Plans shift. Whether it’s a schedule conflict, a missed connection, or a last-minute change of heart, knowing how to adjust your Frontier Airlines reservation without a headache makes all the difference. Frontier gives passengers several tools—both online and through its mobile app—to manage bookings, change flights, and stay in control of their trip.
The “Manage Booking” feature on Frontier’s website is your go-to for making updates to your reservation. Once you’ve booked a flight, you can return at any time to:
Add or remove bags
Change seats
Update traveler info
Cancel or rebook a flight
Check your flight status
All you need is your last name and confirmation code to get started.
Booked your flight through Google Flights or another third-party site? No problem. As long as the ticket was issued by Frontier, you can still manage your trip directly on their site or app.
When you book with Frontier, you’ll get a six-character confirmation code. Don’t lose it—it’s your ticket to managing everything from check-in to last-minute changes.
If you misplaced the confirmation email, you can look up your reservation using your name and travel dates in the Frontier app or website. The app is especially handy if you want mobile check-in, gate alerts, or updates if your flight changes.
Whether you want a different departure date, time, or even destination, Frontier’s flight change system lets you make adjustments without canceling your trip altogether.
Here’s how it works:
Go to the “Manage Booking” page
Enter your confirmation code and last name
Select the flight you want to change
Pick your new flight
Pay any fare difference or applicable fees
Changing flights is easier (and often cheaper) the earlier you do it. Waiting until the last minute usually means fewer options and higher fees.
Fees vary based on when you make the change and what type of fare you booked.
You’ll likely pay a fee if:
You’re past the 24-hour free change window
You have a basic fare with no added flexibility
You’re changing close to departure
That said, if you booked a “Works” bundle, you can make changes—or even cancel—without paying extra. The Works bundle also includes benefits like refundability and priority boarding.
Yes—under the right conditions:
You’re within 24 hours of booking and your flight’s at least 7 days away
You bought a flexible fare or added the Works bundle
Frontier significantly changed your flight time
If you fall into any of these categories, you won’t have to pay a change fee. But timing matters. If you know something’s come up, act fast.
Sometimes, Frontier changes flight times on its end. When that happens, they’ll usually notify you by email or app alert.
If the change is minor—say, 10 or 15 minutes—you’re likely stuck with it unless you want to pay to switch. But if the shift is significant (several hours or a different day), you can often choose an alternate flight for free.
Here’s what to do:
Log into your reservation
Review the new flight details
Choose to accept the change or select a new flight
It’s a good idea to act quickly once you’re notified—availability can disappear fast.
Frontier lets you change your flight for free within 24 hours of booking, as long as the flight is at least seven days away. This grace period is especially useful if you booked impulsively or found a better schedule shortly after confirming.
To make a change:
Use the “Manage Booking” tool
Find your flight and click “Change”
Make your update
Confirm any fare difference
Even if you booked through a third party, you can still make changes on Frontier’s site—as long as the ticket was issued directly by them.
If you’re on the go, the Frontier app is the fastest way to handle flight changes and booking updates. With it, you can:
Add bags or pick new seats
Check your flight status
Access your mobile boarding pass
Get instant alerts for delays or gate changes
It’s a solid tool if you’re mid-trip or handling last-minute shifts.
Most booking changes can be handled online or through the app. But if you’ve missed a flight, need same-day rebooking, or have a complicated issue, calling might be the better option.
That said, Frontier’s phone support isn’t always available 24/7. You’ll often get quicker results using the self-service options on the website or app.
Managing a Frontier Airlines booking doesn’t need to be frustrating. Whether you’re switching flights, adding bags, or rebooking after a schedule change, the tools are there—you just need to use them the right way.
Remember:
Act fast if plans change
Know your fare rules
Use the 24-hour window to your advantage
Check the app regularly for updates
Only call if the situation really needs it
Staying flexible and proactive puts you in control, even when your plans don’t go as expected.
