I booked the flights for our family's first big European adventure a few weeks ago - nonstop from Ottawa to London, and then Paris - Montreal - Ottawa on the way home.
In the last two days I've received two notifications from Air Canada that the Montreal - Ottawa leg was changing. The first reduced connection time from two hours to 90 minutes, and the second one reduced the connection time to 75 minutes. This seems to me, a somewhat inexperienced international air traveler who will be hauling three kids in tow, to be cutting things a little close. There are a few later flights that day from Montreal to Ottawa, and it's the home leg of the journey, so I'm not overly concerned, but I did book those particular flights with the intention of a decent buffer to make the connecting flight.
So my question is - how short is too short for connections on the homeward leg of an overseas flight? There are two other flights listed on this particular day to get us back home, but who knows how full they might be for travel in July. Any thoughts?
