Top tips for finding a cheap flight

  • 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).

Pros: "Amazing"
Cons: "Nothing really"

Pros: "Seats comfortable. Food was good."

Pros: "Crew was very attentive...food selection was excellent"
Cons: "Nothing"

Pros: "Crew was nice"
Cons: "Screens have poor color quality Seat too small Legroom cut into by electronics box Row 45 next to bathroom and no windows"

Cons: "Seats were really old and outdated"

Pros: "The food was good. The lane was comfortable"
Cons: "The flight was nearly full, and the 767 is a large aircraft. I think it would be preferable if Virgin Atlantic would board the plane by zones, similar to other airlines."

Pros: "The crew was amazing and effiecent. Had weather delays, bag got left, but got it the next day."

Cons: "Getting home 5 hrs later than planned"

Pros: "Boarding process was very efficient and crew was very pleasant and helpful. Seats were reasonable for economy."
Cons: "Meals were very small but tasty. Movie options were random but enough to keep you occupied."

Cons: "at last minute itinerary was changed.. instead of routing through Brisbane, was now routed through Sydney. Flight from Sydney to LAX was delayed by 4 hours, then missed flight LAX to LAS... overall long delayed arrival. Checked the route through Brisbane, and those flights we're all there, departed and landed all on-time... so wondering what the reason was for the change of the itinerary without a cause (no cancel or delayed flights through Brisbane)"

Pros: "Everything (with the exception of the subject below), thank you. One thing that really surprised me, though, is how much I liked the eggs (on both flights) and what went with the eggs, like the spinach and potatoes and bacon on this flight and the potatoes and sausage (and was there something else?) on the next flight. Kudos for making something that has got to be cheap taste good. Thanks."
Cons: "Come to think of it, there was one thing that I didn't particularly like, and that was how the headphones only worked on one side only (there was only audio on one side). At first I thought that maybe I had just gotten bad headphones, but the my next flight was the same: the headphones also only played audio on one side."

Pros: "I loved the in flight entertainment, and there was always so many snacks and drinks available for free!"
Cons: "For boarding, we had to walk a rather far distance due to construction."

Pros: "Service, pilot updates, and seating were all great!"

Pros: "The food was okay"
Cons: "The gate was Jane without announcement"

Cons: "luggage never made it to Boston? Don't know who's fault it was.Problem was corrected."

Cons: "The plane seemed to be a little bit old, especially entertaining equipment"

Pros: "Food and service was ok"
Cons: "Delayed at the airport. Very little leg room and hot while waiting to yake off. Entertainment was really bad. Bad screen and sound quality was awful."

Pros: "Plane was about 30% full so plenty of room to stretch out. Friendly crew."
Cons: "Flight left 50 minutes late because they'd lost the paperwork and had to get new copies.... not very professional! I can understand a delay due to weather or technical issues but losing paperwork shouldn't happen. The food portion was very small for an international flight."

Pros: "So much food!! They kept bringing food out the whole flight..The seats were great. It was a very comfortable flight"
Cons: "no complaints whatsoever!"

Cons: "Once In London, we were told by British Airways that was flying us to Nice that Delta had “lost” our infant electronic ticket - It took 1.5h to get new ticket reissued! We missed our connection and had to wait 3 more hours for the next flight - We were somewhat lucky as multiple flights were delayed/cancelled that day - I will avoid using Virgin Atlantic in the future as they need Delta and British operate their flights and this makes it prone to issues like that"

Pros: "Francesca was the flight attende t that I had most the most interactions with was very friendly and warm."

Pros: "Crew was very nice helpful and attentionate Entertainment had plenty of variety maybe not so many new movies but enough to find one you have not seen or classic you could watch again Food was good"
Cons: "We weighted our hand luggage at the counter and then they ask again during boarding little confusing"

Pros: "Service"
Cons: "The seats are a bit uncomfortable for such long flights. Crue was excellent"

Pros: "Efficient, friendly, on-time!"

Cons: "After 14 hours the seats were like sitting on spikes"

Pros: "Good entertainment, food and in-flight crew"
Cons: "Because this flight was delayed it was a miracle (involving running til my throat literally bled) that I made my connection. Ground crew could not have been less helpful - even to my friend who they knew was trying to get home to attend a family funeral."

Pros: "I was very impressed by the generosity you show concerning food och drink. the staff was kind and glad."
Cons: "I never understood how to connect the earphones to the screen so I couldn't ser any movie. But - I could have asked the staff of course ..."

Pros: "We paid extra for more legroom and it was totally worth it."
Cons: "The regular seats were so lacking in leg room that I could not cross my legs, reach the floor to get my glasses when I dropped them, or even get my carry-on out. There is no way to get into the "brace for impact position" with arms over your head and head in your lap! This is really unsafe, not to mention really uncomfortable. The flight was long, so comfort would be nice! Our first flight was regular seats and I was pretty miserable and I am a slender woman 5'6". The extra 3" was great, and we had to pay more on the return trip. The FAA should be investigating seat size and safety on planes."

