I only wished they had tv monitors. The flight and the crew were excellent!

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.

FAQs - booking Colorado flights

  • What are common layovers for a flight from Toronto to Colorado?

    Flights from Toronto to Colorado—specifically to Denver International Airport (DEN), which is the main airport serving the state—often include layovers at major U.S. hubs. Common stopover airports could be Chicago O'Hare International Airport (ORD), Dallas/Fort Worth International Airport (DFW), or Minneapolis−Saint Paul International Airport (MSP), depending on the airline and route chosen.

  • Which airport should I fly into if I'm visiting Colorado?

    For most travelers, Denver International Airport (DEN) is the primary gateway to Colorado, offering the most comprehensive access to the state, including to the Rocky Mountains and ski resorts. If you're visiting cities like Colorado Springs or the southern parts of the state, you might consider flying into Colorado Springs Airport (COS).

  • Do I need a visa to fly from Toronto to Colorado?

    Canadian citizens do not require visas to enter the United States for short visits, such as tourism, business, or while in transit, for up to 90 days. However, you will need to provide a valid passport. It's advisable to also have proof of your ESTA (Electronic System for Travel Authorization) approval if you're traveling under the Visa Waiver Program. For non-Canadian citizens, visa requirements will depend on your nationality and the reason for your visit.

  • How can I make my flight from Toronto to Colorado more sustainable?

Top tips for finding cheap flights to Colorado

  • Toronto travelers have the benefit of access to three primary airports: Toronto Pearson International Airport (YYZ), Billy Bishop Toronto Island Airport (YTZ), and Region of Waterloo International Airport (YKF). Toronto Pearson International Airport (YYZ) sees the most international flights, including those to Colorado, but there's potential for deals departing from YTZ or YKF on occasion.
  • Colorado, known for its ski resorts and scenic landscapes, offers several airport options. Denver International Airport (DEN) is the major hub, but if you're heading to popular ski destinations like Aspen, Vail, or Colorado Springs, there are local airports like Aspen-Pitkin County Airport (ASE) or Colorado Springs Airport (COS), respectively. Your final destination in Colorado should determine your ideal airport.
  • Familiarize yourself with the baggage policies of the airlines you're considering. Major carriers like Air Canada, United Airlines, or Delta might have different carry-on and checked-luggage allowances, especially when traversing international borders. A brief check of your airline's website or a quick call to customer service can save you unexpected fees or hassles.
  • Long flights can sometimes take a toll, especially when crossing multiple time zones. After securing your ticket, watch out for promotional emails from your airline. It might offer you a chance to upgrade to premium cabins at a fraction of the original cost, allowing you to enjoy perks like more legroom, superior meals, and a generally enhanced flying experience.
  • For those flying from Toronto to Colorado, airlines like Air Canada often provide special amenities to enhance the in-flight experience, especially on the longer routes. On flights from Toronto Pearson International Airport (YYZ) to destinations like Denver International Airport (DEN) in Colorado, Air Canada offers amenities such as complimentary headphones and blankets, ensuring a comfortable journey.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

My plane was cancelled and had to be rebook for the evening was not happy.

The flight was cancelled and we had to rebook on Porter to make our cruise the next day. Air Canada has not compensated. We won’t be flying with them again. This is the second time this has happened. Also the return flight was delayed 2 hours who knows why.

Separated me and my wife and wife’s sister in far apart different seats even though I booked them all together. Just scams after scams to make us pay more. Worst airline

If you want your flight to get delayed constantly for 13+ hours and given a 10 dollar food voucher the. I would say take air canada. Worst experience ever.
