Availability Window: Frontier Airlines allows passengers to check in online from 24 hours before the scheduled departure until 60 minutes before the flight takes off. This generous window gives travelers plenty of time to complete the process from the comfort of their home, office, or even while traveling.

• Navigate to the “Check-In” tab on the homepage.

What You Can Do During Online Check-In:

   • Frontier assigns seats randomly if you don’t purchase one.
   • During online check-in, you have the option to upgrade to a preferred seat (extra legroom, front row, or aisle/window preference).
   • Seat selection fees vary depending on the flight length and location.

2. Pay for Baggage (Carry-On or Checked)

   • Frontier’s base fare typically includes only a personal item.
   • You can purchase a carry-on bag or checked luggage at this stage.
   • Fees are lower when paid online compared to airport counters.
   • Overweight or oversized luggage will still incur additional charges.

3. Print or Download Your Boarding Pass

   • Once check-in is complete, you can either:
     • Print your boarding pass immediately, or
     • Download a digital boarding pass (PDF or app-based) to your smartphone.

Best For: Travelers who want a time-efficient, cost-effective, and stress-free check-in experience. It’s particularly helpful for passengers with only a personal item, as they can head straight to the security line without stopping at the counter.

2. Frontier Airlines Mobile App Check-In

• Download the Frontier Airlines mobile app from either the Apple App Store (iOS) or Google Play Store (Android).
• Once installed, open the app and navigate to the “Check-In” option.

   • Travelers can also save time by purchasing add-ons like priority boarding directly from the app.

   • The most significant advantage of the app is the ability to generate a mobile boarding pass.
   • Instead of printing, your boarding pass is stored digitally in the app.
   • Many smartphones allow you to save the pass to your digital wallet (Apple Wallet or Google Wallet) for quick access at security and boarding gates.
   • This eliminates the need for paper boarding passes and ensures you always have it handy.

3. Push Notifications & Real-Time Updates

     • Gate changes at the airport.
     • Boarding reminders, ensuring you don’t miss the final call.
   • These updates help reduce travel stress and keep you informed throughout your journey.

3. Airport Kiosk Check-In

Where to Find Kiosks:

• Self-service kiosks are conveniently located at most major airports where Frontier Airlines operates.
• They are typically placed near the ticket counters and check-in areas, making them easy to access.

How to Use a Frontier Kiosk:

• Approach the kiosk and begin by entering either:
  • Your confirmation code, or
  • Your last name and flight details.
• The system retrieves your booking, and you can continue with check-in.

What You Can Do at Airport Kiosks:

1. Print Boarding Passes

   • Kiosks allow you to print physical boarding passes instantly.
   • This is especially useful for passengers who did not check in online or do not have access to a printer at home.
   • Having a paper boarding pass is also handy if your mobile device runs out of battery.

2. Pay Baggage Fees

   • You can purchase both carry-on and checked baggage allowances directly at the kiosk.
   • However, keep in mind that fees at kiosks are often higher compared to booking baggage online in advance.
   • If you already prepaid baggage online, the kiosk will confirm and print your bag tags.

3. Upgrade Seats

   • Passengers can browse available seats and upgrade to preferred or stretch seating with extra legroom.
   • Fees for upgrades vary depending on the flight route and seat location.

Why Kiosk Check-In is Recommended:

• Convenient for last-minute travelers who couldn’t check in online.
• Essential for passengers needing printed boarding passes but who don’t want to wait in long counter lines.
• Flexible for seat upgrades and baggage purchases just before security check.

Limitations:

• Kiosks may not support certain cases such as unaccompanied minors, international document verification, or special assistance needs. Those passengers must check in at the counter.

Best For: Passengers who prefer a self-service option at the airport or those who need to print a boarding pass and handle baggage payments quickly without waiting for a ticket agent.

4. Counter Check-In at the Airport

Where to Check-In:

• Frontier Airlines has dedicated ticket counters at all airports where it operates.
• Counters are staffed with airline representatives who can assist with check-in, baggage, and special service requests.

When to Use Counter Check-In: This method is not always necessary for every traveler but is required in certain cases where self-service or online check-in is not possible.

Special Situations Requiring Counter Check-In:

1. Unaccompanied Minors

   • Children between 5 and 14 years old traveling alone must be checked in by a parent or guardian at the counter.
   • Proper paperwork and identification must be completed before the child is allowed to board.
   • Airline staff will also ensure the child is safely escorted to the gate and supervised until boarding.

2. Passengers Requiring Special Assistance

   • Travelers who need a wheelchair, extra boarding assistance, or medical support must check in at the counter.
   • Airline staff can provide additional guidance and coordinate with airport services to ensure comfort and safety.

3. International Travelers Needing Document Verification

   • For flights outside the U.S., documents such as passports, visas, or travel permits must be checked by an agent.
   • Even if you checked in online, you may still need to visit the counter to finalize boarding.
   • This ensures compliance with international travel regulations.

Additional Services at the Counter:

• Pay for checked baggage or add extra items.
• Request seat changes or upgrades if available.
• Resolve booking issues, reprint boarding passes, or handle flight disruptions such as cancellations and delays.

