Flight from Toronto Pearson Airport to Denver

Make sure to check the airline delay flights rate and if you have important commitments choose another airline.

JoshuaFlew with Air CanadaYYZ-DENApr 2024

Toronto's customs was one of the faster experiences I've had. They opened four more lanes to expedite the process when the lane got too long, to ensure we would all get through within around 15 minutes. The public transportation within the city is also top notch, in my opinion.
