  • 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).

Excellent 10.0

Pros: This is how my trip started that day. Missed my checkin window by 10 mins do to waiting in traffic for 45 mins, because of wreck. Got to the ticket counter at 8:35 and my flight my was set to take of at 9:30. There wear others in the same boat as me, we where all flying with American. I will Never ever fly with American again! The Lady was so rude then she said we were disgrutle when we ask to speak to a manger about trying to board even though or flight didnt leave until 9:30. Not Military Friendly at all. So I ran down to Lufthansa and talk with a guy at the ticket counter that was understanding of the sistuation, he told me what to do once a Book my trip through Kayak he checked me in and got me right to the front and on the plane for the next flight that left 2 hours after my missed flight. I book my trip and got through Tsa all before my flight with american even took off. When I boared the plane the cabin crew was very helpful and laughing and joking with the passagners their smiles brighten my day and made me feel at easy. I was stressed out about missing my flight with American Airlines and that lady at the ticket counter that when on got my flight with Lufthanse I felt like they were my friends and that I have been flying with them before. I will always use Lufthansa when fliying back home back to the states! Thank you to flight crew and men and women at the ticket counters!!

Cons: If I could change one thing it would be better food, or the drink protion size or just give out canned drinks. But over all the best flight I have taken in a long time!!

Because our next connection flight (ALSO THROUGH LUFTHANSA) was in 40 mins per their booking, we arrived at the gate just prior to take off to find our flight had been given away and we had “missed” that flight. As a result, we were placed on a flight 4 hours later, resulting in a dangerous attempt at reaching our hotel at 11pm. Will never fly Lufthansa again.

Additionally I'm glad the crew is fond of one another, but they were loud and distracting. They were nicer to one another than the people flying. I didn't like being barked at and being given confusing directions regarding exiting the plane. Overall I wasn't impressed and would prefer to not fly with your airline again.

Pros: nothing really. There were so many rude staff members at this airline. I saw people get yelled at by staff members. They were just trying to get information on the late flights and missed connections. It happened repeatedly. this company has the worst customer service I have seen probably ever.

Cons: They need to care about their customers and care for their customers better. They have a lot to be ashamed of.

Pros: The crew were friendly enough and willing to serve.

Cons: The seat could have been thicker and softer for greater comfort--instead, it was thin and flimsy. There should also be greater space/pitch between the rows of seats.

Okay 4.3

Pros: There was nothing really special or to write home about on this particular Lufthansa flight: it got us there safely and ahead of schedule, albeit, uncomfortably (seats were extremely thin and uncomfortable) and the pitch/distance between seat rows was extremely short & cramped..

Cons: Seats could have been more comfortable; they were extremely thin and uncomfortable--and airline could give more legroom/pitch between seats.

Okay 5.0

Cons: The passenger sitting next to me smelled REALLY bad. Like he hadn't washed himself in weeks. Other passengers around me got a whiff too and also reacted the same. I asked the main crew member from my aisle for a seat change but he came back 10 mins later saying there was nothing else available. Later when I was walking around to stretch my legs, I saw there were AT LEAST 10 seats open in the next cabin. Why lie? The entertainment system touch-screen was not working properly and the headphones kept falling out of my ear.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an and someone from our team will get back to you promptly.
