• Newborns (0-7 days old): As per united airlines infant policy the airline highly discourages travel with babies who are less than 7 days old because of the health hazards such as altitude changes on the infants whose lungs and ears have not developed well.
• Lap Infants (8 days to under 2 years): Babies aged 8 days to the second birthday anniversary can be brought on board as a lap infant (1 lap infant per adult). Seat not needed, but international flights are 10 percent of the adult fare (taxes are paid). Booked as "infant-in-lap" in reservation. Mistakes happen when entering names for a new baby?s first flight. If you realize the name on the ticket doesn't match the birth certificate, our Name Change policy page explains how to fix it.
• Ticketed Children (2 years and older): Customers who are 2 years old or older, and are seated in their own seat, will incur full adult ticket costs. There are no exceptions; United is very strict when it comes to check-in.

These age guidelines can guide parents to make a good decision to ensure that the travel experience with their small ones is comfortable and safe.

United Airlines Stroller Policy

United Airlines has family-friendly stroller policy that focus on convenience of the parent travelling with the baby. Strollers are usually carried free of charge, on top of your regular baggage, and it is easier to move around the airports with small children. These regulations are applicable both in local and international flights.

Stroller Check-In Rules

United is permitting one stroller per child, and it is carried gate-checked and no additional charges are paid to the baggage limit. The main stroller check-in guidelines which one must remember are as follows:

• On top of the normal baggage allowance, United Airlines stroller policy allows one stroller (or folding wagon) to be checked free per child.
• The strollers can be checked at the ticket counter or parents can use gate-checking at the boarding stage and the latter is more convenient in terms of navigation in the airport.
• Strollers that are collapsible are eligible to be gate-checked free of charge. Non-collapsible strollers however are meant as baggage and are subject to a 62 inch linear space and this can incur oversize charges.
• One stroller and one car seat per child are also free, and any other extra will be charged as a regular baggage.
• It is important to note that the airline is not responsible to damages of checked strollers and therefore parents are advised to place them in protective bags to enhance safety.

At the Airport

Strollers can make life very easy in terms of shorter walks between the curb and the gate among others. Here's what you need to know:

• Gate-Checking Process: Use your stroller until you are at your jet bridge where you will have to release it to clear it at the gate. You are able to pick it up at the baggage claim or the entrance of your destination.
• Security Screening: When passing through the security fold your stroller and screen the stroller in the bins. TSA PreCheck will provide quick processing to families.
• Boarding Perk: When you have a child who is below 2 years, you can avail of family boarding so that you can comfortably settle after checking in your stroller at the gate.
• International Tip: Remember that there are countries where they may ask you to disassemble your stroller. Make sure to read the specifications of your destination with the help of United Airlines app.

United Airlines Infant Fare & Cost Breakdown

The United Airlines have managed to offer the service of carrying infants below the age of two years as lap children without charging on local flights between the U.S. but the international flights normally charge. The fare depends on the destination; in most instances, the lap infants are quoted 10 percent of the adult fare inclusive of taxes in international flights. An elaborate cost break down is then given in table form according to the general policies.

Note: Fees mentioned above are subject to change at the time of booking.

United Airlines Car Seat Policy

United Airlines has a simple car seat policy that complies with the FAA standards to have approved car seats to ensure improved infant safety on board. They may be used on purchased seats (not laps), free as a gate-check, or a baggage.

Car Seat Requirements

As per united airlines car seat policy, CAR seats should be approved by FAA, and that is indicated by red or orange label: This restraint is certified to be used in motor vehicles and aircraft, and it should fit between 16-inch economy seat widths. Booster, harnesses, and non-approved devices are not allowed and lap babies who are not in seats are required to check car seats at the gate or counter. There is no additional carry on allowance unless the child is having a paid seat.

Rear-Facing and Forward-Facing Seats

United has allowed both rear-facing and forward-facing car seats, which is similar to car safety best practices with infants and toddlers.

Rear-Facing Seats

They are the best protection of the head and neck of babies less than two years old. Their installation requires the aircraft seatbelt across the seat (not the child) and is required to face the seatback. Most of the models are compatible with aircraft that have a Boeing 737 or Airbus A320 body, although bulkhead or exits may have size limitations.

