A COT*FLT charge on your credit card is a flight purchase made through Capital One Travel, Capital One’s online booking portal for flights, hotels, and car rentals. The abbreviation breaks down as “COT” (Capital One Travel) and “FLT” (Flight). It most commonly appears on Capital One credit card statements, though it can show up on any card used through the portal.
This guide draws on publicly available Capital One documentation, the Fair Credit Billing Act (FCBA), and real consumer dispute processes to help you identify, verify, and — if necessary — dispute a COTFLT charge quickly. Whether you see a cotflt charge, a cot*flt credit card charge, or a cot flt biz entry, the steps below will walk you through exactly what to do.
What Is the COT*FLT Charge on Your Credit Card?
Many people believe a COTFLT charge is a foreign transaction fee or some kind of processing surcharge. That’s incorrect. The COT*FLT descriptor is simply how Capital One Travel labels flight bookings on your billing statement.
Capital One Travel is an online travel portal available to Capital One cardholders. It lets users book flights, hotels, and rental cars — often earning bonus rewards. When you (or an authorized user on your account) book a flight through this portal, the transaction posts as:
- COT*FLT — for flight purchases
- COT*HTL — for hotel bookings
- COT*FLT BIZ or COT*FLTBIZ — for flights booked through Capital One Travel’s business portal
The charge amount reflects the actual cost of the airline ticket, including taxes and booking fees. It is not a hidden surcharge or penalty.
COT*FLT Variations You Might See on Your Statement
Credit card processors often truncate or format merchant names differently. Here are the most common variations of the same Capital One Travel flight charge — all refer to the same type of transaction:
| Statement Descriptor | What It Means |
|---|---|
| COT*FLT | Capital One Travel – Flight booking |
| COTFLT | Same charge, no asterisk displayed |
| COT FLT | Same charge, space instead of asterisk |
| COT*FLT BIZ | Flight booked via Capital One Business Travel |
| COT*FLTBIZ | Business flight booking (compressed format) |
| COT*FLTBIZBOSTON MA | Business flight booking processed in Boston, MA |
| COT*FLT BOSTON MA | Flight booking processed through Boston office |
| COT*FLT 627-2363070 MA | Flight booking with Capital One phone number |
| COT*FLT 844-422-6922 DE | Flight booking with customer service number |
| COT*HTL BIZ | Capital One Travel – Hotel booking (business) |
Insider tip: The phone numbers included in some descriptors (like 844-422-6922) are Capital One Travel’s actual customer service lines. You can call those numbers directly to get details about the specific transaction.
Why Did a COTFLT Charge Appear on Your Statement?
Before assuming fraud, consider the most common — and often innocent — explanations for a COT*FLT charge:
1. You Booked a Flight Through Capital One Travel
This is the most likely scenario. If you hold a Capital One Venture, Venture X, Savor, or Spark card, you may have booked a flight through the Capital One Travel portal. The purchase shows up as COT*FLT rather than the airline name, which catches many people off guard.
2. An Authorized User Made the Purchase
If someone else is an authorized user on your account — a spouse, partner, or family member — they may have booked a flight without telling you. Check with all authorized users before escalating to a dispute.
3. A Subscription or Travel Membership Fee
Some Capital One cardholders have travel memberships or premium card benefits that involve periodic charges through the travel portal. These can also appear with the COT*FLT descriptor.
4. Unauthorized or Fraudulent Activity
If none of the above apply, the charge may be fraudulent. Credit card fraud remains a significant concern: the Federal Trade Commission reported that consumers lost over $10 billion to fraud in 2023, with credit card fraud among the most common types. Act quickly if you suspect unauthorized use of your card.
COT*HTL: The Hotel Version of the Same Charge
If you see COT*HTL or COT*HTLBIZ on your statement, this is the hotel equivalent of the COT*FLT charge. It means someone booked a hotel through Capital One Travel. The same verification and dispute steps apply.
The key difference: COT*HTL charges sometimes appear as pre-authorizations before the hotel stay and then post as a final charge after checkout. This can create temporary “double charges” that resolve within 3–5 business days. Similar to how Partners on Booking BV credit card charges work with hotel booking platforms, the pre-authorization hold drops off once the final amount is confirmed.
COT*FLT Boston MA — What the Location Means
Many statement descriptors include “Boston MA” — such as COT*FLT BOSTON MA, COT*FLTBOSTONMA, or COT*FLT BIZ BOSTON MA. This does not mean the flight departs from Boston.