Pros: "A large selection of movies, shows and music to choose from. Flight crews were attentive and friendly."
Cons: "The narrow space between each rows for passengers to move from their seats."

Pros: "This is my new favorite airline. I loved the staff and all the amenities. I was so comfortable and the food choices were great. I felt like I was cared for and my comfort mattered."

Pros: "Entertainment system worked well. Good choices."
Cons: "Food decent, but not enough fluids offered during flight . Was very dehydrated by end."

Pros: "Neat plane, good food and service"
Cons: "The entertainment screen was very dark. To bad since there was an ample selection of movies."

Cons: "Delays caused us to miss our flight from London to Vienna"

Pros: "The enforcement of the quiet time to sleep on the flight. The excellent meals. The quality of the entertainment system."

Pros: "Very nice staff"

Cons: "Seats need more padding"

Pros: "the food was very good and they hd a good list of selections of movies."
Cons: "the crew was very dry. they did not seem too happy."

Pros: "The crew where very attentive and helpful."
Cons: "The ticket agent was anal about 1-2 kgs for our checked luggage and even weighed our carry on luggage...which no agent had done on our entire trip from atlanta to melb. Seemed pointless and a hassle for 1-2 kgs."

Pros: "The service, the service. My wife got a cheese and fruit platter after dinner. Crew went out of their way to make us feel special and welcomed. Excellent service."
Cons: "Nothing to complain about."

Pros: "There are lots of relatively new movies to choose from."
Cons: "The complimentary headset breaks easily. Tray table was broken and they can't fix it. Very small bathrooms, knees almost touch the door when sitting down. Food selection for dinner ran out quickly, resulting in only 2 choices and one is hot spicy, so basically only one choice. All beverages are given out in small cups, even water is given out in small cups increments (finish in one gulp), they don't even give out small bottles of water. No complimentary packet (eye shades, socks etc.) , not even a barf bag for collecting trash."

Pros: "I liked the food and refreshments and the on flight entertainment was good.."
Cons: "I didn't like the boarding process.every other flight I've been on they board plane by rows.on this flight everyone was boarding at same time which was annoying and held up the boarding process.."

Pros: "very incompetent crew carrying out orders for a very cheap airline."
Cons: "There was nothing to like, attendants were rude, seating was horrible, No room, no snacks, counter persons were even worse, tried to contact virgin australia over 12 times for booking confirm and itinerary, no replies ever, none from HQ in Brisbane. Virgin has NO customer service whatsoever, all they want is to take your money online and do nothing for paying customers. "Paying Customer", remember who we are??? The ones that pay for the worst service in the world. Well done Richard Branson!!"

Pros: "."
Cons: "For an international flight, the plane was too small, cramped and uncomfortable. Food had to be purchased. No entertainment what so ever. Previous I took a VA flight to Perth from Melbourne. Same distance, bigger plane, entertainment on seat backs and a meal. This flight soured me."

Pros: "Audrey agent at the counter at Heathrow was amazing assisted me in getting my bags located and transfer from air malta to vigin"

Cons: "Watch out for checked baggage fees on short haul international flights. If you buy their saver fare, VA charges you $130 to check a bag at the check-in counter. Highway robbery in my opinion! Make sure you add a bag beforehand. Corporate greed at its worst."

Cons: "cabin was nice but cold"

Pros: "I liked the entertainment system, free adult beverages and boarding process"
Cons: "I don't like that they have you pay extra for picking seats that have no extras. No preboarding. No extra legroom."

Pros: "Virgin does phenomenal service; I wish delta would copy their level of service."

Pros: "The comfort of the flight and entertainment."
Cons: "My bag was not put on the correct flight so I had no bag for 3 days, they were slow in getting my bag to Bali from Sydney. It was really unacceptable. I talked to 5 different people to make sure my bag was put on the correct plane, even asked before boarding if it was on and they said yes.The food was horrible, I only ate it because I was starving. Flight was delayed from Sydney to Bali, which caused me to miss my pick up. Not sure if I'll fly with them again."

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."

Pros: "Christina brown was amazing at gate"

Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."

Cons: "The main economy seats were far too narrow."

Pros: "I always have a consistently good experience on Delta. Everything was great."

Cons: "It was a Great flight. I always enjoy flying Delta"

Cons: "My flight was delayed almost 3 hours. Not good. Once in the air it was fine."

Pros: "Everything ok. I was hoping to buy food but glad to see almonds as one of the free snacks. Delta seems to be upping its game a bit lately."
Cons: "No US carrier seems able to master smooth boarding without standing waits."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."

Cons: "1.5 hour delay...no reason given!"

Cons: "Flight was delayed and completely packed so our family could not get seats together"

Pros: "Boarding was easy for a large number. Seats were comfortable. The crew was pleasant and attentive. The food was very good actually. Love the Mile High Tea!"

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "Crew Entertainment Service"
Cons: "Boarding on most airlines is a bit chaotic they always call out zones and often they aren't listed on your printed ticket otherwise was ok"

Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."
Cons: "Economy is very tight quarters."

Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"
Cons: "Nothing disappointed, butt i didn't have any good besides pretzels."

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"

Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."

Pros: "I love the new snack choices! Way to go Delta for offering Kind bars now!! This is awesome."
Cons: "Tiny old plane, props blocked my window view, no entertainment system."

Pros: "The staff of the flight were very friendly and attentive. They were great!"

Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."

Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Attendants and entertainment"
Cons: "Delays for no explained reason"

Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "Flight was repeatedly delayed. Ended up being over 3 hours late to depart due to weather. Another delay due to mechanical problems."

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "nice snack"

Pros: "Manchester Airport first class. More services and convenient than JFK and Atlanta. Check in and gate staff great in Manchester. I"
Cons: "Plane change JFK. Staff with TSA looked like they slept in their uniforms. Information incorrect on wifi customs and caused delays. Customs agents first class."

Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."

Pros: "Left on time, arrived early. Great cabin service, attentive and polite. Comfort Plus seats are worth the extra few bucks."
Cons: "Nothing. Low rating for entertainment only because there really wasn't any, but I wouldn't have used it anyway, so no big deal."

Pros: "All went as planned and expected. No thrill- like taking a Greyhound bus in the old days...gets you where you are going but without much pizzazz New seats and quite clean, but the new seats were very hard and uncomfortable after an hour."
Cons: "Somewhat claustrophobic and always wish the drop down tray table behind could be disconnected from my seat. When the passenger behind uses the tray as a set of bongo drums to keep beat with his headphones it is a pretty miserable trip."

Pros: "They were smiling and very welcoming"

Pros: "There wasn’t anything to highlight as good. On this trip except LHR was organized and clean. The boarding was a free for all after the elderly and young had been boarded footstep as they should."
Cons: "The ground staff were rude and officious"

Pros: "It didn't crash."
Cons: "Food no screaming babies . Comfy seats and armrests,"

Pros: "Staff were kind and courteous."
Cons: "Late departure and uncomfortable seats."

Cons: "There was not enough room for all the people’s cabin size luggage. They allowed people to get on board with big coats once they’re in the plain they take off the coats and place them up. Those coats take the same space as a small suitcase. I asked the fly attendants for assistance and they didn’t even pretend to care about the situation. I had to put my luggage under the seat for the entire flight, which ended up reducing the very reduced legroom. What this airline is trying to do is; to charge passengers twice for cabin size luggage. This has been my worst experiences with airlines. Lufthansa is definitely an airline to avoid."

Pros: "Flight crew made up time to arrive on time despite late arrival. They are pretty amazing - they got a plane hundreds of miles in the same time it took the ground crew to get my bag from the plane to the baggage claim."
Cons: "Frankfurt is just an awful airport. Too many landings and not enough infrastructure. Also tired of planes having to park thousands of yards from the terminal. The time to get the bag is as long as the flight. Each about 55 minutes. There is very little about German efficiency here."

Pros: "One flight attendant in particular was outstanding, Eva. Because of her, I would definitely consider Lufthansa for our next trip to Europe!! She mot definitely went above and beyond in her service and professionalism."

Pros: "Best part was how Lufthansa took care of travellers whose connection time was short. They had ground crew waiting and who escorted us through customs, and then drove us to the gate. This is how passengers should be treated. ~ Excellent movie selection ~ Great flight attendants"

Pros: "Some how i ended up in the "small child zone", The crew was very kind and moved me to another aisle seal towards the front of the plane. Crew would come by with liquids quit often, The food was very good quality. huge selection of entertainment options."
Cons: "A very long wait for luggage, That may have been the fault of the airport."

Pros: "We only had carryons and they took the. From us before boarding the plane."
Cons: "They should tell people that there is delay and that they will take their carry one"

Pros: "Not much"
Cons: "Almost everything"

Pros: "Once again, the in-flight crew was excellent. The flight was good, but no entertainment is provided."
Cons: "Another late take off, probably because the incoming connections were late. So it was good that the airline delayed the connecting flights. However, this leg of the trip was so late that I barely made it to third leg of the trip. A huge problem is that each of these international airports require that you go through the security check again. For that reason, connecting legs of trips through these airports should not be scheduled so close together. Heathrow is the worst, with security staff that, at best, don’t care that you have a close connection to make and just ignore your pleas to speed up the process, and at worst, are just plain rude."

Pros: "Only an hour and a half but perfect service and even a nice meal. Because of the delay there were a lot of questions to the crew but they managed to keep travelers calm and happy."
Cons: "Flight was delayed but that had nothing to with the crew and the service."

Pros: "Was not allowed on flight"
Cons: "When I missed the connection from the first leg of my flight and purchased the ticket from that leg to finish my itinerary, Lufthansa cancelled ALL of my return tickets. Both Lufthansa and my travel agency pointed the finger at the other and I had to purchase another $1000 ticket to get home. There was no cancellation emails or any notification. I didn’t know my tixkets were cancelled until I was trying to check in. Worst experience ever!!"

