About Frontier Airlines

Frontier Airlines is an ultra-low-cost carrier headquartered in Denver, Colorado, operating a network of routes across the United States, Mexico, the Caribbean, and select other destinations. The airline focuses on no-frills, low base fares, with additional fees for options like seat selection, carry-on and checked baggage, and priority boarding. Customers typically book flights directly through Frontier’s website or mobile app, or via online travel agencies.

A charge labeled something like “FRONTIER AI WG22GZ” on your card statement is most likely related to a flight purchase, itinerary change, baggage fee, seat assignment, or other ancillary service purchased from Frontier Airlines. The trailing code (such as “WG22GZ”) is often an internal reference, booking code, or ticket/record locator associated with your reservation. Charges may appear when you initially book, when you modify a trip, add bags or seats, or purchase options like FLEX or bundled fare packages. In some cases, small temporary authorization holds may appear when a card is added or updated during booking.

If you have questions about this charge, start by checking your email for a confirmation from Frontier Airlines for flights, ancillary purchases, or changes around the date of the transaction. You can also log into your Frontier account or use the “My Trip/Check-In” section on their website with your last name and confirmation code to view receipts and trip details. If the charge still looks unfamiliar or appears incorrect, contact Frontier’s customer support through their website or app, or reach out via their customer service phone line. For disputed or fraudulent charges, notify both Frontier and your card issuer promptly so they can investigate and resolve the issue.

Frequently Asked Questions

What does the code like “WG22GZ” after FRONTIER AI mean on my statement?

The code following “FRONTIER AI” (such as “WG22GZ”) is typically an internal booking or ticket reference associated with your Frontier Airlines reservation. You can match it against your flight confirmation email or your trip details under “My Trip/Check-In” on flyfrontier.com.

Why do I see multiple charges from Frontier Airlines for one trip?

With Frontier’s ultra-low-cost model, base fares and extras such as bags, seat selection, and trip options may be billed as separate line items. You might see one charge for the ticket and additional charges for baggage, seat assignments, or changes made after the original booking date.

How can I get a receipt or invoice for my Frontier Airlines charge?

You can retrieve receipts by visiting flyfrontier.com and using the “My Trip/Check-In” feature with your last name and confirmation code. From there, you can view and print receipts for your ticket, baggage, and any add-on purchases tied to that reservation.

How do I modify or cancel a flight that corresponds to this Frontier Airlines charge?

Go to flyfrontier.com or the Frontier app, select “My Trip/Check-In,” and enter your last name and confirmation code. From there you can change or cancel flights, subject to Frontier’s fare rules and any applicable change or cancellation fees. Refund eligibility depends on the fare type and timing.

Can I get a refund for a Frontier Airlines charge I no longer recognize or need?

Refunds are limited and depend on the fare type, whether you purchased a refundable option, and when you cancel relative to departure. If you don’t recognize the charge, contact Frontier customer support with your card details, charge date, and any confirmation numbers so they can locate the transaction and advise on refund or credit options.

Why do I see a small or temporary Frontier Airlines charge that later disappeared?

Frontier may place a temporary authorization hold on your card when you enter payment details or attempt a booking. If the booking fails or is not completed, the hold typically expires and drops off your statement within a few business days, depending on your bank.

How can I contact Frontier Airlines about a billing issue?

Visit flyfrontier.com and go to the Help or Contact section for current support options, which may include virtual chat, online forms, and phone support. Having your confirmation code, flight details, and the exact charge amount/date ready will help them quickly locate your transaction.

Why is my Frontier Airlines charge higher than the advertised fare?

Frontier advertises low base fares and then allows customers to add paid options, such as carry-on and checked bags, specific seats, and other services. The final amount charged reflects the base ticket price plus any extras selected during booking or added later, as well as applicable taxes and fees.
