Some children may need a flight assessment before flying. Although aeroplane cabins are pressurised, the air has less oxygen than on the ground. This lower oxygen level can affect some children with heart conditions.

A flight assessment checks:

• whether your child needs oxygen during the flight
• how much oxygen your child may need

Specialist staff in a respiratory unit carry out the assessment, which usually takes about 20 minutes. During the test, your child sits in a sealed room with air pressure similar to flying. Your child wears a small probe on their finger to check oxygen levels. This helps to see how their body responds to lower oxygen. After the assessment, your child’s doctor will decide if it is safe for them to fly. If needed, the doctor can also complete travel clearance and insurance forms. Allow enough time before your trip for the doctors to do this.

Airlines have different rules for travelling with home oxygen therapy equipment. Contact the airline before booking your tickets to get information, including:

• whether your child’s specific equipment is approved to be onboard the flight
• if you need pre-approval for your child's equipment
• whether you need to purchase oxygen canisters directly from the airline
• if there is an in-flight power supply available

Most airlines will have their medical clearance form available to download from their website. Print and have the form completed by your child's doctor well before your travel date. The airline might not allow your child to board the flight without an approved form.

Travel insurance is important for both domestic and international flights. In case of emergency, you should check whether the country you are flying to has a shared health care arrangement with Australia.
