Yes, you can typically cancel a ticket for a single passenger even if they are part of a multi-person booking (PNR). To do this, the airline must perform a process called "splitting the PNR" or "dividing the booking." You can often do this through the airline's "Manage My Booking" portal by selecting the specific traveler you wish to remove. Once the individual is split into their own separate booking record, their ticket can be cancelled according to the original fare rules. If the ticket was "Non-Refundable," you will likely receive a Travel Credit in that passenger's name rather than a cash refund. It is important to note that if you used a companion fare or a "buy-one-get-one" promotion, cancelling one person may invalidate the discount for the remaining traveler or trigger a fare recalculation. In 2026, most major carriers allow this to be done digitally, but for complex itineraries or those booked through third-party travel agents (like Expedia), you may need to call customer service to ensure the "split" is handled correctly without affecting the other travelers.