Cons: "Missed so there was none Spent night in Minic"

Pros: "Comfortable seats, good legroom."
Cons: "Slight delay."

Pros: "Made up most of the time. Latrobe leaving due to queue."
Cons: "That I did not know in advance there was a snack. Would have odered vegan as it was had nothing."

Cons: "At the gates they said that nobody could bring more than one piece of carry-on items Dash completely catching Everyone by surprise. They took a backpack from me, and it has now been lost."

Cons: "No bridge in Frankfurt - long taxi and then 15 minute bus ride to the terminal; had to go through security again; mad dash to catch connecting flight (which also had the 15 minute drive to the plane - again, no gate in the terminal! Shambles!"

Cons: "They cancelled my flight"

Pros: "Nothing"
Cons: "No body helped me. My first flight got delayed and missed my connecting flight. People were rude and showed that they didn’t care. I had to wait 4 hours for the next flight. I received little compensation"

Pros: "The counter staff in Heathrow was great"

Pros: "On time and good service"

Pros: "Was great,on time,no issues,they send me the flight connection gate on my email.*****"

Pros: "Good attitude"

Cons: "The flight took off 2 hours late they must have known it was going to be that late, yet they lied saying that it was on time, forcing you to come to the airport early, then when you get to the airport they did the - oh its going to be 20 minutes late, no 40, no 1.5 hours late, heck it will be 2 hours late etc. Micro-tight seat pitch - I could barely sit in the seats."

Pros: "All airplane was on time"

Pros: "After the delay I was given a spot on the direct flight so I didn't have to deal with the complications of the connecting flight. The staff was nice and helpful."

Pros: "Fast and efficient boarding"
Cons: "N/a"

Pros: "Great service and flight crew"

Pros: "Easy check-in and helpful staff. I would absolutely fly with Lufthansa again"

Pros: "It was good the checking desk person was polite and done her best to put get me on to British Airways flight to get to my destination on the same day."
Cons: "But we waited tilll 12.30pm still flight took off at 14.00 and arrive in Dubai at 23.50pm instead of 22.30pm person went home who suppose to pick me up. I got to the place I was staying at 01.39am which was very uncomfortable. I will never fly again with Lufthansa Airline it use to like British Airways but definitely they have lost the customer touch."

Cons: "The plane lands a considerable distance from the airport, you walk across the tarmac in the rain to a bus, and then the bus ride is almost 15 minutes. I expect Lufthansa to have a better berth at Frankfurt."

Cons: "Flight was 30 min delayed . When we landed, the jetway was someone mispositioned and it took even longer to get us off the plane - nearly 1 hour late. Missed my dinner appointment as a result and generally bad start to my trip to Munich . Very disappointed ."

Pros: "Nothing"
Cons: "Nothing"

Pros: "Nie odbyl size powodu opuznienia samolotu z Chicago do Londynu"

Pros: "the woman who helped me at the boarding gate was great! Lounge was really nice!"

Pros: "The energetic crew who served with a smile"
Cons: "The tea was not strong and was served lukewarm and movies not up to standard.how about new blankets...and food only a choice between 2...chicken or pasta..why not beef or mutton?"

Pros: "Timing and the cost was good. Crew were friendly. Did. Or feel a racist service like in Germany itself."
Cons: "No entertainment. Too much hand luggage even though we had the allowed size bags but it seemed that people use more than the allowed limit."

Pros: "Was informed that boarding would be delayed but began within minutes. Arriva time was spot on"

Cons: "Most cramped seat I've ever sat in. Couldn't even sit because my knees hit the seat in front, before my but was in the chair."

Cons: "Same as Abu e"

Pros: "Nothing no communication for delayed flight lost luggage. Just lines everywhere to fill out forms with only 2 employees worst experience ever"
Cons: "No communication. Flight delayed no answers. Just long line to be put on a waiting list"

Cons: "First flight mechanical issue so couldn't make it to any of my connecting flights and they had to reroute me, however they couldn't get me to Torino so they got me to Milan and I had to take a two hour bus and then the metro to get where I needed to be. And it took them over an hour to reroute my flight!"

Pros: "Even on such a short flight I got a sandwich. It was a salmon sandwich which I never had on any other flights. They usually serve cheese or ham or chicken in the Middle East. It was nice to have something different and nutritious."

Cons: "Flight delayed 1.5hrs after landing in Denver."

Pros: "Priority boarding with small kids"
Cons: "In London I was required to ask fro this priority boarding with kids if not asked I would be queuing with small kids for 15 minutes.. (whilst In Frankfurt we have been invited to be boarded as first ones without asking for it.)"

Pros: "Heathrow had a lot to offer between flights. Our gate was in the middle of everything."
Cons: "We were late boarding, which left very little time to connect with my next flight in Frankfurt."

Pros: "On time, nice and professional personnel, kids-friendly, tasty & free food & drinks. Great airlines every time!"

