Findings drawn from 300+ distinct sales conversations from itilite’s customer-meeting database, May 2024 through February 2026. Company names are anonymized.
We analyzed 300+ customer sales conversations about unused flight tickets across our customer-meeting dataset. The same four questions came up in nearly every call: where do credits show up, can they transfer between travelers, should the platform auto-apply them or leave that to admins, and how do we stop credits from silently expiring before anyone uses them.
And that’s exactly the reason we decided to talk about unused flight tickets in the context of US business travel. The above-mentioned pattern explains why up to 11% of corporate air spend ends up locked in unused flight tickets each year, even though most travel managers know the problem exists.
Visibility is hard, transfer rules are airline-controlled, and most platforms leave traveler enforcement to manager follow-up.
This guide walks travel managers, finance leads, and procurement teams through what 300+ buyers asked us, how the 2024 DOT refund rule reshaped the legal picture, what each major US airline allows in 2026, and whether expired credits can be written off on taxes.
What are unused flight tickets?
An unused flight ticket is an airline ticket purchased but not redeemed for travel. When a traveler cancels a non-refundable booking, the airline typically converts the value into a flight credit attached to the original traveler’s profile (not to the company). That credit comes with an expiry date and airline-specific rules about who can use it and how.
The terminology is muddled across carriers.
- Delta calls them unused eTickets and Trip Credits.
- American calls them Trip Credits.
- Southwest calls them Flight Credits or Transferable Flight Credits.
- JetBlue calls them Travel Bank credits.
- United calls them Future Flight Credits or Electronic Travel Certificates.
The mechanics differ, but the corporate problem is the same: the credit sits with the traveler, the company paid for it, and someone has to remember to use it before it expires.
A finance lead at an investment-services firm asked us this question directly in a sales call:
“If something gets canceled through your program, what happens? Does the credit go back to our account? Does it go into your account? Is it going to the provider?”
The honest answer is that the credit goes to the airline, attached to the original traveler’s frequent-flyer or airline profile. The company paid, but the airline holds the value, and the traveler controls whether it gets redeemed.
This ownership confusion is the root cause of most unused-credit leakage. Without a system that tracks credits per traveler and surfaces them at the next booking, the credit is functionally invisible to the company that paid for it.
What do travel managers actually ask about unused flight tickets?
We analyzed 300+ distinct customer sales conversations about unused flight tickets across our customer-meeting database from May 2024 through February 2026.
The same four questions came up in nearly every call:
- Where do credits show up (visibility)
- Can credits transfer between travelers (transferability)
- Should the platform (travel booking platform in this case, like itilite) auto-apply credits or leave that to admins (automation versus control)
- How do we stop credits from silently expiring (recovery and expiration)
One interesting fact here is visibility came up in roughly 40% of conversations, more than any other theme.
| Bucket | Share of conversations | Example buyer question |
|---|---|---|
| Visibility | ~40% | Where exactly do credits show up in the booking flow and admin reports? |
| Transferability | ~25% | Can credits move between travelers, or back to the company on termination? |
| Automation vs. control | ~20% | Does the platform auto-apply credits, or do admins keep enforcement? |
| Recovery & expiration | ~15% | How does the system warn us before a credit expires unused? |
Visibility (the 40% question)
What admins ask first: where exactly does the credit show up in the software. Travelers want to see credits during search, before they pick a flight. Admins want a centralized report. A travel admin at a healthcare company asked the three-question version: “Does a credit exist? Where is the credit? How much is it for?” Most platforms answer all three across three surfaces: a tag on the flight-search page, a banner at checkout, and an unused-ticket report on the admin side.
Transferability (the #1 anxiety)
Transferability is where buyers consistently get the disappointing answer. A travel coordinator at a healthcare staffing firm asked: “Can I use them for other people?” The default answer across every major airline is NO.
Credits are issued to the original traveler at the airline level. Transfer requires either a corporate airline contract that explicitly permits it or, in 2025, Delta’s new Unused Ticket Transfer (UATP) program. This was the top anxiety in 30+ of our 300+ conversations.
Automation vs. control
Some buyers want the platform to auto-apply credits at checkout with no traveler decision. Others want admin-side enforcement, meaning a hard rule that travelers must use available credits before booking new tickets. A controller at a real estate firm asked: “Is there a way for us to mandate that?” The honest answer is that no major travel platform (like itilite) currently mandates credit usage at the system level. Reporting flags non-usage, but enforcement still relies on manager follow-up.
Recovery & expiration
The fourth bucket is the operational pain itself. How does the system prevent a credit from expiring unused? The standard answer across modern platforms: surface available credits at every booking attempt and flag credits within 90 days of expiry in admin reports. The buyers who raised this question almost always followed up by asking about reporting cadence.
How much money do unused flight tickets cost companies?
Unused flight tickets cost companies (approx) 5 and 11% of annual corporate air spend. For a $5 million air program, that is $250,000 to $550,000 trapped in airline credits each year. The leakage is rarely spotted because finance does not see it as a line item.
The macro context makes the dollars real. US business travel spend is projected to reach $395.4 billion in 2025. Skift Research’s 2025 corporate travel survey found that 54% of travel managers say their booking tools struggle with unused tickets, and 64% cite exchanges and cancellations as a chronic pain point
| Management maturity | Annual leakage rate (industry estimate) |
|---|---|
| Unmanaged (no platform tracking) | ~11% |
| Semi-managed (manual spreadsheet tracking) | ~6% |
| Automated (T&E platform with credit surfacing) | ~2% |
What does the 2024 DOT refund rule mean for unused flight tickets?
The US Department of Transportation Final Rule on automatic refunds took effect October 28, 2024.
