Lifestyle & Parenting

Flying with your kids for the first time? Exciting, isn’t it? You can’t wait to watch their reactions the first time they’ll ride an airplane. But flying with them needs more planning than an actual adult travel. And the first question that pops into your mind is, what do minors need to fly?

Well, the requirements can differ depending on the age of your child, where they’re going, and whether they’re flying with a parent or guardian. 

This guide summarizes some of the most common airline policies. These policies may differ, however, so you should check with the carrier that you plan to use for a description of its rules and services and any additional charges that may apply.

And if you’re travelling with your baby, don’t forget to bring a stroller for newborn. With this tool, you can make your air travel much easier and without so much stress. A stroller that is lightweight and travel-friendly helps you move easily through the airport. It also keeps your kid comfortable during long walks between gates. Most airlines allow strollers to be checked at the gate, so you don’t have to sweat about it.

Standard ID Requirements for Minors on Domestic Flights

It is important that you know the requirements for minors on domestic flights. This way, you’ll be prepared at check-in and security. In the United States, the guidelines of transportation authorities and airlines vary depending on age.

Babies and Young Children (Under ~18)

  • Children under 18 usually do not need a government-issued photo ID when flying domestic flights with a parent or guardian. In most cases, TSA does not require them to present an ID at security checkpoints.
  • Airlines, however, may ask for proof of age for lap infants, usually under 2 years old. You can show the airport security their birth certificate or hospital record to verify their age.
  • There are carriers who may need identification if your child is travelling without you, even on domestic routes.

Passport or Other ID for Certain Circumstances

  • In the case you’re flying across states, the airline may need additional documentation. This is just to verify their age or for fare categories. It is better if you prepare your kid’s passport, state-issued ID card, or certified birth certificate to make the security checkpoints faster.
  • As always, check the policies of your airline in advance, because not all rules are the same.

Essential Travel Documents for International Family Trips

Documentation rules for minors are way stricter on international flights. Every child, regardless of age, must meet all the international entry and exit requirements. Below are the travel documents of your kid that you need to prepare.

  • Valid Passport: All minors, infants included, need to have their own passport. Many countries require at least 6 months of validity beyond the date of your return.
  • Visa (If Required): There are destinations that require children to have visas, even though the adults are visa-exempt. Just to be sure, check the rules for both destination and transit countries.
  • Parental Consent Letter: A consent letter is needed if a child is to travel with only one parent, a guardian, or another adult. The letter needs to be notarized, too.
  • Birth certificate or Proof of Relationship: This is really useful, especially if the last name of the child is different from the accompanying adult or if immigration officials request another verification.
  • Health and Vaccination Records: Certain countries may ask you to provide your child’s proof of vaccinations or even medical documentation.

When You Need a Birth Certificate for Infants and Toddlers

When you’re going to travel with your baby, you first think of the question, what do minors need to fly? One thing you need to prepare is their birth certificate. Although this document is not always necessary, there are times when authorities may request one.

  • Age Verification for Lap Infants

Airport security usually needs proof of age for children under two who are flying as lap infants. The most commonly accepted document is a certified birth certificate.

  • Domestic Flights Without Photo ID

Since babies and toddlers don’t have photo IDs with them, again, a birth certificate may be requested to verify their identity or age during check-in.

  • International Travel

Aside from a passport, a child needs to have their birth certificate, especially if they’re travelling with one parent or a guardian.

  • Name or Relationship Verification

If a child’s last name is different from the accompanying adult’s, a birth certificate can help confirm the parental relationship.

  • Unaccompanied or Guardian Travel: Airport security may need a birth certificate when a child is flying solo, flying without both parents. This is to ensure proper authorization.

Understanding the Parental Consent Form for Solo Travellers

If your child is travelling on their own, you need to prepare a parental consent form. This is to help the airlines and immigration officials confirm that your child has permission to travel. Aside from that, with a consent form, they’re protected from custody or trafficking concerns.