Pros: "I loved how friendly the airline attendants were."
Cons: "I didn't like how in the Munich airport I couldn't find a place to plug my phone in. they should make those more accessible"

Pros: "Overall a nice and good flight"
Cons: "Just a detail, my “head holder” (not too sure how it is called) would not hold in position. Also, staff was a bit slow to come after being called, I had to go and ask for water by myself at some point since no one was coming after 15minites of waiting..."

Pros: "Impressive service... amazing crew, very friendly and professional"

Cons: "Still don’t have my luggage yet"

Pros: "the crew was wonderful, we got a nice Wrap and water, wine or coffee for free, not all airlines serve it anymore, we were on time and I got whatsapp message with updates of the flight"

Cons: "The flight from Manchester to Amsterdam has been delayed which led insufficient time for me to transfer to HK"

Cons: "I congratulate the KLM crew!"

Cons: "Fix the damn KIOSKS at Vienna!"

Pros: "Onboard crew were nice and polite. Flight was on time (a rarity)."
Cons: "The boarding crew was rude and unpleasant, the plane was boiling hot."

Pros: "Food and service"
Cons: "Working wifi would be good. Better A/C. More comfortable seats"

Pros: "Friendly crew"
Cons: "KLM lost one piece of my luggage"

Pros: "Crew was ok."
Cons: "Screens need a serious upgrade, my seat didn’t recline all the way nor could it be restored to an upright position. Not very comfortable and I paid for a seat upgrade."

Pros: "The flight was smooth, the service was friendly, and the food with plentiful."
Cons: "Too much activity in the cabin during the flight."

Cons: "I called for a crew member 5 times and waited 25 minutes for anyone to help me with just some water. I had to get up and go to the very back of the plane to ask for some water. The plane was hot and no air to be found. This was all after we had to get back off the plane before takeoff. It was terrib"

Pros: "Very personable staff. Food acceptable for airline fare. Ticket price was outstanding."
Cons: "Paid for extra legroom, but very narrow seats not comfortable. Very difficult to sleep. Old plane--could not hear movies and unclear screen. Music sounded OK and choice was good."

Pros: "The flight AMS to MEX was smooth, very helpful personnel on board, we enjoyed a bit more space and the seat seemed a bit more comfortable."
Cons: "Besides the seat relative comfort, it did not recline much at all, i wondered what the extra money (at least $5 or $600) got us. The food, wine/ beer service was same as regular economy, the boarding took place at same time as economy, no drink before take-off if only sparkling water. And the plane was old generation 747 and the entertainment was same vintage: screen was not very bright and the selection of films was poor. No plug to charge electronics. We were disappointed with KLM when comparing with other airline companies offerings when you book in Premium Economy."

Cons: "Poor food, flight attend and finally baggage missing. Overall experience is extremely bad."

Pros: "short, sweet and to the point. 1+ hour flight is usually an easy hop."

Pros: "Amsterdam airport and Rome airport were as breeze to navigate, even only knowing English"

Pros: "I am so grateful to have been provided delicious and filling vegan meals on this long flight. Thank you for offering a dietary option that is compassionate toward animals and contributes less to climate change! Now if only the planes were powered by clean, renewable energy... Hopefully that will become a reality someday very soon! Oh, and also the crew on this flight was exceptionally kind and helpful. Thank you so much!"
Cons: "I did not enjoy the turbulence, which I suppose is unavoidable. More importantly, I felt quite guilty about the greenhouse gas emissions of my flight. I have decided to cut down on my air travel as much as possible as a way of reducing my carbon footprint."

Pros: "More than adequate room, And very good service from a very professional staff. Head and shoulders abovevany American carrier, and several European lines I have flown."
Cons: "Can't think of anything."

Pros: "The entertainment options were good."

Pros: "The crew was fantastic! Our needs were constantly being met and just about the time you thought you might want a snack or a meal, the attendants were already heading down the aisle. Because of an allergic reaction, I asked for ice a number of times and the attendants were more than happy to meet my needs."
Cons: "The seats were very close together. The trip from New York to Amsterdam seemed a lot more comfortable than the return flight. The food from NYC JFK was better than the food from Amsterdam. The movie selection on both flights was a little disappointing."

Pros: "She was cheerful and genuine. I have dietary restrictions but was unable to preorder a meal. She went out of her way to find an available meal for me. I also saw her bring other passengers extra snacks and drinks."
Cons: "Cramped seating."

Pros: "Crew"
Cons: "N/a"

Pros: "Very friendly crew going out of way to assist in making trip comfortable"
Cons: "Had travelled KLM to Amsterdam on my first flight 27 years ago and the aircrafts are stuck in that age! Lousy seats, poor quality bathrooms, lousy screens, prefer not to fly them"

Pros: "Nothing really"
Cons: "Flew KLM 27 years ago and the airlines seem to be stuck in the same era. Food is poor quality... Have you recently checked the Gulf carriers."

