Find Cheap Flights from London to Denver International (LON - DEN)

Pros: Comfort of the plane, service

Cons: No business lounge in CDG before 9am

Pros: The food was okay but thats the best thing I can say.

Cons: There was someone that pooped themselves, another that threw up, and the flight attendants were so rude. They kept spraying stuff in the air and even those of us sitting, so much in fact I had an asthma attack and had to use my inhaler. When I told the attendant, she said "theres nothing I can do," and kept spraying the air with this awful spray. The flight harmful to my health, exhausting, and uncomfortable. BEWARE OF THIS AIRLINE! I would have preferred not gone on my trip then fly this airline!

Cons: Flight delays is a constant problem with this company

Pros: The crew was very cool

Cons: The food was ok

Pros: Comfortable seats (787), more-or-less on-time service.

Cons: Probably the unhappiest check-in and flight crew I've flown with. Makes me wonder what Norwegian does to its employees. Be advised that they weigh your carry-on bags, and you may be forced to check them. Basically, add $60 to your ticket price to account for round trip bag fees.

Pros: Efficient, quick, well organized

Cons: Nothing really

Pros: Flight attendants very friendly

Cons: Difficult to get water during flight. 2 hour delay sitting on the tarmac at airport.

Pros: NOTHING!!!!!!

Cons: I absolutely hate traveling on this airline and with all the hidden charges realize that they are NOT as budget as one would expect. In this day and age how can one human being pass food or beverage under your nose to the passenger sitting next to you and not have the common courtesy to inquire if you are hungry? It seems odd to serve the "haves" while the "have nots" look on in hunger, the latter group even including children. Surely the better business model and or approach would be an inclusive one. When comparing the additional costs to travel its is far cheaper to take an option whereby luggage and food are included and you are not charged ridiculous amounts for, lets face it microwave meals. The PR for this company is misleading as it does not let the consumer know that this a LOW LOW budget airline and that traditional allowances on long haul flights have been totally obliterated!!!! I have travelled with Norwegian Airlines a total of 3 return flights and have finally had enough, they are an only option at times otherwise the extra 100 dollars for another airline is a pleasure to pay.

Cons: Three hour delay in Reykjavik was needed and appropriate because of harsh/blustery winds. The passengers appreciated the absolute attention to safety in the long delay.

Pros: I’m usually easy to please but there wasn’t much to say that’s positive. Maybe the staff was helpful?

Cons: Air was out in coach so everyone was sweating in a sauna, while first class was cold and didn’t want the air any higher, major problem, needed to sleep but could get 15 min in. Worst flight I’ve ever been on, never been that uncomfortable in the air before

Pros: Clean flight on time and short route

Cons: First time I had a transatlantic flight where there were zero meals or snacks

Pros: Larger plane with more room

Cons: Boarding was a mess, no rows called; no one at the help desk.

Cons: Missed my flight by 2 minutes and couldn’t find any representatives to help me determine my options. Was left to figure it out in my own.

Pros: Nice entertainment selection

Cons: Too many snacks, food was low quality, flight was delayed with no reason given,

Pros: Loved the German touches like real silverware, good wine, and German movies with English subtitles! Also appreciated lots of liquids and never had to go searching for hydration.

Cons: Everything was great until we landed and I stood up in the aisle. A woman two rows behind opened the overhead compartment and pulled her huge backpack out, landing it right on my head! OUCH! I scolded her and she apologized, but, REALLY? Perhaps the crew needs to reiterate how dangerous this is to do! My head still hurts a little on top, almost a week later. Ugh.

Pros: Was nice and pleasurable

Cons: Nothing

Cons: Three hour delay in Reykjavik was needed and appropriate because of harsh/blustery winds. The passengers appreciated the absolute attention to safety in the long delay.

Pros: The crew

Cons: The boarding process was so chaotic at Iceland airport. Also for a 8hr flight food should be given not charged. The movie selection good have been better.

Pros: Smooth on time flight...helpful responsive crew. Loce watching movies!

Cons: Food was not great...economy seats tight especially when the person in front of you puts their seat back and are essentially sleeping on you lap. This happened to me coming and going....

Pros: Clean flight on time and short route

Cons: First time I had a transatlantic flight where there were zero meals or snacks

Pros: Nice crew. Smooth and quick ride which is perfect. No entertainment system or food so cannot comment.

Cons: Worst airport to board from (Tegel). Waited 30 minutes for luggage in frankfurt airport. Unacceptable luggage handling (may related to airport in Frankfurt).

Pros: I have never been treated so poorly by counter people in my life!

Cons: After 2 hour delay, the flight was cancelled. NO ONE helped to find another flight. After waiting in line for 2 hours, the ticket agent handed me a card and said I had to call the 800 number. The person on the phone said I had to talk to ticket agent to go standby on a flight to Munich and the ticket agent told me I had to call. I was caught in a loop and no one helped. Then when it became apparent I wasn't getting out that night I was informed that there were no hotel vouchers and I would have to find my own hotel! After searching for an hour for a hotel (all were sold out in Boston) I called a friend who lives outside of Boston. No one gave me a taxi voucher because it was not to a hotel. LUFTHANSA customer service is the WORST!!!!!!!!

Cons: I did not like the fact that the United flight I came in on was over a MILE of corridors away from the outgoing flight.

Pros: Crew was so attentive and helpful. Very courteous and friendly. Had great experience.

