Flying with a baby or toddler can feel overwhelming—especially if you’re a grandparent helping out with travel. Between bottles, strollers, and diaper bags, the last thing you need is confusion about airline rules. So, what is United Airlines’ infant flight policy, and how does it work?
This guide breaks it down in plain, simple language, with helpful tips for seniors. And if you’re ever unsure, you can call United directly at 877-297-0699 to confirm details before your trip.
United defines an “infant” as a child under 2 years old. The main rules are:
Infants under 2 may travel as “lap infants” on domestic flights, without a separate ticket.
Parents or guardians can also choose to purchase a seat and use an FAA-approved car seat for added safety.
Once a child turns 2, they must have their own seat and ticket.
👉 Quick tip: United allows one lap infant per adult traveler.
Domestic flights: Lap infants can fly free. They don’t need a separate ticket, but must be added to the reservation.
International flights: Even lap infants may require payment of taxes and fees, or a small percentage of the adult fare.
Onboard requirement: The infant must stay on the adult’s lap during the flight.
👵 Example: A grandmother flying with her 1-year-old granddaughter from Chicago to Dallas saved hundreds by using the lap infant option.
Although lap infants are allowed, many grandparents or parents prefer buying an extra seat for the baby. Reasons include:
Safety: FAA recommends infants under 2 ride in an approved car seat for the flight.
Comfort: A car seat gives babies their own space, which can be helpful on longer flights.
Convenience: Easier for grandparents traveling alone with a baby to have hands free.
✈️ Note: United allows FAA-approved car seats that fit within their seat dimensions—best to check when booking or by calling 877-297-0699.
Domestic flights: Lap infants travel free.
International flights: Lap infants may require taxes, fees, or a small percentage of the adult fare.
Buying a seat for a baby: Cost follows normal child fare rules.
💡 Always confirm exact costs by calling 877-297-0699, as international infant fees can vary depending on destination.
Traveling with a baby is a challenge, but these tips make it easier for seniors:
Request pre-boarding for extra time to settle in.
Choose bulkhead seats for more legroom and space for baby supplies.
Bring essentials—snacks, bottles, diapers, and comfort items.
Use strollers and car seats that are lightweight and meet United’s size guidelines.
Pack smart—keep baby supplies in an easy-to-reach bag.
👴 Example: A senior couple traveling with twin grandsons said pre-boarding gave them the breathing room they needed to get organized before other passengers boarded.
Here’s the step-by-step process:
Book your own ticket online or by phone.
Add your infant as a lap child or purchase a separate seat.
Pay applicable fees for international travel, if required.
Call 877-297-0699 to confirm details or check car seat approval.
Arrive early at the airport for smoother check-in.
United’s infant flight policy is straightforward: children under 2 can fly free as lap infants on domestic flights, while international travel may include taxes and fees. For added safety and comfort, you may also choose to purchase a separate seat and use a car seat.
With a little planning—and a quick call to 877-297-0699 for confirmation—you can enjoy a smoother, less stressful trip with your little one.
