How Do I Check In on Frontier Airlines?
Traveling can be exciting, but let’s be honest—airport lines and last-minute surprises aren’t anyone’s idea of fun. One of the easiest ways to keep your trip on track (and avoid stress) is to check in for your flight ahead of time. If you're flying with Frontier Airlines and wondering how to do that, you’re in the right place.
In this post, we'll walk you through how to check in with Frontier, what you'll need, and how tools like Frontier Airline manage booking can help you stay one step ahead of travel-day chaos.
When and How to Check In with Frontier Airlines
You can check in with Frontier Airlines online as early as 24 hours before your scheduled departure, and up to 60 minutes before your flight takes off. If you're traveling internationally, check-in usually closes 60–90 minutes before the flight, depending on the destination.
There are three main ways to check in:
1. Online Check-In (Recommended)
This is the fastest and most convenient option. Just go to flyfrontier.com and click on “Check-In.” You’ll be asked for your last name and confirmation code (from your booking).
Once you're in, you can:
- Confirm or change your seat
- Add bags or pay for carry-ons
- Purchase priority boarding
- Print or email your boarding pass
2. Mobile App
If you're more of an on-the-go traveler, the Frontier Airlines app makes check-in easy from your phone. You’ll also get mobile boarding passes and flight notifications.
3. Airport Kiosk or Counter
If you prefer doing things in person—or just didn’t get around to checking in online—you can use the kiosks at the airport. But keep in mind, Frontier Airlines check-in lines can get long, and there may be a fee if you wait until the last minute to check a bag.
Use Frontier Airline Manage Booking Before You Check In
Before you check in, it’s a good idea to head over to the Frontier Airline manage booking section of the website. This is where you can review your flight details, select a seat if you haven’t yet, or make changes to your itinerary.
Need to change your flight time or add baggage? You’ll do it here. The Frontier Airline manage booking tool keeps everything in one place, which can save you from last-minute headaches at the airport.
What You’ll Need to Check In
Before you start, make sure you have:
- Your booking confirmation number
- Your last name as it appears on your reservation
- Any ID or passport details (for international travel)
If you’ve made your reservation through a travel agency or third-party site, it’s still best to check your flight through Frontier Airlines reservations directly, to make sure everything is accurate and up to date.

That said, if it’s something simple like adding a bag or viewing your boarding pass, it’s often quicker to do it yourself through the app or Frontier Airline manage booking page.
What About Baggage?
Let’s face it—bags can be a pain. If you’re unsure what you’re allowed to bring, the Frontier airlines manage booking faq baggage section on their site is worth checking out. It lays out everything you need to know, including:
- What qualifies as a personal item
- Size and weight limits for carry-ons and checked bags
- Fees for each type of baggage
- Special item handling (like strollers or sports gear)
Frontier’s fees are usually lowest if you pay online during check-in—so it’s smart to take care of this early.
