Flight times can also vary a bunch depending on what day you’d like to leave. It can also affect whether or not you can get a direct flight depending on what airline you’re flying with. You may want to leave early in the morning so you get half of your arrival day in the park. Depending on how far you are from the airport you may want to leave in the afternoon so that you have the morning to get to the airport and navigate the weather. Keep in mind… if you’re flying from the United States, but live in Canada, you will need to leave yourself time for the border crossing. The bonus is you will then be taking a domestic flight and won’t have to do customs when you land and you only need to arrive 2 hours ahead for a domestic flight
Picking the right flight time is especially important if you are flying with young children. This factor alone often decides what kind of flight you have. (read more about this in my Flying with Children post, coming soon)
