A “Spirit AI Miramar FL” charge on your bank or credit card statement is a Spirit Airlines transaction, tagged with the city where the airline’s headquarters processes payments. It could be a ticket, a bag fee, a seat selection, an in-flight purchase, or an annual membership renewal. Because Spirit charges for almost everything separately, one trip can produce several of these entries on the same statement.
What the Descriptor Actually Means
“Spirit AI” is shorthand for Spirit Airlines on merchant billing systems. “Miramar FL” appears because Spirit has been headquartered at the Miramar Park of Commerce in Miramar, Florida, since 1999, and every payment routes through that location. Where you booked, where you flew, and whether you have ever visited Florida make no difference. Every Spirit charge carries the same city tag.
If you booked through a third-party site such as Expedia or Orbitz, the descriptor can go either way. Sometimes the charge posts under the travel agency’s name, and sometimes it posts under Spirit directly when the airline processed that portion of the payment itself.
What the Charge Is Likely For
Spirit’s base fare covers a seat and one personal item. Almost everything else is priced and billed separately, which is why a single trip often creates multiple line items. Common sources of a Spirit charge include:
- Carry-on bags, with fees that start lower at booking and climb the longer you wait, peaking at the gate.
- Checked bags, priced individually for the first, second, and additional bags, plus overweight and oversized surcharges.
- Seat selection, which varies by route and seat location.
- The Big Front Seat, Spirit’s wider front-of-plane option, often running roughly $25 to $75 or more depending on route and demand.
- Onboard food and drinks, none of which are complimentary. Hot beverages start at $3.99, cold drinks at $4.49, and alcoholic drinks at $10.99, with snack and combo bundles running from about $7 to $39.1Spirit Airlines. Inflight Menu
- Flight changes on a “Go” fare, with fees that rise as departure approaches; changes 60 or more days out currently have no fee.
- Saver$ Club membership, which costs $69.95 per year and renews automatically.2Spirit Airlines. Savers Club Terms and Conditions
A round-trip with a checked bag, a seat selection, and a couple of onboard purchases can easily post as four or five separate “Spirit AI Miramar FL” entries. That alone accounts for a lot of the surprise these charges cause.
Match the Charge to Your Own Records First
Before calling anyone, search your email for messages from Spirit Airlines. Booking confirmations include a six-character confirmation code, the flight date, and a price breakdown. If the email total matches the statement amount, you’re done.
If the numbers don’t line up, remember that ancillary fees post separately. A $127 charge might be the base fare while a $41 charge the same day is a carry-on added at check-in. Dates can also drift by a day or two after the actual purchase, which is common for in-flight buys. And check whether anyone else authorized on your card, such as a family member or travel companion, booked a Spirit flight. Their itinerary produces the same descriptor on your statement.
Saver$ Club Auto-Renewal
The single most common surprise Spirit charge is the $69.95 annual Saver$ Club renewal. Signing up authorizes automatic annual billing, and Spirit charges the card on file at the renewal date without a reminder email. If the original card has expired, the terms authorize Spirit to try another payment method on your account.2Spirit Airlines. Savers Club Terms and Conditions
To cancel, log into your Spirit account and use the unsubscribe option in your Saver$ Club profile. Online cancellations take effect within 24 hours. A mailed written cancellation also works but takes four to six weeks to process, so if renewal is close, cancel online.2Spirit Airlines. Savers Club Terms and Conditions
Contacting Spirit Before Your Bank

When Spirit Owes You a Refund
Federal rules protect you when Spirit cancels your flight or makes a significant schedule change. Under DOT regulations finalized in 2024, airlines must issue automatic cash refunds when a flight is cancelled and you decline rebooking or travel credits. The same applies when the airline delays your arrival by three hours or more on a domestic flight, or six hours or more on an international one.4US Department of Transportation. Refunds
Refunds go back to your original form of payment within seven business days for credit card purchases and within 20 calendar days for other payment methods. The refund covers the full ticket price, including government taxes and airline fees. Ancillary services you paid for but did not receive, such as checked bags, Wi-Fi, or seat selection, must be refunded separately.5Federal Register. Refunds and Other Consumer Protections
These rules do not apply when you simply chose not to fly on a non-refundable ticket, or when you took the flight and were disappointed with the service. They apply only when the airline cancels or significantly changes the itinerary and you decline the alternative.4US Department of Transportation. Refunds
Disputing an Unauthorized Charge
If neither your records nor Spirit can account for the charge, treat it as unauthorized. The Fair Credit Billing Act lets you dispute billing errors on credit card statements, but there is a hard deadline. You must send a written dispute within 60 days of the date on the statement that first showed the charge.6Federal Trade Commission. Fair Credit Billing Act Miss that window and you lose the statute’s protections.
The written notice must go to the billing inquiry address your card issuer designates for disputes, which is different from the payment address. Include your name, account number, the amount you believe is wrong, and why you think it’s an error.7Office of the Law Revision Counsel. 15 USC 1666 Correction of Billing Errors Certified mail with a return receipt gives you proof it arrived on time.
Most banks also let you open a dispute through their app or by calling the number on the back of your card, which is faster if you want a provisional credit while the investigation runs. Once notified, the issuer must acknowledge the dispute within 30 days and resolve it within two billing cycles. During the investigation, the issuer cannot try to collect the disputed amount or report it as delinquent.7Office of the Law Revision Counsel. 15 USC 1666 Correction of Billing Errors
If the charge is outright fraud rather than a billing mix-up, ask the issuer to flag the card and send a replacement. A single unfamiliar airline charge sometimes points to a broader compromise of the card number, and catching it early prevents the next one.
