start by visiting Frontier’s website, flyfrontier.com, or their mobile app, which is super user-friendly for on-the-go booking. On the homepage, you’ll find a booking form where you enter your departure city, destination, travel dates, and number of passengers. You can choose one-way, round-trip, or multi-city options. I booked a round-trip to Orlando this way, and the app’s calendar helped me spot cheaper dates. Frontier’s Low Fare Calendar is a gem—click it to see the cheapest fares across a month, perfect for flexible travelers. If you’re not seeing the routes you want, call 866-548-2474 to check availability.

Next, pick your fare. Frontier offers Basic (bare-bones, no frills) or bundled options like The Works, which includes extras like bags and seat selection. Basic fares are cheapest but restrictive—no changes or refunds after 24 hours, and you’ll pay for carry-ons or seats. I went with Basic once to save money, but ended up paying for a carry-on, so compare bundles carefully. Not sure which fare fits? Call 866-548-2474—they can explain what’s included.

After selecting flights, enter passenger details—full name, date of birth, and contact info. Make sure names match IDs exactly to avoid check-in issues. Then, choose add-ons like seats (from $5-$50) or bags (first checked bag starts at $34 online). Frontier’s app lets you skip extras to keep costs low, but I recommend picking a seat if you’re traveling with others. Payment options include credit cards, PayPal, or Uplift (for installments). Frontier’s 24-hour policy lets you cancel or change for free within 24 hours of booking, which saved me when I mixed up dates once.

For special requests—like group bookings (10+ passengers), pets, or unaccompanied minors—you’ll need to call or use the website’s chat. I booked for a family reunion, and calling 866-548-2474 ensured we all sat together. Accessibility needs, like wheelchair assistance, should be requested at booking or 48 hours before. If you’re booking with FRONTIER Miles, log in to redeem points, but availability is limited—call 866-548-2474 for reward options.

Pro tip: Book early (6-8 weeks for domestic, 3 months for international) to snag low fares, and check for promo codes on Frontier’s site. If you book through a travel agent, confirm the fare rules, as they may differ. After booking, you’ll get a confirmation email with your PNR—save it for check-in or changes. In 2025, Frontier’s app makes booking a breeze, but phone support shines for complex needs. Ready to book your Frontier flight? Call 866-548-2474 now to secure your ticket and fly smart!