When a Parental Consent Form is Needed

  • A child travelling alone (unaccompanied minor)
  • A minor flying with only one parent
  • A child travelling with a guardian, relative, or school group
  • Most international flights, even if the airline does not directly request it

The consent form should include the following details:

  • The child’s full name and date of birth
  • Travel dates, destinations, and flight details
  • Full names and contact information of the non-travelling parent (s)
  • A clear statement granting permission for the child to travel
  • Copies of the parent’s or guardian’s government-issued ID
  • Notarization, which is strongly recommended and sometimes required

There is a possibility that airlines and border officials deny the boarding or entry of the child if there is not enough proper consent documentation. Even on domestic flights, a signed consent form can prevent delays or questions at check-in.

To make sure your child will have a smooth travel, prepare the consent form in advance. Double-check the details, if you have to. It is also better if you keep both printed and digital copies easily accessible throughout the whole trip.

Documentation Needed When Travelling With Only One Parent

It is important that you really understand what minors need to fly when your child is flying with only one parent. Airline security may need additional documentation to confirm the travel permission of your child.

Essential Documents to Carry

  • Valid passport (for international travel)
  • Parental consent letter
  • Birth certificate or proof of relationship
  • Copy of the non-travelling parent’s ID

Additional Documents That May Be Needed

  • Custody or court documents
  • Death certificate (if applicable)
  • Divorce or separation agreements

Border agents are trained to prevent child abduction and custody disputes. Make the proper documents readily available to make the check-in, security screening, and immigration clearance much faster. 

Navigating the Real ID Impact for Teens and Young Adults

The rules for REAL ID are mainly for travellers who are 18 and older. However, it is better that you understand how they apply to teens, so you’ll not end confuse at the airport.

Who Needs a REAL ID

  • Travellers under 18: Minors do not need a REAL ID in domestic flights when travelling with a companion.
  • Age 18 and over: Young adults need to present a REAL ID-compliant driver’s license or state ID. They can also present alternative documents, like a passport, for domestic flights.

What Teens Can Use Instead

  • A valid passport works for both domestic and international flights. It is also a good option for teens approaching adulthood.
  • There are airlines that accept school IDs for identification. But, they cannot be substitutes for REAL ID once the traveller turns 18.

Teens who turn 18 shortly before a trip may suddenly need different identification than they did on previous flights. If they don’t have the proper ID, they could face delays or worse, they may not be able to pass the security. 

It is better for parents to plan for teens nearing adulthood. Make their child apply for a REAL ID-compliant card or passport before going to travel.

Special Requirements for Children Flying as Unaccompanied Minors

It is more important that you understand what minors need to fly when your child is flying alone. Many of the airlines have strict rules. This is to ensure their safety and supervision of unaccompanied minors. As mentioned earlier, these rules can vary depending on the carrier.

Age Rules for Unaccompanied Minors

  • Airlines usually require unaccompanied minor services for children ages 5-14.
  • Teens 15-17 may be allowed to fly alone without mandatory supervision. Although optional services are still available for them.
  • Children under 5 are generally not permitted to fly alone.

Required Documentation

  • Unaccompanied minor form
  • Valid identification
  • Parental consent letter
  • Government-issued ID for guardians

Most airlines have fees for unaccompanied minor service each way. The child will be escorted through the airport, assisted during connections, and released only to an approved adult at the destination. 

Keeping Your Child’s Travel Documents Organized and Secure

After knowing what minors need to fly, the next step you need to do is keep them organized and secured. It can be really stressful if one document is missing or misplaced. So, make sure they packed and well-organized.

  • Use a dedicated folder or zippered pouch for each child
  • Keep all documents together in your carry-on, not checked luggage
  • It is better if you make photocopies and save digital copies on your phone
  • When possible, use RFID-blocking holders
  • Keep documents easily accessible throughout airport travel
