you can change your flight date on a Frontier ticket support.accountingseed.com

Yes, you can change your flight date on a Frontier ticket, but it may come with a fee based on how early you make the change. For modifications made 60 days or more before departure, there is no fee. However, changes made 59-7 days before your flight incur a $49 fee, and those made within 6 days cost $79. Any fare differences must also be covered. Changes can be managed through Frontier’s “My Trips” portal online, their mobile app, or by reaching customer service. Same-day flight changes are also possible for an additional fee, subject to availability.
