Make sure to check the airline delay flights rate and if you have important commitments choose another airline.
JoshuaFlew with Air Canada-Apr 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.

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.

Very efficient. Economy is what economy is. Wish it had been direct. Excellent setup in Newark for commuters and access to charging stations and wifi Flight could’ve had free wifi

My flight was cancelled and United Airlines could not rebook or help. My whole trip was then cancelled and I could not go to the funeral I needed to get to.

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

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

United airlines was top for my last trip in every way

Bad, they delayed my flight, lost my connection flight had to stay overnight for the next flight and missed a lot of important meetings. 1 day totally lost!

Boarding was quick and efficient which was nice and it was a nice treat to have a screen to watch a show for the quick flight!

airport arrival to Denver direction to where to go was not clearvfor Me.

Staff never asked passengers to bring their seat backs forward during landing. Was hoping to get a little relief from the passenger in front of me (I have long legs that I cannot stow in the overhead). Otherwise the flight was very pleasant.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

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

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

The flight attendants that assisted me were exceptionally nice, kind and helpful

Very good. But seat selection was not good. We were put on different rows. Would have been nicer to sit besides each other as a couple.

The crew and the flight was excellent. Captain kept us informed about weather and possibly of turbulence and I appreciated that! The only thing is they didn’t have tv monitors. Other than that, everything was great.

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

The boarding process in Toronto bad as they share space with domestic flights and when those domestic flights come in you are locked out behind closed doors until they are done and then its a mad rush to get your boarding gates and board. This is not so much due to Air Canada but with the GTAA, but Air Canada could use different gates especially early morning in order to prevent such travel angst.
