United Airlines Infant Policy

Flying with an infant can feel overwhelming, especially if it’s your child’s first flight. United Airlines understands the challenges parents face when traveling with babies and toddlers, which is why it has established a clear set of rules and amenities designed to make the journey smoother. The United Airlines infant policy covers everything from lap infant travel and ticketing rules to bassinets, baggage allowances, and international requirements.

This guide provides a complete breakdown of United Airlines infant policy so parents can prepare confidently before heading to the airport.

Overview of United Airlines Infant Travel

For ticketing and travel purposes, United Airlines defines an infant as a child under two years of age at the time of travel. Parents or guardians have two options:

• Lap Infant Travel – The infant shares the seat with an adult, usually free for domestic travel, though international flights may require a fee.
• Separate Seat with Safety Seat – Parents can purchase a ticket for the infant and use a government-approved child safety seat. This option provides added safety and comfort, especially on long flights.

United infant policy ensures compliance with FAA regulations while giving families the flexibility to choose what works best for them.

Lap Infant Travel Rules

United allows passengers to travel with infants on their laps, provided the child is under two years old.

• Domestic Flights: On flights within the U.S., lap infants travel free of charge. Parents simply need to add the infant’s details during booking or at check-in.
• International Flights: For international routes, United charges a fee for lap infants. Typically, this is calculated as 10% of the adult fare plus applicable taxes and surcharges. The exact amount varies depending on the route and destination.

Important Considerations for Lap Infants

• Each adult can only travel with one lap infant. If traveling with two children under two, a seat must be purchased for the second child.
• Infants must remain in the adult’s lap during takeoff, landing, and turbulence.
• Some long-haul flights may require passengers with lap infants to sit in designated seating zones for safety.

Traveling with Multiple Infants

If a parent or guardian is traveling with more than one infant, United Airlines requires that one of the infants must have a separate seat. In that case, an FAA-approved child safety seat must be used for the second child. This ensures that both infants can travel safely without compromising airline safety standards.

For example, a parent flying from New York to London with twins will need to purchase one additional seat since only one child can be held as a lap infant.

Note: If you ever spot errors on your booking while traveling with your child, United Airlines allows passengers to request Name Correction On United Ticket. Ensuring names match travel documents is essential, especially for international flights, to avoid delays or denied boarding during your journey.

Child Safety Seats

United strongly recommends the use of child safety seats, even if lap infant travel is allowed. Safety seats provide added protection in case of turbulence and give infants a secure place to rest during long journeys.

• Approved Seats: Only FAA-approved child safety seats are allowed. They must display a label stating that they are certified for use on aircraft.
• Placement Rules: Child seats must be installed in a window seat so they do not block access for other passengers.
• Size Restrictions: Seats must fit within the dimensions of the aircraft seat. Oversized seats may not be permitted.

Parents are responsible for correctly installing the seat according to the manufacturer's instructions.

United Airlines Bassinet Policy

For long-haul international flights, United provides bassinets (also called sky cots) to help infants rest comfortably.

• Availability: Bassinets are available only on select aircraft and specific seating rows, usually the bulkhead seats.
• Reservations: They must be requested in advance by calling United Airlines. First-come, first-served is the rule for limited availability.
• Size & Weight Limits: Generally suitable for infants weighing up to 22 lbs (10 kg). Infants must also fit within the bassinet’s length and width restrictions.

Since bassinets cannot be guaranteed at check-in, parents should always confirm during booking if this service is essential.

Infant Baggage Allowance

United Airlines recognizes that traveling with infants requires extra items such as strollers, car seats, and diaper bags.

• Lap Infants: Allowed one diaper bag in addition to the adult’s standard carry-on allowance.
• Ticketed Infants (with their own seat): Receive the same baggage allowance as the purchased fare class.
• Strollers and Car Seats: One stroller and one car seat per child may be checked free of charge. Passengers can check them at the gate or during regular check-in.

This generous allowance helps parents avoid extra baggage fees when traveling with young children. That said, your standard checked bags on top of the stroller and car seat still follow United's normal fee structure on domestic routes. Before you pack, check the full United Airlines baggage fees for domestic flights so you know exactly what each additional bag will cost and can decide whether to consolidate or pay for an extra one.

Booking and Check-In for Infants

When booking flights, passengers must indicate that they are traveling with an infant. This ensures that proper seating and services are arranged.

• Domestic Flights: Proof of age may be required at check-in, such as a birth certificate.
• International Flights: Infants must have a passport, and in some cases, a visa depending on the destination country.
• Boarding Passes: Lap infants do not receive a separate boarding pass, but their name will appear on the adult’s ticket.

Note: Parents should be aware that flight changes or cancellations may result in a United Airlines Cancellation Fee depending on the fare type. Reviewing the policy before booking ensures you understand potential costs and options for refunds or travel credits, which is especially important when traveling with infants.

International Infant Travel Guidelines

For international flights, the United Airlines infant policy has additional requirements:

• Infants must have their own passports and required travel documents.
• Lap infant fees are applied at 10% of the adult fare plus taxes.
• On many international flights, bassinets may be requested, but availability is not guaranteed.
• Some countries require documentation showing proof of parental consent if only one parent is traveling with the child.
• Parents should always check entry requirements for their destination well in advance of travel.

When traveling with an infant, you may realize that your travel dates or flight times need to change after booking. To understand the fees or fare differences that may apply, check out our guide on the cost to change a United flight.

United Airlines No-Show Policy for Infants

If a parent books a flight with an infant and fails to show up without canceling, the value of the ticket may be forfeited. For international flights, this can mean losing the lap infant fare as well. To avoid losing money, passengers should cancel or modify the reservation in advance.

Infant Meals and In-Flight Services

While infants are not provided with full meals, United Airlines offers several services to make flights more convenient:

• Hot water for formula preparation is available upon request.
• Some long-haul flights may provide basic baby amenities if requested in advance.
• Parents are encouraged to bring their own formula, breast milk, or baby food, as onboard options are limited.