Boston, Massachusetts is where Capital One Travel’s payment processing operations are located. Regardless of whether you booked a flight from Los Angeles to Miami or New York to London, the charge may show a Boston, MA location because that’s where the transaction was processed.
What most guides don’t mention: The “DE” that appears in some descriptors (e.g., COT*FLT 844-422-6922 DE) refers to Delaware — where Capital One is incorporated as a financial institution. It doesn’t mean the transaction involved the state of Delaware or an international charge.
How to Verify Whether the Charge Is Legitimate
Before filing a dispute, take these steps to confirm whether the COT*FLT charge is valid:
- Log in to Capital One Travel: Visit the Capital One Travel portal or your Capital One mobile app. Check your booking history for any flights matching the charge date and amount.
- Check your email: Search your inbox for booking confirmations from Capital One Travel. Look for subject lines containing “itinerary” or “booking confirmation.”
- Ask authorized users: Contact anyone with access to your credit card account. A family member may have booked a flight without mentioning it.
- Match the amount: Compare the charge amount against airline ticket prices you may have browsed recently. Sometimes a booking you thought you abandoned actually went through.
- Call the number on the descriptor: If the charge includes a phone number (e.g., 844-422-6922 or 627-236-3070), call it directly. Capital One Travel’s support team can look up the transaction details.
If you’ve exhausted these steps and still don’t recognize the charge, it’s time to dispute it.
How to Dispute an Unauthorized COT*FLT Charge
Disputing an unauthorized cotflt charge is straightforward. Follow this step-by-step process:
Step 1: Contact Capital One Travel Directly
Call Capital One Travel at 844-422-6922. Ask them to look up the transaction by your card number and the charge date. In many cases, they can identify the booking and resolve the issue without a formal dispute. If there’s a mistaken charge, they may process a refund directly.
Step 2: Report the Charge to Your Card Issuer
If Capital One Travel can’t resolve it — or if the charge appears on a non-Capital One card — contact your credit card issuer immediately. You can:
- ✓ Call the number on the back of your credit card
- ✓ Use your issuer’s mobile app to flag the transaction
- ✓ Submit a dispute form through your online banking portal
Step 3: File a Written Dispute (Recommended)
Under the Fair Credit Billing Act, you have the right to submit a written dispute within 60 days of the statement date. Send your dispute letter to your issuer’s billing inquiries address (not the payment address). Include:
- ✓ Your name and account number
- ✓ The date and amount of the disputed charge
- ✓ A clear explanation of why you believe the charge is incorrect
Step 4: Monitor Your Account
Your issuer must acknowledge your dispute within 30 days and resolve it within two billing cycles (but no more than 90 days). During the investigation, you don’t need to pay the disputed amount, and no interest accrues on it.
Step 5: Request a Replacement Card
If the charge turns out to be fraudulent, request a new card with a different number immediately. This prevents the fraudster from making additional purchases. Most issuers will expedite a replacement card at no cost.
If you’ve dealt with other mysterious charges before — such as an Achma Visb charge on your credit card — you know the dispute process follows the same general framework regardless of the merchant.
Your Legal Rights and Protections
Federal law provides strong protections for credit card holders dealing with unauthorized charges. Here’s what you need to know:
Fair Credit Billing Act (FCBA)
The FCBA (15 U.S.C. § 1666) limits your liability for unauthorized credit card charges to a maximum of $50. In practice, all major card issuers — including Capital One, Chase, American Express, and Discover — offer $0 liability policies for unauthorized transactions. This means you won’t owe anything for fraudulent charges.
Key FCBA protections include:
- ✓ 60-day window to dispute billing errors in writing
- ✓ Card issuer must acknowledge your dispute within 30 days
- ✓ Resolution required within two billing cycles (max 90 days)
- ✓ No interest charged on disputed amounts during investigation
Electronic Fund Transfer Act (EFTA)
If the COT*FLT charge appeared on a debit card rather than a credit card, the EFTA applies instead. Your liability depends on how quickly you report the issue:
| Reporting Timeframe | Maximum Liability |
|---|---|
| Within 2 business days | $50 |
| Within 60 days | $500 |
| After 60 days | Unlimited |
This is why speed matters. Report suspicious charges immediately — especially on debit cards, where your liability increases with time. Similar urgency applies when you spot any unfamiliar charge on a debit card.
