A travel voucher is a document or electronic credit issued by an airline or travel provider that entitles the holder to apply a specified value toward a future booking. Vouchers arise from flight disruptions, voluntary seat surrenders, non-refundable ticket changes, and promotional offers, each with its own expiration and usage conditions.
A travel voucher is a document or electronic credit that entitles the holder to apply a specified value toward a future booking. Vouchers arise from flight disruptions, voluntary seat surrenders, non-refundable ticket changes, and promotional offers. For travelers and finance teams alike, understanding the types and expiration rules prevents value from going unclaimed.
Travel vouchers fall into three main forms: compensation vouchers (for disrupted travel), unused ticket credits (for non-refundable fare changes), and denied boarding vouchers (offered when passengers voluntarily give up seats on overbooked flights).
Under current U.S. DOT rules, travel credits offered in lieu of a refund for a canceled or significantly changed flight must be valid for at least five years from the date of issuance and must be transferable [1].
A 2025 GBTA study found that 54% of corporate travel managers struggle to manage unused tickets within their online booking tools [2].
Navan surfaces available unused ticket credits at the point of rebooking, so travelers can apply existing value without manually tracking credits across carrier portals.
Finance teams should treat outstanding travel vouchers as active travel budget assets — unclaimed credits expire and represent real cash value lost.
What is a Travel Voucher?
A travel voucher is a document or electronic credit issued by an airline, hotel, or travel agency that entitles the holder to apply a specified value toward a future travel purchase. Unlike a cash refund, a voucher keeps the value within the provider's system and comes with conditions: an expiration date, restrictions on which routes or properties it covers, and sometimes a single-use or non-transferable limitation.
Vouchers enter the picture in a few common ways: a flight is canceled and the airline offers credits instead of a cash return, a traveler voluntarily gives up a seat on an overbooked flight in exchange for compensation, a non-refundable booking changes and the unused fare value is preserved as a credit, or a provider issues credits as a promotional benefit.
The defining characteristic of a travel voucher is that the value stays tethered to the issuer. It can't be converted to cash or applied to a different provider's services, which makes understanding the terms at issuance, not at redemption, the key discipline for making good use of them.
Types of Travel Vouchers
Travel vouchers aren't a single product. They differ by origin, value structure, and redemption conditions.
Compensation vouchers: Issued when an airline disrupts a passenger's journey through a cancellation, significant delay, or involuntary denied boarding. This is the most regulated category. Under U.S. Department of Transportation rules, travel credits offered instead of cash refunds for canceled or significantly changed flights must be valid for at least five years from the date of issuance and must be transferable to another traveler [1].
Unused ticket credits: When a traveler holding a non-refundable ticket can't fly and changes or cancels the booking, the carrier typically preserves the residual ticket value as a credit. These credits are tied to the original traveler's name and a specific carrier, and they expire — often within 12 months of the original ticket purchase or issue date. For corporate travel programs, unused ticket credits represent a meaningful pool of potential savings if systematically tracked and reused.
Denied boarding vouchers: When a flight is overbooked and a carrier asks passengers to voluntarily give up their seats, the compensation — a flight credit plus sometimes a meal voucher or hotel accommodation — constitutes a voucher. Carriers routinely offer flight credit at a premium over the cash equivalent. If the traveler regularly flies that carrier, the premium is easily captured on the next booking.
Promotional vouchers: Issued as marketing incentives: welcome offers, loyalty program promotions, or partnership agreements. These typically carry the most restrictions: blackout dates, minimum spend thresholds, and single-property or single-route limitations.
How Do Travel Vouchers Work in Corporate Programs?
For individual travelers, a voucher might mean a discount on a future personal booking. For corporate travel programs, unused ticket credits represent a budget consideration that's frequently mismanaged.
The challenge is systemic. According to the Global Business Travel Association's 2025 "Perfect Business Trip" report — based on a March 2025 survey of 166 U.S. and Canadian corporate travel managers — 54% of respondents struggle to manage unused tickets within their online booking tools. Only 17% can redeem unused ticket credits on a self-service basis [2]. When credits aren't tracked, they expire without being applied: a direct and avoidable cost to the organization.
The best-managed programs treat outstanding vouchers as line items. Finance teams who include active travel credits in their T&E budget reviews can capture value from rebooked trips that would otherwise require fresh spend. In practice, this means integrating the voucher balance into the booking workflow so that when a traveler searches for a replacement flight, available credits appear at the point of purchase rather than buried in a separate carrier portal.
Navan integrates outstanding unused ticket credits into the booking workflow, surfacing them when travelers search for replacement trips. This connects directly to travel policy compliance goals: a voucher applied correctly is a flight purchased within budget rather than a new expenditure.
