Try this too. You can punch in your flight number to see if the departure is onetime or not. You can also track where the plane is prior to departure. Example; if you're departing from Toronto you can find out if the plane carrying you down has been delayed at another airport. You can now adjust your schedule accordingly. If you have a loved one come down, your track the flights progress right up until it lands at MBJ.

The app is a little hard to figure out but once you get the hang of it, it's a remarkable tool.
