What Are the Flight Rules for Child Passengers?

Traveling with children can be both exciting and requires extra planning. Airlines implement specific standards and rules to ensure that young travelers have a safe and comfortable journey. From age categories and document checks to baggage allowances and unaccompanied travel limits, many regulations differ from adult travel rules.

To avoid surprises at the airport or during the flight, we have compiled all the details you need to know about flight rules for child passengers in this guide.

What Do Flight Rules for Child Passengers Cover?

Flight rules primarily focus on the safety of children, their comfort during travel, and ensuring legal procedures are properly followed. These rules cover a wide range of issues, from how many days old a baby must be to fly, which seat the child can sit in, the liquids or baby food allowed on board, to the conditions under which a child can travel alone.

How Are Age Limits for Child Passengers Determined?

Airlines legally categorize young passengers into two main groups: "Infant Passenger" and "Child Passenger." The rules, ticket pricing, and seat rights for these two categories are completely different.

Infant Passenger Flight Rules

Passengers who have not yet reached their 2nd birthday (0–2 years) are considered infant passengers. According to flight rules for infants, a baby must be at least 7 days old to be accepted on a flight. Infants travel on their guardian’s lap using a special infant seatbelt. If you want your baby to have a separate seat, you can purchase a child ticket and use a car-type infant seat (car seat). For safety reasons, one adult may only hold one infant on their lap during the flight.

Child Passenger Flight Rules

Passengers aged 2–12 are considered child passengers. Children in this age group must have their own seat and cannot sit on an adult’s lap. Child tickets are usually offered at a discounted rate compared to adult tickets, typically ranging between 25% and 33%, depending on the airline’s policy.

How to Book a Flight Ticket for a Child Passenger

Infant and child tickets cannot be purchased alone online. Airline systems require child tickets to be paired with at least one adult ticket. When booking online, select "Child" or "Infant" under the passenger count section and enter the accompanying adult’s information. If you have already booked your ticket and want to add your child later, you can do so by calling the airline’s customer service center.

Can Children Fly Alone?

Children above a certain age can travel without their parents. Airlines provide special services to ensure the safety of unaccompanied minors.

Unaccompanied Minor (UM) Rules

Generally, children aged 5–12 can travel as unaccompanied minors with parental consent. In this service, the child is handed over by their family at the airport, escorted to the aircraft by flight attendants, supervised throughout the flight, and delivered at the destination to a pre-designated person whose ID matches the records. This service usually requires an application at least 48 hours before the flight and an additional service fee. Children aged 12–18 may use this service optionally or travel entirely independently.

Required Documents for Child Passengers

For legal procedures and to prevent child abduction, airlines and border authorities are strict about document checks.

Domestic Flights

For domestic flights, child and infant passengers must carry an official ID showing their Turkish ID number (identity card or passport). Newborns may use their birth certificate for the first few weeks, but it is recommended to obtain an ID as soon as possible. Photos are generally not required for children under 15.

International Flights

For international travel, a child must have a valid passport and the visa of the destination country (if required). A critical rule is the consent form. If the child is traveling with only one parent, the other parent must provide a notarized travel consent. If neither parent is traveling, both parents must give notarized consent. Otherwise, the child will not be allowed to leave the country.

Baggage Allowance for Child Passengers

Children with their own seat are entitled to the same baggage allowance as adults. The weight limit allowed for your ticket class (e.g., 20 kg) also applies to the child’s suitcase.

For infants traveling on an adult’s lap, a limited 10 kg under-seat allowance is generally provided. Most airlines allow one collapsible stroller or pushchair per infant or child to be transported free of charge in the cargo hold. You can use the stroller up to the aircraft door and hand it over to staff before boarding.

Tips Before Flying with Children

• Liquid Restrictions Exception: The 100 ml liquid rule does not apply to baby food and milk. You can bring as much as needed for the flight, but you may need to show these items at security.
• Pressure Changes: Takeoff and landing can cause ear discomfort for children. Feeding infants, giving a bottle, or having older children chew gum helps equalize ear pressure.
• Arrive Early: With children, document checks and baggage procedures may take longer. Arriving at least 2–3 hours before departure reduces stress.

Seat Selection and Safety Rules

Children and infants are not allowed to sit in emergency exit rows due to safety regulations. Airlines strive to seat families together during check-in. Some planes offer bassinets that can be mounted on front walls; to use this service, reserve the seat quickly after ticketing.

Frequently Asked Questions About Child Passenger Flight Rules

Can I take a stroller onto the plane?
Strollers are usually checked at the aircraft door and stored in the cargo hold. Some foldable strollers that fit cabin baggage dimensions may be allowed on board.

Does my child’s ID need a photo?
For domestic flights, children under 15 do not need a photo on their ID. For international flights, a passport is required, which includes a photo.

What about children of divorced parents traveling abroad?
Even if the custodial parent is traveling, some countries and Turkish border authorities may request a notarized travel consent from the non-traveling parent. To avoid delays or complications, always carry the consent form.
