How to add lap infant to United booking after purchase?

Traveling with an infant can be challenging, especially when you’ve already booked a United Airlines flight and realize you need to add your lap infant. Fortunately, United Airlines allows passengers to add infants to existing bookings, but it requires careful navigation of their policies and procedures. This guide provides a comprehensive, step-by-step approach for adding a lap infant after purchasing your ticket, offering practical advice and actionable tips to ensure a smooth travel experience.

United Airlines Lap Infant Policy

Before you attempt to add a lap infant, it’s essential to understand what United Airlines allows:

Eligibility Criteria

  • Age Limit: Lap infants are defined as children under two years of age at the time of travel. Once the child turns two, a separate seat must be purchased.

  • Travel Requirements: Lap infants must sit on an adult’s lap during the flight and are not provided with their own seat unless you purchase one.

  • Documentation Needed: Passengers must provide the infant’s full legal name and date of birth. A birth certificate or passport may be required, depending on the travel destination.

Fare Rules

  • Domestic Flights: Usually, a lap infant travels for free on domestic United flights, though taxes and fees may apply.

  • International Flights: International flights typically require payment of a percentage of the adult fare, usually around 10% of the ticket cost, plus applicable taxes and fees.

Step-by-Step Guide to Adding a Lap Infant

Adding a lap infant after booking requires a clear understanding of United Airlines’ procedures. Follow these steps for a hassle-free experience:

Step 1: Review Your Booking Details

  • Log in to your United Airlines account.

  • Locate the booking you wish to modify.

  • Confirm your travel dates, passenger names, and ticket type to ensure the booking is eligible for infant addition.

Step 2: Contact United Airlines

While some bookings may allow online changes, adding a lap infant typically requires direct communication with United Airlines:

  • Call the United Customer Service: United representatives are equipped to handle infant additions. Have your booking reference ready.

  • Explain Your Request Clearly: Provide the infant’s name, date of birth, and your relationship.

  • Confirm Fees: Ask about applicable charges, especially for international flights.

Step 3: Verify Required Documentation

Depending on your destination, you may need specific documents:

  • Domestic Travel: Birth certificate may suffice.

  • International Travel: Passport and visa requirements for infants must be confirmed.

Step 4: Receive Confirmation

Once the lap infant is added:

  • Check the Itinerary: Ensure the infant is listed as a passenger.

  • Review the Ticket Details: Verify the seat allocation (if any), fees, and flight information.

  • Save Documentation: Print or download a copy for travel purposes.

Tips for a Smooth Addition Process

Adding a lap infant can be straightforward if you prepare in advance. Consider these expert tips:

  • Book Early When Possible: Adding infants closer to departure may be limited by seat availability.

  • Have Infant Documentation Ready: Birth certificate or passport should be accessible for verification.

  • Understand Fee Structures: Knowing what you’ll pay can prevent surprises.

  • Use Frequent Flyer Accounts: Linking your infant to your MileagePlus account may provide additional benefits.

  • Stay Calm During Calls: Customer service representatives handle requests more efficiently when information is provided clearly.

Special Considerations for International Flights

International travel with a lap infant requires extra planning:

Passport and Visa Requirements

  • Ensure your infant has a valid passport.

  • Check visa requirements for the destination country. Some countries require infants to have separate visas.
