Step-by-Step: How to Check-In for Frontier Airlines

We know traveling can sometimes feel like a lot, especially if you’re doing it all by yourself or for the first time. That’s why we’re keeping things simple. Here’s everything you need to know about the steps to check in for Frontier Airlines—all broken down in a friendly, beginner-friendly way.

Step 1: Know When the Frontier Check-In Window Opens

Before you do anything, you need to know when you can check in.

The Frontier check-in window opens 24 hours before your flight’s departure. It closes 60 minutes before the flight for domestic travel and 2 hours before for international flights.

Tip: Set a reminder on your phone when it’s 24 hours before your flight. That’s your green light to begin!

Step 2: Choose Frontier Online Check-In for Convenience

The easiest way? Frontier online check-in.

You can check in directly on the Frontier Airlines website or through their mobile app. If you’ve ever waited in a long airport line and wished you could skip it, this is your chance!

Here’s how you do it:

Go to Frontier’s site or app.
Click “Check-In.”
Enter your confirmation code and last name.
Follow the instructions.

That’s it-you’re almost done already!

Step 3: Add Baggage (If You Have Any)

Frontier is a low-cost airline, so bags usually aren’t included in your ticket.

During online check-in, you can:

Add carry-on or checked bags.
Pay for them in advance (it’s cheaper than at the airport).

Example: If you're taking a weekend trip with just a backpack, you might not need to add a bag. But if you’re visiting family for a week, you probably will.

Step 4: Choose or Change Your Seat (Optional but Helpful)

You might be assigned a random seat, but if you want to sit with your travel buddy or near the front, you can select a seat during check-in.

Frontier charges for seat selection, but many travelers feel it’s worth the small cost for peace of mind—especially on longer flights.

Step 5: Consider Priority Check-In Frontier for a Smooth Airport Experience

If you hate waiting in lines, you might want to upgrade to priority check-in Frontier.

What is that?

You get a separate line for check-in at the airport.
Faster bag drop.
Earlier boarding group.

It’s a small upgrade that can feel like a big relief when you’re short on time or traveling with kids.

Step 6: Get Your Boarding Pass

Once you’re checked in, you’ll get your boarding pass. You can:

Download it to your phone.
Print it at home.
Pick it up at the airport kiosk.

Tip: Having your boarding pass ready on your phone is super handy, especially if you’re traveling light and heading straight to security.

Step 7: Arrive at the Airport on Time

Even after checking in, timing at the airport still matters.

Here’s what to aim for:

Arrive 2 hours before domestic flights.
Arrive 3 hours before international flights.

This gives you enough time to go through security and find your gate without stress—even if there are lines.
