Travelling with children presents a unique set of considerations compared to flying solo. From navigating airport security and managing extra baggage to ensuring their comfort and entertainment during the journey, a trip with kids can be a more complex and stressful experience. 

Parents naturally wonder if a passport is necessary for their child's travel. However, the answer depends entirely on the trip's details, so always research travel requirements to avoid last-minute complications.

To help you avoid any hiccups due to documentation issues, this guide will clarify the identification requirements for children, both for international travel and for domestic travel within other countries.

Do kids need a passport when flying internationally?

International travel with an adult

When it comes to international travel with kids, a valid travel passport is an absolute must. Unlike domestic travel, where the rules may be more lenient, international travel requires strict adherence to passport requirements and documentation. This is crucial to ensure smooth passage across international borders.

Singaporean parents or guardians must ensure their children have a valid Singapore passport. This means checking the passport's expiration date well in advance of any planned travel, as many countries require at least six months of passport validity. Additionally, they should ensure the passport is in good condition, free from damage or alterations, as this could lead to travel disruptions. You can find more information on the Immigration & Checkpoints Authority (ICA) website.

Additionally, depending on the destination, a visa may also be required. Always check the specific requirements for entry into the country you plan to visit, as these regulations can vary significantly.

For infants, specific regulations often apply, such as age restrictions and adult accompaniment requirements. It's crucial to contact the airline directly for assistance with bookings involving infants, particularly in special cases like flying with newborns or when an infant requires a separate seat. Some airlines may also have specific requirements for car seats or seating arrangements when travelling with more than one infant.

Furthermore, a Child Travel Consent Letter may be necessary, especially if a child is travelling with only one parent or guardian or with someone who isn’t their parent or guardian. This legal letter demonstrates that the accompanying adult has the necessary permission to travel with the child.

International travel as an unaccompanied minor

If your child is under the age of five, it's essential to note that airlines generally prohibit them from traveling unaccompanied due to safety and logistical concerns. However, certain airlines offer an Unaccompanied Minor Handling Service, which is often mandatory for minors traveling alone. This service ensures that a designated airline staff member will escort your child throughout their journey, from check-in to arrival, providing supervision and assistance along the way.

Additionally, airlines may require you to drop off the child to show identification. Some airlines may also ask for a notarised letter of consent from the kid's parents or legal guardians, allowing the child to fly alone.

Do kids need a passport for domestic flights within other countries?

Domestic travel with an adult

For Singaporean families traveling abroad, "domestic travel" refers to flights within the country you're visiting. For example, if you're travelling from Singapore to Malaysia and then taking a flight from Kuala Lumpur to Johor Bahru, the Kuala Lumpur to Johor Bahru flight is considered a domestic flight within Malaysia.

Passport requirements for children on such domestic flights vary by country. Some countries may not require children to have a passport for domestic travel, while others might. As such, it's crucial to check the specific identification requirements of the country where the domestic flight will take place. 

Airlines may also have their own identification requirements for child passengers, even if the country doesn't mandate a passport. Therefore, it’s always recommended to carry some form of identification for your child, such as a birth certificate, even for domestic flights outside of Singapore.

Domestic travel as an unaccompanied minor

When children travel domestically within countries other than their own, documentation requirements, especially for unaccompanied minors, can vary. While kids often need a travel passport, there may be additional requirements. So, confirm with the airline and the relevant embassy regarding specific documentation, such as a letter of consent, that may be needed for unaccompanied minors on domestic flights. If there are connecting flights, it’s important to check the transit requirements as well.

Prepare all the ID requirements for your kids

When travelling with children, it's essential to be well-prepared with the necessary identification. While domestic flights within a country might have more relaxed requirements, international travel demands strict adherence to passport regulations. 

Remember that even for domestic travel outside of Singapore, such as a flight within Malaysia, identification for your child may still be necessary. To avoid any travel disruptions, always confirm the specific identification and documentation requirements for both international and domestic travel in your destination countries.
