Top tips for finding cheap flights to Colorado

  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest Colorado flight deals.
  • Several air carriers including British Airways, Delta and Icelandair offer flights to Colorado from the UK which terminate at Denver International Airport (DEN). The largest airport in the United States, DIA (as it is commonly known) is a focus airport for Southwest Airlines as well as United Airlines.
  • Delta services flights originating in Scotland that depart from Edinburgh Turnhouse Airport (EDI) destined for DIA, but there are stopovers involved in this route. Flights in conjunction with KLM will stop at Amsterdam Schiphol Airport (AMS) and either Salt Lake City Airport (SLC) or Minneapolis-St. Paul International Airport (MSP) before landing in Denver.
  • Meanwhile, flights solely with Delta from Edinburgh Turnhouse Airport will make stopovers first at New York’s JFK Airport. From there, connections to Colorado can be made via Hartsfield-Jackson Atlanta International Airport (ATL), Detroit Metropolitan Wayne County Airport (DTW) or Minneapolis-St. Paul Airport.
  • When it comes to airports in the UK capital, Austrian Airlines, Finnair and British Airways all offer direct flights to Colorado, bound for DIA, from London’s Heathrow Airport (LHR). Lufthansa also offers flights from London Heathrow with a stopover at Frankfurt am Main Airport (FRA) before continuing on to Denver.
  • If you are leaving from Manchester Airport (MAN), you can select between Icelandair and Delta, but neither offers direct flights on this route. Icelandair will first stop at Keflavik International Airport (KEF) before connecting to Denver, while flights aboard Delta will stop first at Charles de Gaulle Airport (CDG) and then at Salt Lake City Airport (SLC).

The first economy rows have remote space in the seat which eats in the seating space. The seats are also smaller compared to other airlines.

The first economy rows have remote space in the seat which eats in the seating space. The seats are also smaller compared to other airlines.

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

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

I cancelled the flights in good time but could only get a partial refund. I was not warned of this.

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.

The coffee in Premium economy and economy is terrible. That's it. Everything else is great

Very comfortable flights. Not so many new releases in terms of films.

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.

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

Pros: "The crew was amazing and took measures to make the flight Covid safe"
Cons: "The food was not the best and Twistees weren't available. Also the seats felt narrow"

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

Staff had been really impolite at the boarding area and for both ways charged high extra fees without a reason. For the check-in luggage which was measured 3.5 kg and was confirmed by the stuff to cost 40 € , 60 Euros had been purchased from our credit card. When confronted staff did call us both liars and claimed to never have announced anything. Flight back , when not wanting to press a backpack in a measuring metal instead of hand measuring , staff got angry that one did not follow her order, which was than escalated by the team. Although carrying a baby anyways staff did not offer any help in the unreasonable process and than charged again extra money. Cabine crew has been friendly but this experience LL lead to not booking easy jet at all in the future. Check in process in Edinburgh anyways chaotic,to the family check-in and disabled check-in everybody else was guided for check in process, so people just getting in between each other, not possible to monitor your own stuff.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

This was the worst flight experience I’ve had in my entire life. The flight was delayed by four hours, there was no one to ask questions of or get updates from. I had the Ryanair app which showed a later delay than the departure board in the airport, and a different gate, and there was no one who could even tell me, which was the correct gate or time. Then, when we arrived at our destination, it took an hour for the bags to come off.

Very good, everything went straight forward, boarding, during the flight, landing and all on time Well done

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Θα ήταν καλύτερα να προσφέρουν ένα μπουκάλι νερό δωρεάν και καφέ .

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Flights were on time. The crew was efficient and friendly.

Em relação a Ryanair, ter de ir ao check-in só para carimbar o cartão de embarque não foi muito fácil, são muito demorados, e atrasam a passagem do controlo de passaporte... E cheguei com 2 horas de antecedência

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

The boarding to Gatwick was a breeze but the boarding from Gatwick was a nightmare. The onboard service to Gatwick had a lot to be desired but the onboard sevice from Gatwick was amazing ! Very nice,friendly and funny ! Would I recommend BA to anyone.? ! Yes I would!

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

It was a flight operated by Aer Linus for BA and the plane and crew were very good but the food selection was average.

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.
