If you're flying with Frontier Airlines, understanding how to check in is essential for a smooth travel experience. Frontier offers several check-in options, with the most popular being online check-in, mobile check-in, and airport check-in. The simple difference between these methods comes down to convenience, time savings, and added fees for services at the airport. Online and mobile check-in open 24 hours before departure and close 60 minutes prior to domestic flights and 2 hours prior to international flights. Passengers can check in through the Frontier Airlines website or mobile app, which is the fastest and most cost-effective option. With online check-in, travelers can select seats, pay for baggage, and receive a digital boarding pass — all without visiting the airport counter. This not only saves time but also helps avoid extra charges for things like printed boarding passes or last-minute seat assignments. If you have questions about the process or encounter issues during online check-in, Frontier’s customer service is available at +1-866-551-1186 for immediate assistance.
On the other hand, airport check-in — while still available — may involve longer wait times and additional fees. For instance, if you haven’t printed your boarding pass or checked in online in advance, Frontier may charge a service fee for doing this at the counter or kiosk. This makes online check-in the preferred method for most travelers. Another simple but important difference is that if you’re only traveling with carry-on baggage, online check-in allows you to skip the check-in desk altogether and proceed directly to security. However, if you have checked baggage, you’ll still need to drop your luggage off at the bag drop counter after checking in online. The bag drop typically closes 45 minutes before domestic flights and 60 minutes before international flights, so early arrival is essential.
For passengers who need special assistance, are traveling with pets, or have complicated itineraries, airport check-in may still be required. Additionally, group travelers or those with paper vouchers may not be eligible for online check-in and should arrive early to complete the process at the terminal. Always review your booking details in advance and confirm your eligibility for each method.
Seat selection is also an important aspect during the check-in process. While you can skip it and receive a random seat, Frontier charges for advance seat selection. Choosing your seat online during check-in ensures you get the spot you prefer and reduces stress on travel day. Keep in mind that failing to check in before the deadline can result in denied boarding, even if you’ve already paid for your ticket.
In summary, checking in with Frontier Airlines is simple, but choosing the right method makes a difference. Online check-in is ideal for saving time and avoiding fees, while airport check-in should be reserved for special circumstances. Completing check-in through Frontier’s app or website ensures a more convenient experience. If you’re unsure which check-in option is best for your trip or need help with your reservation, you can always contact Frontier Airlines at +1-866-551-1186. Planning ahead and knowing your check-in options ensures a hassle-free journey from start to finish.
