When travelling with children, rule number one is to always give yourself more time than you think you'll need at the airport for check-in and security screening. All carry-on baggage including your kids' bags will need to go through the x-ray machine including diaper bags, blankets and toys. Although there is a general restriction against liquids and gels limiting them to 100ml, baby formula and food, breast milk, and juice are all exempt in reasonable quantities exceeding the 100ml, but be sure to declare these items to the security officer at the checkpoint.
Your Flight Centre consultant can find out whether a meal is provided and what inflight features are available such as movies and television so you can plan accordingly. Keep in mind when booking your flight that the most discounted tickets usually have the most restrictions with respect to cabin baggage and weight limits. Many flights now offer the option of checking in online up to 24 hours in advance which means getting your seat assignments and saving time once you arrive at the airport. If you're flying economy with a baby, try to book a bulkhead seat as many airlines provide a bassinet which can be attached to the wall in front.
Many parents flying with children under the age of two years old assume their kids fly free if they hold them in their lap. That is true if you're flying within Canada but the rules are different depending on your destination. When flying to the United States or Mexico, you will be charged the taxes. When flying internationally, you will generally be charged at least ten percent of the full fare.
Before you book any international travel that includes a child, make sure you contact the embassy or consulate of all countries the child will be visiting to find out about entry requirements. Whether travelling alone or with an adult each child, regardless of age, must have a valid passport and may also require supporting documentation. This could include a birth certificate showing the names of both parents and any legal documents pertaining to custody. If the child is travelling with one parent, a consent letter authorizing travel must be signed and dated by the other parent. If the child is travelling alone or without either parent, a consent letter authorizing travel must be signed and dated by both parents and if one of the parents is deceased, a death certificate may be required.