Forward-Facing Seats

These harnesses are suitable in older toddlers (usually 20+ pounds), are forward-fitting as in a car. Fastening them is the same way with the lap belt of the plane. Some narrower seats on newer United planes may constrain wider models; note that some of their slim seats may be measured ahead through the United seat maps.

United Airlines Bassinet Policy

On some long international flights, United Airlines also offers bassinets as a free service to lap babies and they offer a safe on board crib instead of holding a baby the entire way to the destination. These are bulkhead mounted bassinets, which are more comfortable when traveling. They are however scarce and therefore it is better to order one at an early age since there are no assurances of availability.

Bassinet Eligibility

The united airlines bassinet are also not guaranteed and have to be requested beforehand by the parents at booking. The baby has to weigh 22 pounds (10 kg) or less and be no more than 29 inches (74 cm) in length and should fit into the bassinet at least 29x11 inch. Bassinets are not allowed when the seatbelt indicator is on during taxi, takeoff, landing, or turbulence, or in unaccompanied minors, or other fare classes such as United First.

Aircraft with Bassinet Options

Bassinets can only fit certain wide-body aircrafts on international flights; and these are the Boeing 757, 767, 777, and 787 models. These are provided in United Polaris business class and United Economy on most Polaris configurations, and have fixed bassinets. Always confirm your type of aircraft through the seat maps of United because not all variants or routes can accommodate the aircrafts.

United Airlines Infant Baggage Allowance

United Airlines adds liberal baggage allowances to infants and there is a differentiation between lap infants (under 2) and infants with seats to carry family necessities with no additional charges. Infants of Lap are only entitled to baby-related allowance whereas ticketed infants are entitled to full standard baggage privileges. In both, there is no charge on gate-checking strollers or car seats.

Carry-On Allowance

Lap babies have their own space to use on their necessities that are in excess of what the adult can carry.

• A diaper bag (of a reasonable size, say 22x14x9 inches) is a personal item, which is included free with your carry-on.
• There is no designated carry-on bag that is to bring lap infants, and nursing pillows or small blankets can be placed under the seat.
• Infants with tickets: Full adult carry-on (one bag + personal item) will be used.

Checked Baggage

The amount on the checked allowances depends on the route and the infants of the flight, and is practical-based.

• Lap Infants (Domestic): There are no specific bags that are dedicated to infants, use adult allowance. Stroller/car seat gate-checked free (not a part of limits).
• Lap Infants (International): 1 bag, as an adult (e.g., 50lbs/62 linear inches); and free gate-check baggage.
• Ticketed Infants: Full adult checked baggage (1-2 bags normally free with fare).

TSA and Security With an Infant

Passing through the TSA security with an infant is an easy journey that supports the family and does not interfere with the safety levels. Parents must come early, provide officers with the needs of their infant in advance, and anticipate the screening of such items as strollers, carriers, and liquids, such as formula or breast milk.

Screening Infants and Toddlers

Children under 12 and infants are allowed to wear shoes, light jackets and head wear during screening and to pass through the walk through metal detector by a parent or guardian. Strollers, car seats, baby carriers, and diaper bags are also to be screened by X-ray or be physically/visually inspected, babies being taken off them first. Officers are cautious with the items and can provide alternative procedures such as pat-downs when necessary, which is done with a primary goal of family cohesion.

Liquids and Infant Essentials

Baby and breast milk, juice, food are also allowed but in a reasonable amount that is more than the standard of 3.4-ounce but should be reported to undergo further screening including separate X-ray/test. Ask to have hand inspections done in case X-rays are not needed so as to avoid having to open the containers, and put toys or contents of a diaper bag in the bin so that they can be inspected. TSA Cares helpline provides pre-travel assistance to families having special needs.

Tips for Smooth Security

Select family lines where you can, and take advantage of such TSA PreChecks as keeping liquids in bags where applicable. Free car seat and gate-check strollers, post-screening, and open interaction with officers to get help.

United Infant Policy on International Flights

Baggage and Gear Allowances

Lap infants are provided with one free bag of up to 50 lbs (23 kg, 62 linear inches) and a stroller or car seat on international flights. Car seats, diaper bags and strollers are allowed in either carry-on or gate-checked at no fee. Bassinets are offered on some wide-body aircrafts, by request.
