Flying Alone with a Toddler: The Solo Parent’s Checklist

Flying alone with a toddler is mostly about hands. This checklist covers the consent letter and documents you may need, booking the right seats, packing so everything works one-handed, getting through security and boarding, toilet trips on board and arrival.

Flying alone with a toddler is mostly about hands. You have two, and the trip seems to need five: one for the child, one for the bags, one for the passports, one for the stroller and one for the coffee you won’t get to drink. The good news is that most of the hard parts can be solved before you leave home, with the right documents, the right seats and a bag packed so everything you need is reachable with one hand. This checklist walks through a solo flight with a toddler from booking to arrival.

Before you book

Consent and documents

If you’re taking a child abroad without the other parent, check what proof you’ll need. GOV.UK says you must have the permission of everyone with parental responsibility for a child, or a court, before taking a child abroad from the UK. It says a letter from the other person with parental responsibility is usually enough, and that you might be asked for it at a UK or foreign border. The letter should include their contact details and details about the trip. GOV.UK says it also helps to carry evidence of your relationship with the child, such as a birth or adoption certificate, and a divorce or marriage certificate if your surname is different from the child’s.

Other countries have their own rules, and some ask for more. Check the official guidance of every country on your trip, and your airline’s rules.

Seats

• A seat for your toddler. Under twos can usually fly on your lap, but on your own, a seat of their own (with their car seat) gives you a free pair of arms. The US Federal Aviation Administration (FAA) says an approved child restraint is the safest place for a child under two.
• Window for the child, aisle for you, so they can’t escape into the aisle and you can get up.
• Not the exit row: children can’t sit there.
• Close to the front if you’ll be gate-checking a stroller, for a quicker exit.

Flights

• Direct if possible: every connection is another round of bags, toilets and boarding.
• Times that match your toddler’s best mood, not just the cheapest fare.
• If you must connect, allow plenty of time.

Packing for one pair of hands

• A backpack for you instead of a shoulder bag or tote, so both hands are free.
• A small backpack for your toddler with their snack, a toy and a book.
• A front pocket or a crossbody pouch for passports, boarding passes and phone.
• Check in the big case rather than wheeling a cabin case as well as a toddler.
• A lightweight stroller you can fold with one hand, or a carrier.
• Clear liquids pouch on top, and milk and baby food together, ready to hand to security.

At the airport

Check-in

Check in online, use the family check-in desk if there is one, and hand over everything you can. Many airlines carry strollers and car seats free; you can often keep the stroller until the gate.

Security

• TSA says strollers, car seats and carriers must go through the X-ray, and children must be taken out and carried through the metal detector. Children 12 and under can keep their shoes, light jackets and hats on.
• Take liquids, laptop and tablet out before you reach the belt.
• Fold the stroller last, with your toddler holding your hand or in a carrier.
• Ask for help: security staff see solo parents all the time.

At the gate

• Let your toddler run around in a quiet corner.
• Change the nappy or visit the toilet just before boarding, as the American Academy of Pediatrics suggests for babies.
• Ask about early boarding for families. It gives you time to fit a car seat and settle in.