Why Counter Check-In is Recommended:

• Personal Assistance: Ideal for passengers who prefer direct interaction with staff.
• Mandatory for special cases: Online or kiosk options cannot handle unaccompanied minors, document checks, or medical requests.
• Problem-Solving: Helpful if you encounter booking errors, missing information, or last-minute itinerary changes.

Best For: Travelers with unique needs, complicated itineraries, or special service requirements. It’s also recommended for first-time flyers who want reassurance and guidance from airline staff.

Frontier Airlines Check-In Time Guidelines

Timing is crucial when checking in with Frontier Airlines. Missing the check-in window can result in denied boarding.

• Online & Mobile Check-In: 24 hours to 60 minutes before departure.
• Domestic Flights (Airport Counter): Check-in closes 45 minutes before departure.
• International Flights (Airport Counter): Check-in closes 60 minutes before departure.
• Boarding Gate Deadline: You must be at the gate 15 minutes before departure.

Pro Tip: Always plan to arrive at the airport at least 2 hours before domestic flights and 3 hours before international flights.

Baggage Policies During Check-In

Understanding Frontier Airlines’ baggage rules during check-in can help you avoid unexpected costs.

Carry-On Bags

• Not included in the base fare for most tickets.
• Must fit within 24 x 16 x 10 inches (including handles and wheels).
• Checked and carry-on baggage fees are cheaper if purchased during online check-in.

Checked Bags

• Standard weight limit: 40 lbs (18 kg).
• Size limit: 62 linear inches (length + width + height).
• Overweight or oversized bags incur additional fees.

Personal Item

• One free personal item is allowed.
• Must fit under the seat with maximum dimensions of 18 x 14 x 8 inches.

Special Check-In Situations

Frontier Airlines recognizes that not all passengers fit into the standard check-in process. Certain travelers, such as minors, international passengers, large groups, and those requiring special assistance, must follow additional procedures to ensure safety, compliance, and a smooth journey. Below, we explain each of these cases in detail.

Unaccompanied Minors

Children between 5 and 14 years who travel alone must check in at the ticket counter. A parent or guardian completes the required paperwork at the counter to authorize the child’s trip. The guardian stays at the airport until the flight departs, while airline staff supervise the child during boarding and throughout the flight. Frontier ensures that minors receive personal care and attention every step of the way.

International Travelers

International passengers must present their passport, visa, and other entry documents at the airport counter for verification. Even if they check in online, they must confirm their documents at the counter before receiving a boarding pass. Airline staff review and validate the travel documents to meet international regulations. To avoid delays, international travelers should arrive at the airport earlier than usual because immigration and security checks often take extra time.

Group Travel

Groups of 10 or more passengers must allow extra time for check-in. Frontier staff process group baggage, verify passenger details, and coordinate seat assignments to ensure the entire group boards together. Groups that arrive early reduce stress and speed up the process. By planning ahead, large parties can check in smoothly without last-minute complications.

Special Assistance Passengers

Passengers who need special assistance—including wheelchair users, elderly travelers, or those with medical conditions—must check in at the ticket counter. Frontier staff arrange wheelchair service, priority boarding, and in-flight support based on each traveler’s needs. When passengers request assistance at least 48 hours before departure, the airline prepares the necessary accommodations in advance. By checking in at the counter, these passengers receive personalized care and a more comfortable travel experience.

Frontier Airlines Boarding Process

After check-in, understanding the boarding groups helps ensure a smoother process. Frontier Airlines uses zone-based boarding:

• Zone 1: Priority boarding (purchased priority, elite members, and certain credit card holders).
• Zones 2-4: General boarding based on seat location.
• Zone 5: Basic fare passengers with no carry-on.

Important: Boarding closes 15 minutes before departure.

How to Save Money During Check-In

Frontier Airlines operates as an ultra-low-cost carrier (ULCC), meaning extra services often come with additional fees. Here are tips to save:

1. Check-in online early to pay lower baggage fees.
2. Purchase seats in advance to avoid higher last-minute costs.
3. Travel light with only a personal item to skip baggage fees entirely.
4. Use the mobile boarding pass to avoid printing charges at the airport.

3. Can I check in at the airport without extra cost?

• For the best savings, complete check-in online or via the mobile app.

4. What happens if I miss the check-in deadline?

• If you fail to complete check-in before the cut-off times (45 minutes for domestic flights, 60 minutes for international), you may be denied boarding.
• In such cases, your ticket may be forfeited, and you could be required to purchase a new ticket for the next available flight.
• To avoid this, always start check-in as early as possible and ensure you arrive at the airport well in advance.

5. How early should I arrive at the airport?

• Frontier recommends arriving at least 2 hours before domestic flights and 3 hours before international flights.
• This provides enough time for check-in, security checks, and unexpected delays such as long lines or document verification.
• Boarding gates close 15 minutes before departure, so reaching the airport early helps avoid last-minute stress.

Mastering the Frontier Airlines check-in process ensures a smoother and more cost-efficient travel experience.
