What a travel certificate is and how it differs from flight credit

A travel certificate is a document issued by an airline that lets you book a flight without paying cash at the time of purchase. A flight credit, by contrast, is money the airline holds in your account — usually issued when you cancel a ticket or don't use a voucher before its expiration date. The two are not the same thing, and converting one to the other depends on which airline you booked with and what their specific rules allow.

Most airlines do not automatically convert unused flight credit into a travel certificate. You have to request the conversion yourself, and not every airline offers this option. Some airlines treat flight credit and travel certificates as separate products with different rules about how long you can use them, who can use them, and whether they can be refunded if unused.

The reason this matters: a travel certificate often has a longer expiration window than flight credit, and in some cases a certificate can be transferred to another person or used by a family member, while credit cannot. Before you convert, check your airline's rules about what you gain and what you lose by making the switch.

Key Takeaways

  • Most airlines require you to contact them directly to convert flight credit into a travel certificate — the conversion does not happen on its own.
  • Travel certificates usually last longer than flight credit and may be transferable to another person, depending on the airline.
  • Some airlines charge a fee to convert credit to a certificate, while others do it at no cost.
  • You will need your booking confirmation number and the original ticket number to request a conversion.
  • Not all airlines offer this conversion option, so check your airline's policy before you assume it is available.

How to find your airline's conversion policy

Start by visiting your airline's official website and searching for "flight credit" or "travel certificate" in their help or FAQ section. Most major carriers — United, American, Delta, Southwest, and others — post their policies in writing, though the language and location vary widely. Look for a page titled "Refunds and Credits" or "Booking Changes and Cancellations."

If you cannot find the policy online, call the airline's customer service line. Have your booking confirmation number ready. Ask specifically: "Can I convert my flight credit into a travel certificate?" and "If yes, is there a fee, and how long will the certificate last?" Write down the name of the agent and the date of the call in case you need to reference it later.

Some airlines only allow conversion within a certain time window — for example, within 90 days of the original booking or before the credit expires. Others allow conversion at any time. Knowing this important date matters because it affects when you need to act.

The step-by-step process for requesting a conversion

Once you have confirmed your airline offers conversion, you have two main routes: online or by phone. The online route is faster if your airline has a self-service option. Log into your account on the airline's website, find your booking, and look for an option to "convert to certificate" or "request a certificate." Not all airlines offer this; if you do not see it, move to the phone route.

To convert by phone, call the airline's main customer service number. Tell the agent you want to convert your flight credit to a travel certificate. Provide your booking confirmation number and the original ticket number (both are on your confirmation email). The agent will confirm the credit amount, explain any fees, and tell you how long the certificate will last.

Ask the agent to email you a confirmation of the conversion, including the certificate number, the amount, and the expiration date. Do not hang up until you have this in writing. If the agent says they will mail it, ask for an email instead — mail is slower and easier to lose.

Fees and what they cover

Some airlines charge a conversion fee, typically between $25 and $75, depending on the carrier and the credit amount. Others do not charge anything. The fee is usually deducted from your credit balance, so if you have a $300 credit and the fee is $50, your certificate will be worth $250.

Before you convert, ask the agent whether a fee applies and what it covers. Some airlines charge a flat fee; others charge a percentage of the credit amount. A few airlines waive the fee if you convert within a certain time frame after the original cancellation.

If the fee seems high relative to your credit amount, consider whether you would rather keep the credit and use it as-is, even if it expires sooner. A $50 fee on a $100 credit is a significant loss.

Expiration dates and transferability rules

Travel certificates typically last longer than flight credit. Flight credit often expires within one to two years, while a travel certificate may be valid for three to five years, depending on the airline. This is one of the main reasons to convert — you get more time to use the money.

Transferability varies by airline. Some airlines allow you to give your certificate to a family member or friend; others do not. If transferability matters to you — for example, if you want to give the certificate as a gift — ask the agent before you convert. Some airlines only allow transfer if the certificate was issued as a result of a schedule change or cancellation by the airline, not a passenger-initiated cancellation.

Write down the expiration date and any transfer restrictions. Set a phone reminder for two months before expiration so you do not lose the value by forgetting to book.

What happens if you do not use the certificate before it expires

If your travel certificate expires unused, the airline keeps the money. Most airlines do not refund expired certificates, and they do not extend the expiration date as a courtesy. Once the date passes, the certificate has no value.

Some airlines have made exceptions during specific circumstances — for example, during the COVID-19 pandemic, many carriers extended certificate expiration dates. These are rare and typically announced publicly. Do not count on an extension.

If you are concerned you will not use the certificate in time, book a flight now, even if you plan to take it months from now. You can usually change the dates later without a fee if you have a certificate, whereas you cannot recover the money after expiration.

Alternatives if your airline does not offer conversion

If your airline does not convert flight credit to travel certificates, you have a few other options. The most straightforward is to use the credit to book a flight before it expires. You can book any route the airline operates, and you can change the dates later in most cases without paying a change fee (though you may owe the difference if you book a more expensive flight).

Another option is to check whether your airline allows you to transfer the credit to another person. Some carriers let you give your credit to a family member or friend, who can then use it to book. This is not the same as a certificate, but it extends the usefulness of the money.

If neither of those options works and your credit is about to expire, consider booking a flight you might actually take — even a short regional flight — rather than losing the value entirely. A $200 credit used for a $200 flight is better than a $200 credit that expires.

Frequently Asked Questions

Can I convert flight credit to a certificate if the original ticket was non-refundable?

Yes. Whether your original ticket was refundable or non-refundable does not affect whether you can convert credit to a certificate. The conversion rules are separate from the original ticket terms. However, check your airline's policy, because some carriers have different rules for credit issued from refundable versus non-refundable tickets.

What if I have multiple flight credits from different bookings?

You will need to convert each credit separately. Most airlines do not combine credits from different bookings into a single certificate. Contact the airline for each booking confirmation number and request a conversion for each one. You will receive separate certificates with separate expiration dates.

Can I use a travel certificate to book a flight for someone else?

It depends on the airline. Some certificates are non-transferable and can only be used by the person whose name is on the original booking. Others allow the certificate holder to book a flight for any passenger. Ask the agent during the conversion process whether the certificate is transferable, and get the answer in writing.

What if the airline goes out of business before I use my certificate?

If an airline ceases operations, your certificate typically becomes worthless unless another airline acquires the company and honors the certificates. This is rare, but it is a real risk. If you are concerned about an airline's stability, use your certificate sooner rather than later.

Do I have to pay taxes on a travel certificate?

No. A travel certificate is not considered income, so you do not owe taxes on it. It is a credit toward a future purchase, not a payment or gift. When you use the certificate to book a flight, you pay taxes on the flight itself, just as you would with any other booking.
