Ottawa to Montreal before flight to Denmark

Once Graeme and his brother, Alan, decided to fly to Denmark on a flight out of Montreal, the question then became how to get to Montreal from Ottawa. There are plenty of options. Although not always the case, from past experience the most expensive option is usually to get a connecting flight from Ottawa International Airport. Usually, the cost of this option is a determining factor but, since travelers need to be at the airport early to get through security screening, etc., time can also become a factor especially since airlines won’t book connecting flights unless there is adequate time (big buffer) at the Montreal end to transfer both luggage and passengers to the international flight.Winter weather also plays into the equation but in the summer is not normally a determining factor.
