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?

    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. This is because nonstop flights avoid the extra fuel consumption associated with multiple takeoffs and landings. Air Canada operates modern, fuel-efficient aircraft and offers carbon offsetting programs, allowing passengers to compensate for their flight's environmental impact.

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.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

They were fast and I like how they used to entertainment system to play video about the safety.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Flight attendants had a little attitude. Food tastes no good.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

l really enjoy very much the flight was very pleasant

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

Flight itself was not bad at all. However: my checked bag (checked in Calgary) did not make it onto this flight as I found out after I landed at EWR. I still don't have it but it appears that it is on its way to me.

Flight and attendance were very good we had 2 hour delay that took the shine of it

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

My seat was covered in vomit and I will be reaching out to Air Canada
