I found it easier to purchase your air tickets than from others. Hope you would keep it up, to encourage potential passengers like me to depend on purchase of tickets in the near future. Long transits for over 8 hrs are not addressed in your trip planning that bothers passengers.
Could you please offer me the cheapest itinerary for a return ticket (YUL-DAC), moving out on/around 1 Nov 19 & return on/around 24 Apr 20? It should avoid transits through the US.
