United Airlines Car Seats Policy

United requires FAA-approved car seats and mandates window placement on single-aisle aircraft. Polaris Business on 767, 777, and 787 aircraft cannot accommodate car seats due to angled seats and airbag seatbelts. If you buy a separate seat for your infant, a car seat is required. One car seat per child can be gate-checked free.
