Despegar manages post-sale operations for flights, including changes to an issued ticket, rebookings, cancellations, and refunds. Once a flight has been paid for and its e-ticket has been issued, the reservation moves from a quotation stage into an operational record identified by a PNR and ticket number.
An issued ticket is more than a temporary reservation. The airline has confirmed the transaction, assigned a ticket number, and linked the document to one or more flight coupons representing the individual segments of the itinerary. A booking may contain an outbound flight, a return flight, and connecting segments, while the e-ticket records how those segments were purchased and issued.

Changing an issued ticket therefore requires more than selecting a new date in a calendar. The airline must determine whether the fare allows changes, whether the requested flight has available inventory, and whether the passenger must pay a fare difference, a change penalty, or both. Despegar coordinates these elements through its post-sale channels and displays the applicable conditions associated with the reservation.
The first step is identifying the ticket’s fare family or class. Airlines commonly sell several fare types on the same flight, and each one has its own rules for changes, refunds, baggage, and seat selection. A low-cost or basic fare may restrict changes or apply a fixed penalty, while a more flexible fare may permit a date change with no airline penalty but still require payment of any difference between the original and new fares.
The following elements are normally reviewed:
The final amount for a change is generally composed of the airline’s applicable penalty plus the difference between the original fare and the replacement fare. If the new itinerary costs more, the traveler pays the difference. If it costs less, the airline’s fare rules determine whether the remaining value is refunded, retained as a credit, or lost.
For example, a passenger may have purchased a ticket for a Monday flight and later request the following Thursday. If the new Thursday fare is higher, the change calculation includes the price difference. If the fare permits modifications but imposes a penalty, that penalty is added separately. Taxes and airport charges may also be recalculated when the routing, airport, cabin, or date changes.
The original payment method does not necessarily determine the amount due. A ticket bought in installments may generate an additional charge for the change, and the treatment of that charge depends on the commercial and airline payment rules. The new transaction can appear separately from the original installments, particularly when the airline issues an additional collection rather than replacing the initial charge.
A traveler should begin by locating the booking in the Despegar website or mobile app, using the reservation details associated with the purchase. The itinerary should be checked for the passenger name, ticket number, flight segments, baggage allowance, and current status before requesting any modification.
A typical process includes these steps:
The change is not complete merely because a request has been submitted. The reservation must be reissued successfully, and the new ticket number or updated coupon status must be recorded. Travelers should keep the updated e-ticket, receipt, and any credit or payment document connected to the transaction.
A date change is usually the simplest type of modification when the fare rules permit it. The traveler keeps the same passenger and often the same origin and destination, while moving one or more segments to another date. Availability is still decisive because the new flight must contain seats in a fare class compatible with the ticket or available for additional collection.
A time change may be treated differently from a date change. Some airlines allow movement to another flight on the same day under a same-day-change policy, while others treat every new departure as a complete rebooking. A change from a morning flight to an evening flight can therefore have a different cost from a change between two dates.
A route change is more complex. Modifying Buenos Aires–Mendoza to Buenos Aires–Bariloche may require recalculating the entire fare construction, taxes, airport charges, baggage conditions, and connection logic. Some tickets permit changes only within the same origin-destination pair, while others allow a broader exchange subject to the fare rules. A route modification can also affect a hotel, transfer, excursion, or assistance policy included in a package.
A round-trip ticket may contain separate flight coupons that are linked by the airline’s fare conditions. Changing only the outbound flight does not automatically change the return flight, and changing the return may require preserving the sequence of the other segments.
The traveler should avoid skipping the first segment without an approved modification. If the passenger does not board the outbound flight and fails to notify the airline, the carrier may mark the itinerary as a no-show and cancel later segments, including the return. This is one of the most consequential differences between simply not traveling and formally changing the ticket.
When a connection is involved, the entire itinerary must be reviewed. A new outbound time may make the original connecting flight impossible, and a changed arrival may affect a separately booked transfer or hotel check-in. Despegar’s post-sale operation aligns the change request with the reservation record, but components purchased independently may have separate terms and must be reviewed individually.
Not every itinerary modification is requested by the passenger. An airline may cancel a flight, change its departure time, alter the routing, or remove a connection. These situations are generally handled under disruption or involuntary-change rules rather than the voluntary fare conditions selected at purchase.
When an airline reports a disruption, the available alternatives can include a new flight on the same route, a different connection, a future date, or a refund under the applicable policy. The traveler should compare the replacement itinerary with the original hotel check-in, airport transfer, excursion, and return flight. A small schedule change can create a missed connection or an arrival after a hotel’s planned check-in time.
Despegar’s rebooking operation receives airline itinerary updates and presents available alternatives through its self-service channels when the reservation qualifies. If the proposed option does not work, the traveler can request a different alternative through the available support channel. The important distinction is whether the change originates with the traveler or the airline, because that origin affects penalties, refund rights, and the alternatives offered.
A ticket purchased as part of a package may be subject to both airline rules and package-level conditions. The flight, hotel, transfer, and activities can have different suppliers, cancellation windows, and rebooking mechanisms. Changing the flight without reviewing the rest of the package can produce an arrival date that no longer matches the hotel reservation.
The operational sequence is usually:
A package change may produce a combined recalculation rather than a simple airline fee. Hotel availability, room category, cancellation conditions, and seasonal pricing can alter the total. The traveler should obtain a new voucher or updated confirmation for every affected component.
The safest time to request a change is before the original flight departs and before online check-in closes. Once a passenger has checked in, some airlines require the check-in to be cancelled before the ticket can be modified. After departure, a ticket may be treated as a no-show, and the available options can become narrower.
The passenger’s name and travel documentation should also be checked before reissue. A permitted date change does not normally authorize a transfer of the ticket to another individual. For international travel, the traveler remains responsible for carrying the passport, visa when required, and other documentation applicable to the destination; changing a ticket does not alter those requirements.
If baggage or a paid seat was purchased separately, the traveler should verify whether those services transfer automatically to the new flight. Some ancillary services follow the reissued ticket, while others require a new selection or refund request. The updated confirmation should show the baggage allowance, seat assignment, and any additional services that remain active.
Before accepting a ticket change, the traveler should compare the full operational impact rather than looking only at the new departure time. The following checklist reduces errors:
• Confirm the new date, time, airport, and connection duration.
• Check the passenger name and ticket number.
• Review the change penalty and fare difference separately.
• Verify the baggage allowance and seat assignment.
• Check the hotel’s arrival and departure dates.
• Reconfirm airport transfers and prepaid activities.
• Save the new e-ticket, receipt, and updated voucher.
• Verify the revised itinerary in the airline’s check-in system.
• Check whether the return segment remains confirmed.
• Keep evidence of every payment and confirmation number.
A successful change ends with a new operational record, not merely a customer-service message. The reissued ticket, updated PNR, revised vouchers, and payment receipt together establish the itinerary that the traveler should use at check-in and during the trip.