Cons: Head rest on Seats tilts slightly forward making long flight uncomfortable

Pros: Crew professionalism

Cons: Earphone, squashy seat, limited leg space in economy class

Cons: Had no idea we had not payed to check a bag. Could have paid online prior to boarding for 30 pounds, but because we did not know, had to pay 65 pounds in order to check a bag at the airport. I am extremely dissatisfied with this flight and with British airways in general. I wish I would have known about the baggage and I could have saved myself a LOT of money. British airway crew were rude and unhelpful. I will not be flying with them again.

Cons: I paid extra for exit row seating, but what they didn't tell me was that the flight attendant seat was facing ours, so much for leg room. The actual placement of the seats were aisle row and middle row-so neither of us had a window to look out of or wall to lean against, no overhead lighting or air vent either. Can you say "rip-off?" My husband, who is tall and broad shoulder was constantly being knocked around by the flight attendants and carts. This flight was miserable. I guess I should be thankful for the hour plus delay in departure.

Cons: Dear Sir or Madam: My two colleagues and I bought our tickets from BWI to Geneva, via London Heathrow, through Kayak as I have many times in the past. However, the Kiwi.com travel agency did not flag that the ticket from BWI to London Heathrow allowed for one piece of checked luggage, but the ticket from London Heathrow onwards to Geneva did not allow for any checked luggage. Also astonishingly, we had to pass through Customs, reclaim our checked suitcases from the baggage carousel, and check in again through Customs to board the onward flight, both coming and going through London Heathrow. In addition to the extraordinary inconvenience that we could neither transit at London Heathrow to our connecting flight without going through Customs twice and that we could not check our luggage through to our final destination, we also had to foot a higher baggage charge to allow for checking in our suitcases, now that we had arrived in London Heathrow only to discover this that our onward ticket did not cover one piece of checked luggage. Had we known that the seemingly better price posted by Kiwi.com on Kayak’s comparative offerings came at such a high price of inconvenience and additional expense for the luggage, we would have taken our business elsewhere. It was deceptive of Kiwi.com to engage in such practices, even if it disclosed these conditions in fine print (for no one would expect, nor have I ever seen previously in the hundreds of flights I have taken as a Million Miler on United), without flagging this. And similarly, it was irresponsible of Kayak.com to allow this “apples with oranges” comparison on its website. I’m making three more international trips in December, but I’m inclined not to use either Kayak.com and most certainly not Kiwi.com for future airline ticket purchases.

Cons: I did not like the fact that the United flight I came in on was over a MILE of corridors away from the outgoing flight.

Pros: Nice entertainment selection

Cons: Too many snacks, food was low quality, flight was delayed with no reason given,

Pros: Loved the German touches like real silverware, good wine, and German movies with English subtitles! Also appreciated lots of liquids and never had to go searching for hydration.

Cons: Everything was great until we landed and I stood up in the aisle. A woman two rows behind opened the overhead compartment and pulled her huge backpack out, landing it right on my head! OUCH! I scolded her and she apologized, but, REALLY? Perhaps the crew needs to reiterate how dangerous this is to do! My head still hurts a little on top, almost a week later. Ugh.

Pros: The food was good was good

Cons: The entertainment was poor the movies selection was poor

Pros: Very cheap flight

Cons: No in-flight food, just water. Plane was very small. I’m almost 7 ft tall and asked if I could swap for an exit row, no dice. So I felt like a human-accordion between two rows of seat for the entire flight. I got what I paid for. Cheap airfare= discomfort.

Pros: The flight took off and landed on time. There were also a lot of good food options on the flight that were not only edible, but also healthy

Cons: Got email night before that flight had cancelled or changed. Ended up on a flight on United. Got to my destination as scheduled.

Cons: After the 8+ hour delay, Icelandair cancelled the flight. If you have a connection, you’re out of luck with so little flight options.

Pros: Leg room, friendly crew, good choices for entertainment, nice blankets!

Cons: The flight was delayed for an hour, but the transfer in Helsinki was easy, I made it to the connect flight just in time for boarding

Pros: Great crew and service

Cons: Uncomfortable seats. Not only no space to get comfortable but the seats themselves are not comfortable. We had better constructed seats on the hopper from Edinburgh to London. It is unconscionable that long flights are so uncomfortable!

Pros: Food surprisingly good

Cons: Usual uncomfortable seating

Pros: This is a great way to travel from Helsinki to Tampere and avoid the railway and train changing.

Cons: The plane is not comfortable, but the flight is very short. It balances out.

Pros: Nothing

Cons: I am handicap, I travel with a scooter. We let them know months in advance and still they did not plan or assist. My scooter was not brought up in Brussels or DC, I refused to leave the plane in DC until they finally brought it to plane. They sat me in row 38...I can only walk a few feet so the airline failed in every aspect...epuc fail. I will never fly Brussels airlines again.

Pros: The food was okay but thats the best thing I can say.

Cons: There was someone that pooped themselves, another that threw up, and the flight attendants were so rude. They kept spraying stuff in the air and even those of us sitting, so much in fact I had an asthma attack and had to use my inhaler. When I told the attendant, she said "theres nothing I can do," and kept spraying the air with this awful spray. The flight harmful to my health, exhausting, and uncomfortable. BEWARE OF THIS AIRLINE! I would have preferred not gone on my trip then fly this airline!

Cons: Delayed. Crew seemed pretty annoyed to have people aboard. Will avoid next time.

Cons: It was delayed. I paid very expensive to fly on Business to be on the first row. Because every minute count for me on this trip. But it was delayed. I feel I should get a refund for sum of the money I spent