Preventing Unauthorized Charges in the Future
Once you’ve resolved a COT*FLT dispute, take these steps to protect yourself going forward:
Enable Real-Time Transaction Alerts
Most card issuers offer free push notifications for every purchase. Turn these on through your bank’s mobile app. You’ll know about any charge within seconds of it posting — giving you the fastest possible response time.
Review Statements Monthly
The Consumer Financial Protection Bureau (CFPB) recommends reviewing your credit card statement every billing cycle. Don’t just glance at the total. Scan each line item for unfamiliar merchant names, small “test charges” (fraudsters often run $1–$5 charges before making larger purchases), and duplicate transactions.
Use Strong Authentication
- ✓ Enable two-factor authentication on your Capital One account
- ✓ Use unique passwords for every financial account
- ✓ Lock your card through your issuer’s app when not in use
Be Cautious With Authorized Users
If you add authorized users to your account, establish clear communication about purchases. Many “mysterious” COT*FLT charges turn out to be legitimate bookings by a family member who simply forgot to mention it.
How Virtual Credit Cards Protect You From Fraud
One of the most effective ways to prevent unauthorized charges — including fraudulent COT*FLT transactions — is using virtual credit cards for online purchases.
A virtual credit card generates a unique, temporary card number for each transaction. Even if a fraudster intercepts the number, it’s useless after the purchase completes. Key benefits include:
- ✓ Single-use numbers that expire after one transaction
- ✓ Custom spending limits you set per card
- ✓ Instant creation — no waiting for a physical card
- ✓ Full control to freeze or delete cards at any time
Services like Cardvcc let you create virtual credit cards instantly. This adds a powerful layer of protection when booking travel, subscribing to services, or shopping at unfamiliar merchants online.
Virtual cards are especially useful for managing recurring travel charges. If you regularly book through platforms like Capital One Travel, you can assign a dedicated virtual card to each booking — making it easy to track exactly which charge belongs to which trip.

Frequently Asked Questions
What is COT*FLT?
COT*FLT stands for “Capital One Travel – Flight.” It is a billing descriptor that appears on your credit card statement when a flight is booked through the Capital One Travel portal. The charge reflects the cost of the airline ticket, including taxes and fees. It is not a hidden fee or surcharge — it represents an actual flight purchase made through Capital One’s travel booking platform.
Why does my COT*FLT charge say Boston MA?
The “Boston MA” in a COT*FLT descriptor refers to where Capital One Travel processes payments — not your flight destination or departure city. Capital One Travel’s payment processing is based in Boston, Massachusetts. Similarly, “DE” in some descriptors refers to Delaware, where Capital One is incorporated. The location has nothing to do with your actual travel itinerary.
What is the difference between COT*FLT and COT*FLT BIZ?
COT*FLT appears for personal flight bookings through Capital One Travel, while COT*FLT BIZ (or COT*FLTBIZ) indicates a flight booked through Capital One’s business travel portal. Business cardholders using Spark or other Capital One business cards will typically see the “BIZ” designation. Both represent legitimate flight purchases — the only difference is the booking portal used.
How do I get a refund for a COT*FLT charge?
If you booked the flight yourself and want a refund, contact Capital One Travel at 844-422-6922 to check your booking’s cancellation policy. Refund eligibility depends on the airline and fare type. If the charge is unauthorized, contact your card issuer to file a dispute under the Fair Credit Billing Act. You have 60 days from the statement date to submit a written dispute, and you won’t owe interest on the disputed amount during the investigation.
Can a COT*FLT charge appear on a non-Capital One credit card?
Yes. While Capital One Travel is primarily designed for Capital One cardholders, it’s technically possible for the COT*FLT descriptor to appear if a payment was processed through Capital One’s travel system. However, this is rare. If you see COT*FLT on a Chase, Amex, or other issuer’s statement and didn’t use Capital One Travel, treat it as a suspicious charge and contact your card issuer immediately to investigate.
What does COT*HTL mean on my credit card?
COT*HTL stands for “Capital One Travel – Hotel.” It appears when a hotel is booked through the Capital One Travel portal. The same verification steps apply: check your Capital One Travel booking history, ask authorized users, and contact Capital One Travel support if you don’t recognize the charge. The COT*HTLBIZ variant indicates a hotel booked through the business travel portal.
