Does Flydubai Offer Child Discounts?

No, unless it's for an infant sharing a parent's seat. If they offered child discounts, adult fares would have to rise to compensate.

However, there are some differences in taxes for children, so if your child is more than 2 years old and less than 11 (for the whole duration of their journey) you should book them as a child. The fare will be the same as an adult fare, but the taxes might be lower.