Pros: "Food was just fine, movie selection very good"
Cons: "Uncomfortable seat cushions, lights were truned on too early (1.5 hours before flight landed)"

Pros: "Service, technology"
Cons: "Could not print by boarding card and was not allowed to board in Amsterdam"

Pros: "Boarding was quick, Flight on time....just a regular service and plane"
Cons: "Terminal 3 Manchester is not worth staying longer then necessary, loud music, crowded....old"

Pros: "Friendly staff, good service and on time departure/arrival."

Pros: "The staff the facilities the food all ******. Will definetly look forward to choose both delta and KLM"

Cons: "Amesterdam airport employee was really rude"

Pros: "Ground staff at Manchester very helpful"
Cons: "Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros."

Pros: "Great crew service. Among the best ever."

Cons: "KLM had bumped us to a later flight for no reason and again we had to call with a long wait to get our original connection restored, However, we did not get boarding passes during checking in Europe and thus had to go outside security in Detroit to the main check-in gate and wait 30 minutes to get the error resolved. Then it was back thorough security and a rush to the gate to get there in time to board. Lost our original seat assignment and wound up in the last row at the tail of the plane. Extremely poor coordination between KLM and Delta who operated the flight."

Pros: "Overall, my trip to Cardiff via Amsterdam was smooth and delightful. I've flown a few short trips this summer and I was pleasantly surprised to find KLM still offered complimentary snacks. What a refreshing change!"
Cons: "There was no entertainment which is why I assigned that category only one star. The boarding process in Amsterdam could have been a bit smoother. Announcements were no clear."

Cons: "The crew on the Lagos Amsterdam route (in economy) are particularly unfriendly and brusque. This is my experience each time i fly this route in economy"

Pros: "Staff, service"
Cons: "Nothing"

Pros: "Crew was excellent"
Cons: "Economy was very tight! Seats were uncomfortable"

Pros: "We really liked the KLM people, from the check in crew to the flight attendants."

Pros: "They flew full speed to catch up with the delays."
Cons: "Departure was scheduled with one hour delay. When everyone was boarded they mentioned a leaking toilet. It took them 1,5 hours to disable the toilet. In the mean time, no drinks, no snacks, nothing. So we should depart at 18:00 but it became 19:30. Our first drinks and meal was no earlier then 21:00. The crew should have anticipated better that the technical problem would at least take one hour and give everyone a drink at least."

Pros: "--"
Cons: "One and a half hour delay on a 50 minute flight. Flight was operated by Cityjet on behalf of KLM. Never have I seen such bad customer service: from rude people at the bagage drop off to incompetent hostesses at the boarding gate."

Cons: "Completely none sense to change the time of départure (30 min earlier) with just a simple email 24h before and w/o sending a text on mobile phone."

Pros: "Excellent crew made this flight very enjoyable. A lot of information during the flight about the route, arrival times and clear explanation of the departure delay. Very friendly and attentive."
Cons: "Only 1 drinks round on a 3h flight."

Pros: "Food was relatively good"
Cons: "We had ourtrip from San Francisco to Amsterdam which is one of the longest flights ever, andthe entertainment system wasnt working, we kept on telling them several times but nothing happened and at the end they wereeven avoiding us. By the end of the trip when we were approaching Ams, a hostess came and she gave us a $25 dollar discountvoucher to be used in our next trip, this is totally not acceptable!"

Pros: "Flights left on time, arrived ahead of time. Seats comfortable. Baggage arrived quickly. No charge for wine/beer, although I do not imbibe when flying long distance. Food ok for airline food."
Cons: "Unable to pick seats in advance,, were assigned seats that did not recline for 11 hour flight. One bathroom not functioning. Very limited movie choices for inflight entertainment. Seat belts much shorter than other airlines, so very confining, unable to loosen to relax in any position other than sitting straight in seat. In Rome had to check in & go through security at Terminal 5 then get bussed to Terminal 3. Only airport where we had to take out all electronics, including converter plugs, headphones, etc, place in a flimsy clear plastic bag ( that broke ) to go through security. Line to check bags pretty slow for number of passengers. Glad we had plenty of time."

Cons: "My Kosher meal never made it on-board. The cabin (and the airport) were way too cold"

Pros: "Very helpful assistance staff, food and drinks delicious, excellent service onboard"
Cons: "At Denver assistance hadn’t been arranged"

Pros: "Great flight"
Cons: "Nothing"

Cons: "Crew was fantastic on United!"

Pros: "I watched a good movie."
Cons: "The plane seemed old. Food was pretty lousy. Hummus was dry, crackers were stale."

Pros: "Crew was attentive. Seats were reasonably comfortable. Good selection of entertainment."

Cons: "Need power outlets at seats."

Cons: "Over two hours delayed. Had to carry on carry off my bags that were heavy. Messed up my schedule. Had to incur extra charges at San Diego destination due to the inconvenience."

Cons: "We were delayed in Chicago due to weather coming home from Europe. We were not allowed to use the business class lounge even though we paid for business class tix. My family is still sitting in the airport waiting on their flight to dallas. We have been up now for over 24 hours. We should be allowed to be someplace comfortable for the price of the business class tickets. poor form on Lufthansa’s part."

