An airline charge applied when a passenger modifies a confirmed booking after the ticket is issued. The modification may involve adjusting the date, time, route, or destination. The fee amount depends on fare type and carrier policy — some airlines have eliminated change fees on standard fares while preserving restrictions on basic economy tickets.
A change fee is an airline charge applied when a traveler modifies a confirmed booking — adjusting the flight date, time, or route after the ticket is issued. The fee amount and whether it applies at all depend on the fare type and carrier policy.
Most major U.S. airlines have eliminated change fees on standard economy and above fares, but basic economy tickets remain largely non-changeable or carry significant penalties.
A change fee and a fare difference are two separate costs. Even when a carrier waives the change fee, travelers still owe any price gap between the original ticket and the new one.
U.S. Department of Transportation rules require airlines to issue automatic refunds when they cancel or significantly change a flight — travelers are not responsible for fees when the disruption originates from the carrier [1].
Navan displays fare rules and change conditions before booking confirmation, giving travelers and travel managers full visibility into ticket flexibility before purchase.
Corporate travel policies that define fare flexibility requirements by trip type can substantially reduce unplanned change fee exposure across a travel program.
What is a Change Fee?
A change fee is a charge an airline imposes when a passenger modifies a confirmed reservation after the ticket is issued. Common modifications include changing the departure or return date, adjusting the departure time, switching routes, or updating the destination.
Change fees are distinct from fare rules that prohibit changes entirely. On the most restrictive fare types, a change simply isn't permitted. The ticket is use-or-lose. On fares where changes are allowed, the airline collects a flat administrative charge or waives it based on its current policy.
In corporate travel, change fees come up regularly because business schedules shift. A meeting gets rescheduled, a deal closes early, or a client engagement extends. Any of these can force a flight modification after a ticket is already confirmed. Knowing when a fee applies, how much it costs, and when it can be avoided helps both travelers and finance teams manage this expense proactively.
What Determines a Change Fee Amount?
The fare class of the ticket is the primary variable. Within any given cabin — economy, business, first — different fare buckets carry sharply different modification rules.
Basic economy fares carry the strictest restrictions. Most major U.S. carriers either prohibit changes entirely on these fares or charge a substantial penalty. Travelers who book the cheapest available option without reviewing fare conditions often discover this restriction only when plans change.
Main cabin and standard economy fares have relaxed significantly since most major U.S. carriers eliminated change fees on these fare types. The modification itself is free administratively, though any fare difference between the original and new ticket is still due.
Flexible and refundable fares allow unlimited changes and full cash refunds on cancellation. The upfront price is higher, but for travelers with genuinely uncertain schedules, the flexibility often justifies the premium.
Business class and first class have also seen unbundling in 2025–2026, with several carriers introducing entry-level tier pricing within premium cabins. A business class ticket in the base tier may now carry change restrictions that historically didn't exist in premium cabins, a shift that matters for corporate travel programs that assume all premium fares include full flexibility.
Change Fee vs. Fare Difference: What's the Real Cost?
Conflating the change fee with the total cost of a modification is one of the most common misunderstandings in this area. They're two separate line items.
The change fee is the administrative charge the airline collects to process the modification. Many carriers have set this to zero on standard fares.
The fare difference is the price gap between the original ticket and the new one. If a traveler paid $320 for a Tuesday flight and needs to move to a Thursday flight priced at $490, the $170 fare difference is owed, regardless of whether a formal change fee applies. This cost is always present when moving to a higher-priced flight.
For finance teams tracking travel and expense reimbursements, logging change fees and fare differences as separate expense categories gives clearer visibility into modification costs and informs whether policy adjustments would reduce overall spending.
When Airlines Must Waive Change Fees
Passengers have legal protections when a flight modification originates from the airline rather than the traveler. Under U.S. Department of Transportation rules, airlines operating flights to, from, or within the United States must provide automatic refunds when they cancel a flight or make a "significant change" [1].
Changes that meet the DOT definition of significant include:
Departure or arrival delays of more than 3 hours on domestic flights (6 hours on international routes)
A change to a different departure or arrival airport
An increase in the number of connections
A downgrade in cabin class
When these conditions apply and the traveler chooses not to accept the modified itinerary, the airline must issue a full cash refund to the original form of payment. A travel voucher or credit doesn't satisfy the requirement.
The DOT also maintains a 24-hour rule: passengers who book directly with an airline at least 7 days before departure can cancel within 24 hours of purchase at no charge, regardless of fare type [1].
Managing Change Fees in a Corporate Travel Program
How a company addresses change fees in its corporate travel policy has a direct effect on T&E costs. Three approaches are most common, each trading upfront fare cost against downstream modification exposure.
