Yes, you can fly with your infant as long as he is at least 7 days old. Babies under the age of 2 must travel seated on the lap of an adult.
You can bring, free of charge, two baby equipment items (a stroller, a car seat or a fold-away cot). Remember that you may not board the cabin of the plane with car seats, strollers, or cots. The items must be tagged at the check-in desk.