Pros: "Service on Lufthansa is better than most us carriers"
Cons: "The gate agent did notice I was changing carrier but did not distinguish my bag at Check in"

Pros: "The entertainment can stream a large library of movies to your device"
Cons: "Seats only marginally comfortable, weather delays caused us to leave very late (although I made my connections, many did not)."

Pros: "Loved the food. Great for flash frozen and then microwaved. Service was excellent, much better than the going flight."
Cons: "N/A"

Pros: "No problems to deal with"
Cons: "Nothing"

Cons: "The team in the airport seemed unsure about how to handle situations including checking people in, using the new TSA pre- check line, & resetting is he security equipment."

Pros: "Extraordinary efforts to accommodate bags in the overhead bin."

Pros: "The crew was stellar! For a change, the flight wasn't too full, and one of the flight attendants went out of her way to move me and my husband to a row where we could have the middle one open. Another flight attendant was so pleasant and friendly, without being in the least intrusive, and so was one of the flight crew who I by chance exchanged a few pleasantries with. The food was reasonably good, although oddly leaning a little too heavily on the carbohydrate side. The WiFi actually worked, and the entertainment offered not bad. I liked that there were a few off-the-beaten-track choices in movies and TV documentaries."
Cons: "What I didn't like was after booking a ticket, then calling before my round trip to see if I could make a change of one day for the return. I was quoted a price of $4,870 to change two $300 tickets. I opted to not change and expressed my dismay at this preposterous fee to change. Her best suggestion was to check again after the trip out (Denver to Heathrow). I did, on Friday April 13th, when I called Lufthansa (it was a Lufthansa flight operated by United) I was told it was a mere $600 to change 2 $300 tickets. Again my husband and I decided not to do this. Yet, when we arrived at Heathrow for our return trip, we couldn't get our boarding passes because they said we were too early for our flight tomorrow. Somehow they'd changed it after we declined to make the change! We were able to get it changed back and get on the flight, but got not a word of apology or explanation. Still waiting to see if any kind of charge shows up we will have to dispute. Not at all happy with Lufthansa for this."

Cons: "No one could get their story straight and actually lied! I was sent a text (I was already at the airport) that the flight would be delayed due to "aircraft maintenance". Not true in the least bit. Then when we finally landed in Denver (nearly every person on that flight missed their connecting flights) we were told the system said the delay was "due to weather". Another lie. Then they announced there would be gate agents to meet us when we got off the plane to assist with connecting flights. First gate agent said "I have no information you have to go to gate 56". The person at gate 56 said "I don't open for another 15 minutes so you have to go to gate 39"! The real story? They made us change gates 5 times in Fargo! The gate attendant was using the "F-bomb"! It wasn't aircraft maintenance or the weather. They couldn't get the walkway to work! In the end, we still left from the original gate and had to walk outside on the tarmac to board the plane. Why didn't they just opt for that to begin with and avoid all the missed flights? My measly voucher isn't nearly enough compensation and if United ever expects me to fly with them again I am expecting a full refund (as other passengers received- I witnessed the manager in Denver authorize a full refund for another passenger but only offered me $50)"

Cons: "Flight was cancelled, instead of a direct flight back, we had to go to Munich and then fly to LA"

Pros: "Flight departed on time and landed ahead of schedule."
Cons: "United baggage check in at Orlando Airport was chaotic with huge crowds, inattentive United staff ignoring passengers, and a baggage conveyor belt that was broken down."

Cons: "It was super cold. Miserable."

Pros: "Nothing"

Pros: "Security was quick and efficient. Boarding was extremely organized. The airline attendants were attentive. The pilot on United informed us when the possibility of hitting turbulence occurred so we could adjust accordingly. Overall, great travel experience."

Pros: "Boarding and landing ahead of schedule"

Pros: "Generally it was ok. Travelling is so horrible these days that "ok" seems pretty great."
Cons: "My bag was lost but my husband's, checked at the same time, made it."

Pros: "Nothing"
Cons: "Refused to delay connecting flight in Denver even though severL of where already on ground in delayed flight coming into Denver. Albuquerque flght was still at gate when I got there, having run through airport along with several others. We were refused admission to plane despite delay being United's fault. Unacceptable! I will avoid flying United in the future whenever possible"

Pros: "I didn't fly.I bought the ticket for my son. He had no complaints. You should ask in your questionnaire if the booked flight was for self or someone else."

Cons: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"

Pros: "Boarding was uneventful, but I wish I could have gotten a gate check....I;m 76 and getting my bag above the seat is difficult. But the gate attendant said there was no gate check on that flight."
Cons: "I had a center seat and that is very uncomfortable for me."

Pros: "Got there on time."
Cons: "Private screening does not work well. Very little kneeroom. No room in seat back pockets to put anything."

Pros: "On-time departure from Cancun but early arrival in Denver (relatively mild jet stream?). Otherwise, fairly typical United cattle carrier."

