To change your Frontier Airlines reservation, follow these steps to make adjustments to your flight:

1. Online Through the Website

The most convenient way to change your Frontier reservation is through their official website:

  • Visit Frontier’s Website: Go to www.flyfrontier.com and navigate to the "Manage My Booking" section.
  • Enter Your Details: You'll need to provide your booking reference number and last name to retrieve your reservation.
  • Select Flight Changes: Once you've accessed your booking, choose the "Change Flight" option. You can modify your flight dates, times, or destinations depending on availability and your fare type.
  • Pay Any Fees: Depending on your fare and the timing of the change, you may need to pay a change fee and any difference in fare.
  • Confirm Changes: After selecting your new flight details and confirming payment, you’ll receive an email with your updated itinerary.

2. By Phone

If you prefer to speak to a live agent, you can contact Frontier Airlines customer service at +1 (888) 742-3067. Follow the automated menu to get directed to a live person who can help you change your reservation. Be prepared with your booking details for quicker assistance.

3. Mobile App

You can also use the Frontier Airlines mobile app to manage and change your reservation, similar to the website process.

Note:

Keep in mind that change fees may apply, and there could be a difference in fare depending on availability and your ticket type (e.g., standard or discount).
