What Is Overbooking (Double Booking)? What Are Your Rights If You Are Affected?

What Is Overbooking?
Overbooking is a practice in which airlines sell more tickets than the number of seats available on an aircraft, based on the assumption that some passengers may not show up for their flights. The aim is to avoid empty seats. However, if all passengers show up for the flight, the aircraft may exceed its capacity and some passengers may be denied boarding.
Why Do Airlines Use Overbooking?
Airlines use overbooking to reduce revenue losses caused by canceled or unused tickets. Although this practice is based on statistical estimates, poor management can result in passenger inconvenience and disruption.
Is Overbooking Legal?
Overbooking may be permitted in many countries under certain rules and regulations. However, if a passenger is denied boarding against their will, the airline must comply with applicable passenger rights regulations.
Difference Between Overbooking and Flight Cancellation
A flight cancellation occurs when an airline does not operate a scheduled flight. Overbooking, on the other hand, occurs when the flight operates but some passengers are denied boarding because there are not enough seats available.
What Happens in an Overbooking Situation?
What Is Denied Boarding?
Denied boarding occurs when a passenger with a valid ticket and reservation is not allowed to board the aircraft due to insufficient capacity. This situation is generally caused by overbooking.
How Does the Process of Seeking Volunteers Work?
Airlines may first ask passengers to voluntarily give up their seats and take a later flight in exchange for certain benefits, compensation, or other advantages.
What Happens to Passengers Who Are Denied Boarding Involuntarily?
If there are not enough volunteers, some passengers may be denied boarding involuntarily. In such cases, passengers may be entitled to an alternative flight, assistance services, and, depending on the circumstances, financial compensation.

What Are Your Rights If You Are Denied Boarding Due to Overbooking?
Right to Request an Alternative Flight
Passengers may request a suitable alternative flight to reach their destination. The airline should provide a new transportation option as soon as reasonably possible.
Right to Request a Ticket Refund
Passengers who no longer wish to continue their journey may, in certain circumstances, request a refund for the unused portion of their ticket.
Services That Should Be Provided During the Waiting Period
Depending on the length of the waiting period, passengers may be entitled to food, beverages, communication assistance, and, when necessary, accommodation.
Right to Claim Compensation
Passengers who are involuntarily denied boarding due to overbooking may be entitled to financial compensation if the applicable legal requirements are met.
When Can You Receive Compensation?
Rules for Domestic Flights
In Türkiye, passenger rights are assessed under the relevant aviation regulations depending on the nature of the flight and the circumstances of the inconvenience experienced. Passengers who are denied boarding may have certain rights.
Passenger Rights for Flights Covered by European Union Rules
Under EU rules, passengers on flights that meet certain conditions may be entitled to alternative transportation, care and assistance services, and compensation when they are denied boarding due to overbooking.
Effect of Extraordinary Circumstances on Compensation
Extraordinary circumstances such as severe weather conditions, security issues, or events beyond the airline's control may affect certain compensation claims.
What Should You Do in an Overbooking Situation?
Speak to Airline Representatives at the Airport
If you experience inconvenience, contact airline staff and ask for information about your rights and available options.
Request Written Documentation and an Explanation
Ask for a document, explanation, or record stating why you were denied boarding. This can be important if you need to make a claim later.
Keep Your Boarding Pass and Reservation Documents
Keep your ticket, reservation confirmation, check-in information, and receipts for any expenses you incur. These documents may be useful when making a claim.

Application Process with the Airline

What Documents Are Required?
You will generally need your ticket details, reservation records, identification information, flight documents, and, where applicable, receipts for additional expenses.
What Can You Do If Your Claim Is Rejected?
If your claim is rejected, you may consider pursuing additional remedies through relevant consumer protection authorities or civil aviation institutions.
How Can You Reduce the Risk of Overbooking?
