Flying with a baby: airline fees and regulations

How old does a baby need to be before they can fly?
This depends on the airline. Many stipulate that your baby must be at least 14 days old before they board their first flight, though some will accept 7-day-old babies. If you have a newborn, you'll usually need a medical certificate from your doctor confirming your baby is approved to fly. However, we recommend you contact the airline you’re travelling with to find out what their specific policy is.
What’s the difference between a child and an infant?
Annoyingly, there's no concrete answer for this, as different airlines have different regulations. Generally, a child under 2 years of age is classified as an infant. Between 2 and 16-years-old, they're viewed as a child (though some airlines also have a 'teen' ticket category).
It's worth noting that if your child crosses the airline's age threshold between an infant and a child while you're travelling (i.e. celebrates their second birthday), it may affect the kind of tickets you book and how you need to book them. Check with the airline for more details before booking tickets to fly with your baby.
