Need to change a Frontier flight date? As an ultra-low-cost carrier, Frontier charges a change fee on most fares — but it's tiered, meaning it shrinks the earlier you act and can drop close to $0 if you change far enough ahead. On top of the fee you pay any fare difference. This guide shows you exactly how to change a Frontier flight date for the lowest possible cost.
Want the cheapest new date found for you? Call +1 (855) 302-0422 (24/7) and our agents will rebook your Frontier flight at the lowest available cost.

What it costs to change a Frontier flight date
Two charges can apply: the tiered change fee (based on how far ahead you change) and the fare difference if the new flight costs more. The earlier you change, the smaller the fee. (Exact amounts vary by fare type and change often — call to confirm.)
| When you change (before departure) | Change fee — typical pattern |
|---|---|
| Far in advance | Lowest tier — can approach $0 |
| A week or more out | Moderate fee |
| Within a few days | Higher fee |
| Close to departure | Highest fee |
Ways to lower or avoid the change fee
- Change early. The single biggest factor — the fee drops the further out you are.
- Use the 24-hour rule. Booked 7+ days ahead? Cancel within 24 hours for a full refund and rebook your real date free. See the 24-hour flight cancellation rule.
- Buy a flexible bundle (like "the Works") at booking if plans may move — it can waive change fees.
- Pick a cheaper new date — mid-week and off-peak flights keep the fare difference small.
How to change a Frontier flight date: step by step
- Have your confirmation code and passenger name ready.
- Pick your new date — flexible by a day or two means cheaper options.
- Check both costs — the change fee and the fare difference.
- Confirm the change and save your new itinerary.
- Note any credit if the new flight is cheaper than the original.
Common mistakes when changing a Frontier flight
- Waiting too long — letting the change fee climb into a higher tier when an early change would have been near $0.
- Picking a peak new date — a Friday or holiday return can make the fare difference dwarf the fee itself.
- Assuming "no fee" airlines apply — Frontier is a ULCC, so unlike some legacy carriers it does charge to change unless you bought flexibility.
- No-showing instead of changing — that forfeits the ticket entirely. Always change or cancel before departure.
Change vs. cancel and rebook
Because Frontier base fares are low, cancelling and rebooking is occasionally cheaper than a change fee plus fare difference — especially inside the 24-hour window. We'll compare both for you. For the cancel route, see the Frontier Airlines cancellation and refund policy.