Pros: "The pilot apologized profusely for our delayed departure, and offered us free in-flight TV. He made up time, and we arrived only 30 minutes late (take-off was delayed over an hour)."

Pros: "Nothing."
Cons: "Airplane went to the wrong airport and caused 3 hour delay . Missed my connecting flight."

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

Cons: "Delayed and got downgraded without refund of difference"

Cons: "I wish I could have gotten more beverage (water) during the flight. Very dry in the cabin but all-in-all, it was a pleasant experience."

Pros: "This leg of my journey was fine. Sat in the middle seat. Was able to sleep most of the way."

Pros: "The actual flight was great, employees on the plane were very friendly"
Cons: "We missed flight by 5 minutes and employees were not helpful at all. We had to stay the night in Houston due to this fact and caught a flight out the next morning. The employees were all ready to get off work and left w/o helping us."

Cons: "Our plane was United, so I don't think this reflects on Lufthansa, but rather United. The plane entertainment was extremely outdated and there was not enough room in the overhead containers for everyone's carry-ons. This problem made boarding a very long and aggrevating process."

Pros: "United seems to be recycling which is a good thing."
Cons: "The obnoxious child sitting behind me. He kicked the seat and pulled on the tray."

Pros: "Instead of a 4 hour layover in Denver, I was easily able to get on an earlier flight to slc thank you to such a wonderful front desk agent. Even the crew members on board were so pleasant you could tell they truly enjoy their job and want to make for an enjoyable flight. Thank you United!! Will be flying with you again!!"

Pros: "Extremely friendly crew"
Cons: "No entertainment, but that is expected"

Pros: "Efficient boarding"
Cons: "Very rough flight but pilot did a good job of keeping passengers informed"

Pros: "My flight home was surprisingly faster than I thought it would take and the entire time I was comfortable and relaxed."

Pros: "The crew members were welcoming and the cabin was clean."
Cons: "Only limited drinks were available and then the flight attendant forgot to bring the water I requested. Thankfully it was a short flight, so it wasn't that big of a deal."

Pros: "Customer service at Dulles was helpful"
Cons: "My trip was jacked up on both ends, starting with cancelled flight at 11 p.m. the night before, phone calls to United to change flights on the way out, and then maintenance on the way back home, which caused me to miss my connection in Dulles. Horrible accommodations, bad replacement flights, baggage service in Syracuse was dishonest and apathetic. All around bad."

Pros: "I've only used United a handful of times between London and New York. They've been okay. The worst flight was on an older plane that felt like it'd been built in 1975, and the entertainment was rubbish. The staff however are always pleasant and accommodating. Their service was just as good on my heavily delayed return flight, and managed to handle the tired, short fused customers with aplomb. Hats off to them."
Cons: "My return flight from EWR to LHR was delayed by 4.5hours. Initially it was a 20minute delay; then we boarded the plane, only to sit still for an hour due to technical difficulties. Then we were delayed by another 30 minutes. Then we were asked to leave the plane as a replacement jet was required. It was meant to take 15 minutes, when it actually took at least 1.5 hours. It was a 6.10pm flight, and we boarded the new plane at 9.30pm. We eventually jetted off at 10.30pm. I'de received 10 text messages stating each each rescheduled/delayed departure time. Sadly, it's the worst flight I've ever had. I ended up 3.5 hours late for work, missed an important business meeting. Shame."

Pros: "Price was good but had to pay an extra $25 for baggage. Guess this is the new normal ans since I dont fly much I wasnt aware."
Cons: "Delayed flight due to a maintenance issue."

Cons: "Flight was delayed three hours which screwed up my connecting flight and put me in Minneapolis for the worst of the rush hour traffic"

Pros: "So many maintenance delays, I wouldn't make any connections. Gate attendants were crabby and not very helpful."

Pros: "Frankly, there wasn't much about this flight that I liked besides the fact that I was lucky to have an empty seat next to me. Otherwise it was terrible."
Cons: "To start, my flight was delayed an entire hour due to our plane being towed from terminal B all the way to terminal C. I feel that is something that should have been looked into considering where the plane was coming from previously and the flight should have been planned for a later time to accommodate the wait time. Then as I am about to board the plane overhead compartment space ran out of room forcing me to check a bag which is why I brought a carry on to avoid any confusion when it came to checking the bag itself. When I arrive in Denver I go immediately to the baggage carousel and wait almost a half an hour for my bag which never shows up. Turns out when being forced to check my bag at the door it was tagged incorrectly with someone else's name and also a different flight schedule then my own. The Denver United team helped me find my bag, but after an hour and a half the ride I had arranged had left, I was over two hours late for a get together I was attending, with no way of getting home. I have never had such a terrible flying experience like the one I experienced on 12/11/15. I will never fly United again. I work in customer service I understand that people make mistakes but bottom line is to mark someone's bag with someone else's name is an extremely careless mistake that cost me my way home, my time, and my patience. Needless to say I was extremely unhappy and disappointed with United yesterday."

Pros: "Nothing remarkable, which is the way I like to travel!"