Best Practices for Managing Travel Vouchers
Capturing value from travel vouchers requires discipline at both the traveler and program level.
Centralize tracking. Each unused ticket credit is an expiring asset. Finance teams that don't track these credits will watch them expire. A corporate booking tool that surfaces outstanding credits at the point of purchase removes the manual step from the traveler entirely.
Review voucher terms immediately. Expiration windows, eligible routes, and transferability vary significantly by carrier and voucher type. Reading the conditions when a credit is issued, rather than at rebooking, prevents last-minute surprises when a credit turns out to be non-transferable or restricted to a single destination.
Include credits in T&E budget reviews. Outstanding travel vouchers belong in your active expense report review and T&E budget. Treat them the same way you'd treat a prepaid deposit: real committed value that needs to be consumed before it expires or written off.
Know your rights before accepting. Under current DOT rules, if an airline cancels or significantly changes a flight, passengers are entitled to a cash refund [1]. A voucher is an alternative to that refund, not the only option. Travelers who want the certainty of cash can decline the voucher and request a refund instead.
When Should You Consider Alternatives to Vouchers?
A voucher isn't always the best outcome, even when one is offered.
Request a cash refund when the travel that generated the disruption is unlikely to recur. If a company closes a regional office and no one on the team will travel to that city again, a voucher tied to that destination serves no practical purpose. Under current DOT rules, passengers are entitled to a full cash reimbursement of the original fare when an airline cancels or significantly changes a flight. The DOT rule is explicit: airlines must disclose the right to a refund when offering a credit or voucher as an alternative [1].
Consider keeping the voucher when the face value exceeds the cash alternative. On overbooked flights where carriers request voluntary seat surrenders, flight credits are often offered at a premium over the cash equivalent. If the carrier is one the organization regularly flies, that premium is easily captured on a future booking. Finance teams with preferred carrier agreements get the most from this dynamic: the premium credit applies toward a flight the program would have purchased anyway.
Review expiration terms before deciding. A compensation voucher valid for five years is materially different from an unused ticket credit that expires in 12 months. When evaluating a disruption offer, knowing the expiration window helps determine whether accepting the credit is practical or whether cash is the better option.
A clearly written corporate travel policy resolves most of these decisions in advance. When policy specifies how travelers should respond to disruption offers — which compensation to accept and when to request a cash refund — travel managers avoid ad hoc decisions that result in either unclaimed credits or missed refund opportunities. Building these guidelines into a structured travel policy helps ensure every traveler handles disruptions consistently, regardless of how familiar they are with airline compensation rules.

Frequently Asked Questions About Travel Vouchers
A travel voucher is a document or electronic credit issued by an airline or travel provider that entitles the holder to apply a specified value toward a future booking. Unlike a cash refund, the value stays within the provider's system and comes with expiration dates and usage restrictions that vary by carrier and voucher type.
Yes, most travel vouchers and flight credits carry expiration dates. Unused ticket credits issued when a non-refundable booking is changed or canceled typically expire within 12 months. Under U.S. DOT rules, travel credits offered in lieu of refunds for airline-canceled flights must remain valid for at least five years from the date of issuance.
Airlines issue three main types: compensation vouchers (after cancellations or significant delays), unused ticket credits (when a non-refundable booking changes or cancels), and denied boarding vouchers (offered when passengers voluntarily give up seats on overbooked flights). Promotional vouchers from loyalty programs or partnerships are a fourth category, typically with stricter usage conditions.
Corporate programs should centralize tracking of outstanding credits and surface them at the point of rebooking. Credits that go unapplied before expiration represent lost budget. Navan connects unused ticket credits to the booking workflow, so travelers automatically see available value when searching for replacement flights, eliminating the need to manually track credits across carrier portals.
It depends on the voucher type. Under U.S. DOT rules, travel credits offered in lieu of refunds for disrupted flights must be transferable. However, unused ticket credits issued when a non-refundable fare is changed are typically non-transferable and name-specific — only the original ticketed traveler can use them.
The terms are often used interchangeably. In practice, a travel credit typically refers to a balance held in an account tied to a carrier's booking platform, while a voucher is often a single-use document with a specific face value applied to one booking. Individual airlines define these terms differently, so always review the specific conditions when a credit or voucher is issued.
Navan tracks available unused ticket credits and surfaces them within the booking workflow, so travelers and program managers can apply existing value without manually logging into carrier portals. This helps corporate programs capture credits before they expire, reducing new spend on trips that have existing value from canceled or changed bookings.
Accrual accounting is a method of recording financial transactions when they occur, regardless of when the cash transactions happen, ensuring that revenue and expenses are matched in the period they arise.
