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?

    To make your flight from Toronto to Colorado more sustainable, consider flying with an airline like Air Canada, which is recognized for its commitment to sustainability. Booking a nonstop flight from Toronto Pearson International Airport (YYZ) to Denver International Airport (DEN) with Air Canada can help reduce your carbon footprint.

Top tips for finding cheap flights to Colorado

  • Morning departure is around 15% cheaper than an evening flight, on average*.
  • 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.

Not very comfortable seated in the back plane due to turbulence

Not very comfortable seated in the back plane due to turbulence

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

Ford not that great the seat not to big for leg room like other airline

On time and flight crew are always so happy to help and always smiling unlike other airlines.

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Not accommodating ground staff On board slow service Crew members not very friendly

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

The type of the food requested (Asian vegetarian) was not properly met with. They have very limited snack items that may compensate for the main meals.

The flight was ok. The person who brings tea and coffee totally forgot about us or just walked past at both meals. And special attention is given if you are Taiwanese

The quality of the food is pretty good. Thank you, EVA Air.

A wonderful new plane. Great menu. Professional service. You and your wife were completely satisfied.

Pleasant, comfortable, and entertaining. All told, ZERO issues with it. And sadly, so far the flight was WAY more comfortable than the hellhole that is "Lambug Beach Resort" at Badian Beach!

Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.

No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.

Staff’s were polite & helpful. Love to fly with Eva Air!❤️

Eva is one of the top airlines in Asia... but often are over priced. Finally found a reasonable rate.

My original flight was rescheduled & EVA did a good job rescheduling my flight & connecting flight.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Not good. Flight was purchased for my father who needed medical assistance to board and transfer due to a heart condition. No one at Hong Kong from Cathay was there to assist and he barely made the connection. When I talked to him he could barely breath and was not sure he was going to make it. Really poor service even though the ticket stated he needed a wheelchair assistance.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Not impressed with check in desk staff at Vancouver airport. Not a professional mind service and not cared or tried to help. Don’t think I would fly with them again

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

In flight entertainment system including wifi were down and passengers got tortured for the 16 hours flight without any of these. Food was spoiled as well for the first meal provided but second meal was Ok. Overall a horrible experience which was not at all expected for such a long haul flight which was expected to be THE most memorable part of my planned trip for family.

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

Cons: "The flight delay could have been announced over the speakers"

Nice smooth flight with pleasant stewards. Slept most of the flight, they could have slowly turned on the lights to make it more pleasant. Otherwise a good trip.

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Crew was rude.didn’t even say hi or welcome to board

Nothing special. Unacceptable wait for baggage on arriving in Calgary

Departure delay on a late night flight. Made us even later. Tired but got home.

Westjet forced me to put my carry-on baggage in check-in probably because I was assigned seat 23A (the last row seat), which had no cabin space, which is unfair. I wanted to carry on my luggage so that I don't have to wait at the airport for my luggage. Also, because there was no cabin space, I was forced to keep my laptop bag under the seat, which I didn't want to as I was carrying 2 laptops and charger. The airline should basically tell people that if you are assigned a last row seat, then you are not allowed a cabin baggage or a personal item.

Easy processing, flight time was quick and staff was professional and kind.

It was delayed by two ours very full no room to move

They seem to have squeezed out a little more legroom in these planes! It was very nice to not have to fold in half to fit in the seats!

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.

Limited snack options cause the snack vendor was on strike

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

I didn’t like the fact that all the customs officers went to lunch so I was in line for 90 minutes due to where the staff directed me. We were told three very different reasons for why the plane was delayed. It was a crowded plane with difficult storage situations for the Carry On bags. The Air Canada airline staff were all very good and professional. I was so disappointed in my cheese and fruit box as the cheese had molded and the fruit wasn’t fresh so I couldn’t eat the majority of the food. This was the last meal I could find as the restaurants had closed when I got in to my destination. I think you could work on improving the food quality.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

The staff were so kind and helpful. We flew back from NY with another airline and it was horrible. We will always stick with Air Canada as everything was far better!
