Traveling with Frontier Airlines can be a smooth and efficient experience especially when you’re well-prepared and understand their check-in process and timing guidelines. One of the most common questions travelers ask is: “How early should I check in for my Frontier flight?” Whether you're flying domestically or internationally, the check-in process plays a crucial role in ensuring that your journey starts off right. Here's everything you need to know.
Frontier Airlines Check-In Timeframes
Frontier Airlines provides passengers with several convenient options to check in, but all methods are bound by specific timeframes that must be followed closely to avoid issues like missed flights or forfeited tickets.
Online and Mobile App Check-In
Frontier’s online check-in and mobile app check-in open 24 hours before your scheduled flight departure and remain available until 60 minutes before takeoff. This is the recommended method for most passengers, as it helps avoid long lines at the airport and gives you more control over your time. During online check-in, you can:[1_866 551 1186

Choose or upgrade your seat
Pay for baggage
Download or print your boarding pass
This process is not only quicker but also often comes with lower service fees compared to checking in at the airport.
Airport Counter Check-In
For passengers who prefer to check in at the airport or are required to do so (such as unaccompanied minors or those needing special assistance), the airport counters open approximately two hours before flight departure. However, they close 60 minutes prior to departure, so you must complete your check-in and bag drop before this deadline.
It's important to keep in mind that checking in at the airport may incur additional service charges. Moreover, lines can be long, particularly during peak travel hours, holidays, or weekends so arriving early is essential.
Bag Drop and Boarding Deadlines
Checking in is just one part of the process. If you're traveling with checked baggage, there are additional time considerations to be aware of.
Checked Bags
If you have checked luggage, Frontier recommends arriving at the airport at least two hours before your flight. The reason? The bag drop counter, like the check-in desk, closes exactly 60 minutes before departure. Missing this deadline means you won’t be able to check your luggage, which could result in missing your flight altogether.
Boarding Gate Arrival
After checking in and dropping off any bags, it’s time to proceed through security and head to your boarding gate. Frontier strongly encourages all passengers to be at the gate at least 45 minutes before departure. Boarding begins well in advance of takeoff and closes 20 minutes before the scheduled departure time. If you're not at the gate on time, you risk being marked as a no-show, and your ticket may be forfeited without a refund.
Recommended Arrival Times at the Airport
To ensure you meet all of Frontier’s check-in and boarding deadlines, the airline offers the following arrival time recommendations:
For domestic flights: Arrive at the airport at least 2 hours before your flight.
For international flights: Arrive at least 2–3 hours before departure, as customs and security processes may take longer.
These buffers give you enough time to handle check-in, security screening, finding your gate, and addressing any unexpected issues or delays.
Why It’s Important to Check In Early
Checking in early, especially via the Frontier app or website, can offer several advantages:
Avoid Long Lines: Airport counters and kiosks can become crowded, especially during busy travel periods.
Save Money: Frontier charges extra fees for many services at the airport. Checking in online can help you avoid these added costs.
Secure Your Seat: Seat selection availability may be limited closer to the departure time. Early check-in allows more options.
Time to Handle Issues: If any problems arise like a name mismatch on your ticket or baggage payment issues—you’ll have time to resolve them without panic.
Peace of Mind: There’s comfort in knowing you’re all set before heading to the airport. Checking in early lets you focus on the rest of your travel preparations.
Check-In Options at a Glance
Here’s a quick comparison of Frontier’s check-in methods:
Check-In Method Opens Closes Best For
Online / Mobile App 24 hours before departure 60 minutes before departure Most passengers looking to save time and money
Airport Counter 2 hours before departure 60 minutes before departure Passengers needing assistance or traveling with special circumstances
Self-Service Kiosks (where available) 2 hours before departure 60 minutes before departure Those who prefer in-person check-in but want a faster option than the counter
Missed the Deadline? Here’s What Happens
If you fail to check in on time or arrive at the gate late, you may be marked as a no-show, which generally results in your reservation being canceled. Frontier's policies are strict about these timelines, and refunds are typically not issued for missed flights due to late check-in or boarding.
To avoid these situations, set a reminder when your 24-hour check-in window opens. Most smartphones allow for notifications or alarms, making it easy to plan ahead.
