The Best Way to Check-In: The Frontier Mobile App

Regarded as one of the most convenient and cost-effective ways to check in for your Frontier flight. The airline strongly recommends passengers to choose this option heavily, and for all good reasons- it saves them money, and saves their passengers from spending unnecessary money. Now let’s look at some key areas of this option:

  • When to check-in: Log in to their mobile app where you can check-in 24 hours before your flight’s departure which is up until 60 minutes before the takeoff. 
  • How the process works: Start by downloading the free Frontier Airlines app for iOS or Android. As soon as the check-in window opens, enter your confirmation code and last name. Confirm your flight details, add any last-minute bags at a much lower price than at the airport, and receive your digital boarding pass. 
  • Tips to avoid fees: Using the mobile application and a digital boarding pass is completely free. This is the best way to avoid the Airport Agent Assistance fee.

Online Check-In on Frontier Airlines Website: Step-by-Step Guide

Well, if you prefer a bigger screen, then the official website is your next best option. This process is very similar to the mobile app. 

  • When to check-in: You can typically check-in online starting from 24 hours before your flight and up to 40 minutes before departure. This saves you from skipping the long lines at the airport check-in. 
  • How it works: Visit the FlyFrontier website, look for a check-in or online check-in button or link. Enter your details, provide your confirmation code, first and last name to retrieve your booking. Pay for any extra bags, choose your seats (if you’ve not selected or want to change your seat), or other add-ons. After confirming all these details, you can print your boarding pass at home. 
  • Fee-avoidance tip: While the website is free, to avoid fees, arrive with only one personal item that fits under your seat, book directly through the airline’s website, and consider buying a “Discount Den” membership for potential savings on seats and bags. Similarly, always carry the printed boarding pass, unless you want to pay for a reprint at the airport.

Airport Check-In for Frontier Airlines: Fees, Kiosks, and Counters

This should be your absolute last resort, as checking in at the airport is most likely to incur you with additional fees. If you’re still waiting to check-in at the airport, you have two options: a self-service kiosk or the ticket counter. 

  • Self-service kiosks- Available in almost all airports which allows you to check in and print your boarding pass. You can also pay for your bags at the kiosk. But keep in mind that it will be more expensive than paying for them in advance through online platforms and their official website. 
  • Ticket counter- This is the most expensive option. Using an agent at the ticket counter for check-in or printing will lead you to pay an additional fee of up to $25 per passenger. 

No matter how you choose to check-in, be very careful and mindful of the deadlines. For both domestic and international flights, you must check-in and have all your bags dropped off at least 60 minutes before your scheduled departure time. Arriving late and missing the deadline will result in Frontier Airlines cancelling your reservation under a “No Show Cancellation” & you’ll lose the value of your ticket. 

Conclusion

Checking in for your Frontier flight doesn’t have to be an expensive experience. By planning in advance and using the mobile app or website appropriately can help easily avoid unnecessary fees and ensure a smooth start to your travel journey.