It requires airlines to issue cash refunds, not vouchers, when they cancel or significantly change a flight. The refund must reach a credit-card buyer within 7 business days, or within 20 calendar days for other payment methods. When the airline offers a voucher or credit instead of a refund, the credit must be valid for at least 5 years from the date of issuance.
This is the single most important regulatory shift for unused flight credits in the last decade. It changes the math on involuntarily canceled flights. Where corporate programs once accepted vouchers as the standard outcome, the rule now favors cash refunds for any flight the airline cancels or shifts by more than 3 hours domestic or 6 hours international.
The 24-hour cancellation rule still applies separately. For tickets purchased at least 7 days before departure, airlines must allow a full refund or hold within 24 hours of booking. This is the cleanest tactical lever for a travel manager who realizes a booking is wrong before the day-old window closes.
Three takeaways for travel programs in 2026:
- For any airline-canceled or significantly delayed flight after October 28, 2024, demand the cash refund first. Accept a credit only if the cash path fails.
- When a credit is the only option, the 5-year validity floor means there is far more time to apply it. Build the recovery workflow around the new floor, not the old 12-month default.
- Voluntary cancellations still produce traveler-bound credits with airline-specific expiry. The DOT rule does not change that.
What are each US airline’s unused ticket policies?
A managing director of aviation at an investment management firm summed up the typical buyer’s mental model: “You got a year to use them or something, right?” Roughly correct, but each major carrier runs a different rulebook. Some allow transfer, most do not. Some publish separate consumer and corporate policies. Most have changed their rules in the last 24 months.
Here is the side-by-side for the top 5 US airlines as of 2026.
| Airline | Credit name | Validity | Transfer | Name change | 2024 to 2026 changes |
|---|---|---|---|---|---|
| Delta | Unused eTicket / Trip Credit | 12 months from original ticketing | UATP transfer (corporate, 2025) | Free for corporate accounts | Launched Unused Ticket Transfer (UATP) program in 2025; first US legacy carrier to allow corporate-level credit transfer |
| United | Future Flight Credit; Electronic Travel Certificate | FFC: 12 months; ETC: 24 months | Limited; corporate program required | Corporate program | Stable policy; corporate accounts get more flexibility |
| American | Trip Credit | 12 months for AAdvantage members; 6 months for non-members | Limited | Free for corporate | Trip Credit split introduced on April 2, 2024 |
| Southwest | Flight Credit; Transferable Flight Credit | Basic: 6 months from booking; Transferable: 12 months | Yes, for Transferable Flight Credit | Yes | Major shift effective May 28, 2025; pre-May 28, 2025 credits remain non-expiring |
| JetBlue | Travel Bank | 12 months from original ticketing date | No extensions or transfers | No | Policy effective March 8, 2023, still current |
How do you redeem and recover unused flight credits?
A working recovery process surfaces credits at the moment of booking, so no one has to remember they exist. The five steps below describe what that process looks like in 2026.
Step 1. Inventory monthly
Pull every credit from every airline portal at least once a month. Match each credit to a traveler, ticket number, and expiry date. If your team is doing this in a spreadsheet, you are doing it the way most unmanaged programs do it, and you are losing credits to expiry.
Step 2. Prioritize by expiry
Flag any credit within 90 days of expiry as a pre-trip applicable credit. Set up a recurring report that lists every credit by traveler, sorted by days remaining. Most modern T&E platforms include a 90-day warning by default.
Step 3. Apply at booking, not after
Surface credits on the search-results page, not after the booking is complete. The customer pattern from our 300+ conversations was consistent: visibility at three points, search tag, checkout, and admin report, is what travel managers asked for over and over.
Step 4. Recover departed-employee credits
For credits attached to terminated employees, route through your corporate program. Free name changes are now standard at Delta, American, and United on corporate-program tickets. For Delta specifically, request UATP transfer to the corporate UATP card.
Step 5. Pursue cash refunds for canceled flights
For any flight the airline canceled or significantly changed after October 28, 2024, demand the cash refund per the DOT Final Rule. Accept a credit only if the costless cancellation path fails. The 5-year voucher floor applies if you do accept.
How do automated travel platforms manage unused tickets?
A travel admin at a healthcare company asked the simplest version of the visibility question: “Does a credit exist? Where is the credit? How much is it for?” A working automated platform answers all three before a traveler picks a flight. Modern T&E systems track credits per traveler per airline, surface available credits on the flight-search page, apply them at checkout, and feed an admin report listing every outstanding credit with its expiry date.
| Capability | ITILITE |
|---|---|
| Search-time credit surfacing | Yes |
| Checkout auto-application | Yes (default) |
| Admin unused-ticket report | Yes |
| Multi-airline aggregation | Yes |
| 24/7 human support for credit questions | 24/7 human, sub-30-second response |
The reconciliation model built into corporate travel platforms (like itilite) captures unused credits at the same time. That timing difference is what closes the silent-leakage loop most travel managers struggle with.
Can you write off expired flight credits on your taxes?
Expired flight credits may be deductible two ways. Under IRC Section 162, the original ticket counts as an ordinary business expense in the year incurred. Under IRC Section 165, an expired credit can be claimed as a loss when it becomes worthless. Section 162(a) covers ordinary and necessary business expenses paid or incurred during the taxable year. Section 165 requires evidence of a closed and completed transaction fixed by an identifiable event
Two practical implications for finance teams here:
- First, if the credit is still alive on the books, it is an asset, not a loss. The deduction was already taken when the ticket was purchased and expensed.
- Second, when the credit actually expires unused and worthless, that is the identifiable event the loss-recognition rule looks for.
IRS Publication 463 is the primary IRS guidance on business travel deductibility. Combined with Section 162 and Section 165, the framework allows companies to take the expense at purchase, recognize the loss at expiry, and avoid double-counting the same dollar.