Mandate flexible fares universally. Requiring refundable or flexible tickets for all bookings eliminates change fee risk but raises average ticket costs. This suits organizations where travelers frequently modify itineraries or where the downstream cost of a missed meeting outweighs the fare premium.
Allow any fare, reimburse only approved changes. This keeps base ticket costs lower and avoids spending a premium on fares for trips that won't change. Finance teams review change fee and fare difference reimbursements case by case, which creates processing overhead but surfaces which trips generate the most modifications.
Tier by trip type. Many mature travel programs apply flexible fare requirements selectively: required for client-facing or international travel where schedule changes are common, optional for internal or short-haul routes where departures are predictable. This balances cost efficiency with operational flexibility.
Travel policy compliance tracking is essential across all three approaches. Without visibility into which bookings fall inside or outside policy, finance teams can't measure whether change fee exposure is improving over time or identify which departments generate the most modifications.
Reducing Change Fee Exposure
The practical steps for reducing change fee costs are straightforward, though they require discipline at the time of booking.
Check fare rules before confirming. Fare conditions are visible during the booking process. Reviewing them before purchase prevents the common mistake of booking a restricted fare without recognizing its modification limits.
Use the 24-hour cancellation window. On direct airline bookings, travelers can cancel for free within 24 hours of purchase if the flight departs at least 7 days later. This window provides a brief opportunity to reconsider a booking when plans are still uncertain [1].
Match fare flexibility to trip certainty. Travelers heading to a confirmed meeting on a fixed date can book standard fares without risk. Travelers whose trips depend on negotiations, approvals, or milestones that haven't finalized should either book a flexible fare or delay purchasing until the schedule is settled.
Track unused ticket credits. When a non-refundable ticket is canceled before departure, many carriers issue a travel credit rather than a refund. Tracking and using those credits before expiration recovers value that would otherwise be forfeited. Navan surfaces unused ticket credits automatically during the booking flow, preventing travelers from leaving stranded value on the table.
Related Terms
Non-refundable ticket: A fare that can't be returned for cash if the traveler cancels. Non-refundable tickets may still permit changes under specific conditions; the change and refund rules are specified separately in the fare conditions.
Refundable ticket: A fare that allows cancellation with a full cash refund, typically without change fees. Refundable tickets carry a higher base cost but eliminate financial exposure from both itinerary changes and cancellations.
Fare class: The letter-code designation grouping tickets within a cabin by price and flexibility rules. Fare class is the primary factor determining whether a change fee applies and how large it is. The same physical seat can carry sharply different modification terms depending on the fare bucket.
Corporate travel policy: A company's formal framework governing how employees book, spend on, and get reimbursed for business travel. A well-written policy specifies permitted fare types and whether change fees are reimbursable.
Travel policy compliance: The degree to which employee bookings follow a company's defined travel rules. Compliance tracking helps identify which travelers or departments generate disproportionate change fee exposure.

Frequently Asked Questions About Change Fees
A change fee is an airline charge for modifying a confirmed booking — adjusting the date, time, route, or destination after the ticket is issued. The fee depends on fare type and carrier policy. On most standard economy fares at major U.S. carriers, the administrative change fee has been eliminated, though travelers still owe any fare difference between the original and new ticket.
A change fee is the administrative charge for processing a modification. A fare difference is the price gap between the original ticket and the new one. Even when the change fee is waived, travelers owe any fare difference. On a route or date change close to departure, the fare difference can be substantial — often larger than any traditional change fee would have been.
Most major U.S. airlines waive change fees on standard economy and above fares, so the modification itself is free — though fare differences still apply. All passengers booking directly with an airline can also cancel within 24 hours of purchase (for flights at least 7 days away) for a full refund. Basic economy fares typically don't qualify for either waiver.
No. Under DOT rules, airlines operating U.S. flights must issue automatic cash refunds when they cancel a flight or make a significant change — such as delays over 3 hours domestically (6 hours internationally), an airport change, or a cabin downgrade. Travelers who decline the modified itinerary are entitled to a full cash refund, not a travel credit.
Corporate travel platforms reduce change fee exposure by surfacing fare restrictions before booking, so travelers evaluate flexibility alongside price. Navan displays change and cancellation conditions during the booking process and surfaces unused ticket credits from prior cancellations so travelers don't leave stranded value on the table. Travel managers can also configure policy rules to guide travelers toward compliant fare choices before purchase.
A change fee applies when a traveler modifies an existing booking — adjusting dates, times, or routes. A cancellation fee applies when a traveler cancels outright. Some fares charge for both; others waive changes but still impose a cancellation penalty. For non-refundable tickets, cancellation typically means forfeiting the remaining ticket value rather than paying a discrete fee.
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.
