Flights from Toronto to Colorado: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Toronto to Colorado 
F.Flew with United AirlinesYYZ-DENAug 2024
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?

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).

    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.

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.

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

Excellent service despite turbulence during the flight. Flight attendants were remarkable!

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

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.

The seats are totally uncomfortable making the flight less than pleasant. The cookies & pretzels were terrible!!!

Not the greatest experience everything was pretty mediocre. My seat was by the washroom in the aisle and was not located well as everyone past each other people were right in my seat and space.

The small prop plane was crowded and the overhead luggage storage is a smaller than on the jets. Other than that, the crew was good, the flight was on time and the landing was smooth.

There was a medical emergency that the crew handled very well. There was no “entertainment” of any sort-no movie/music/whatever. Food was typical of airlines: mediocre.

Late departure, so I missed connection in Detroit. But Delta gave me a great hotel & breakfast. Just sorry I could not get anything from my checked baggage.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

No space in overhead bin, one cookie, 2 oz of juice - is not customer service.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

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.
