Top tips for finding cheap flights to Iceland

  • Book at least 5 weeks before departure in order to get a below-average price.
  • High season is considered to be January, November and December. The cheapest month to fly to Iceland is January.
  • Morning departure is around 19% cheaper than an evening flight, on average*.
  • To get from Denver to Iceland, look for flights out of Denver International Airport (DEN) to Iceland’s main airport, Keflavik International Airport (KEF), in the country’s capital, Reykjavik. This will also put you near top sites like the iconic Blue Lagoon.
  • There are more flight options if you look for ones with at least one layover before landing in Iceland. United Airlines and Icelandair operate a more affordable route with a layover at Boston Logan International Airport (BOS).
  • When traveling from Denver to Iceland, make sure you exchange some of your USD into the local Icelandic króna (ISK). You can do this at one of the currency exchange desks available in the arrival hall of Keflavik International Airport.
  • If long flights like the route from Denver to Iceland are stressful for you, Denver International Airport has a few facilities available to help passengers relax. The airport has both a massage center and a spa.
  • If you are traveling with young children and are planning on renting a vehicle or riding in a car during your time in Iceland, you should inform yourself of the child seat requirements in Iceland. Any child under 36kg (80lbs) must ride in a restraint seat or booster seat. You will always need to travel with one unless your car rental agency can provide it for you.

Cons: "Food options"
Pros: "The Icelandic movie selection with English subtitles was nice."
Cons: "Icelandair is not great for international flights. No free food or booze."
Cons: "The check in was very slow - only one Iceland Air representative was at the counter."
Pros: "Entertainment was pretty good."
Cons: "Seats seemed small for average size person. 2 flights on my 3 leg journey were late departing and arriving. No missed connections but it was close."
Pros: "Crew was polite"
Cons: "Boarding was late"
Pros: "The crew was great. Very smooth flight, no problems or delays."
Cons: "I never took my flight, the customer service to cancelling my ticket would have been a huge help."
Pros: "Reasonable fares. Good baggage accommodations. Denver to Iceland direct. Nice flight staff. The flight attendant pointed out the people who were awake the northern lights which was definitely the highlight of my trip!"
Cons: "Seats small. Surprised no meals unless purchased. But didn’t matter too much I ate before the flight left. And it was nice to have something to purchase if needed. It was confusing where I could purchase my baggage ahead of the me while checking in online so I just paid for it once I got to the airport."
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: "Nice flight. Empty seat between the two of us! Arrived earlier than expected."
Cons: "Nothing."
Pros: "The overall mediocre entertainment was the best part."
Cons: "Bag drop took 75 minutes waiting in a line with minimal signage. The middle seat is not designed to accommodate a small backpack, let alone, my tiny, size 5 feet. There are no snacks provided (7.5 hour flight) and NO refills on WATER!!"
Cons: "Baby in front of me and baby next to me took turns screaming during the entire trip."
Cons: "Technical difficulties boarding and unboarding. Which made it a rush to have to go back through customs in Reykjavik to board the next plane"
Pros: "flight attendants great and accommodating den - kef"
Cons: "it was a little toasty on the plane"
Pros: "Excellent on board entertainment."
Cons: "No meal on board for an international flight."
Pros: "Comfortable planes, nice crew, great pilots"
Cons: "No food served"
Pros: "Clean. Good service. Just way better than most domestic flights in recent memory."
Cons: "Never flee international without getting a free meal before. Pretty sad. Plus, they charged for earphonestoo. Ridiculous."
Pros: "the route and speed of transfer to the next flight"
Cons: "Poor range of foods, limited supply available by the time the crew gets to you. Tea was made in a coffee pot and tastes horrible."
Pros: "Kids get activities and a special meal box. Flight attendants were helpful in making our row restful for my kids to sleep. Nicer flight than I expected."
Cons: "Nothing - would fly again!"
Cons: "No dinner meal served and only one beverage service for 7 hour flight. Had to wait a very long time to order a noodle bowl and beer (not complementary), which were mediocre. Iceland air does not recognize global entry, therefore I could not get TSA pre-check or expedited customs."
Cons: "3 hour delay from Denver translated into a 6 hour delay to my final destination. Food on board is expensive, even when other airlines offer food in their ticket prices. Very likely will not fly on Iceland Air again."
Pros: "The crew was courteous, and polite. Vwry helpful, and the flight was extremely fun, ibe never seen so much in my life, and being able to follow the flight path was my favorite."
Cons: "Because i didnt have an aisle seat, sometimes they seemed to forget I might habe rubbish, but overall they were always walking by to assist. Still a positive."
Pros: "The flight was quiet and I was able to get sleep on the transatlantic leg. Passport control at KEF was quick and plenty of nice places to wait during my layover which had been extended thanks to anweather delay.frie"
Cons: "Hard to rate food when it's for purchase and I didn't consume any. No drinking fountains at KEF Food for purchase only"
Pros: "Great in-flight music and movies. Top notch. Friendly and quick service too."
Cons: "Airport in Reykjavik was awful. They had 5 or 6 flights leaving at the same time out of the same wing and so there were crowds of people standing around with no direction..."
Pros: "On board entertainment was good (i.e., movies, shows, etc.)"
Cons: "No food was served."
Pros: "Very comfortable seat in row 5"
Cons: "The flight from Denver was delayed an hour. Our connecting flight in Iceland DID NOT WAIT for the seven of us. We were supposed to be in Geneva 3 hrs later but waited in iceland 7 hrs the sent to Frankfort Germany before being flown to Geneva 24 hrs after departing Denver. We had two toddlers with us. There were flights on other airlines available without delay, Icelandair had no compassion."
Cons: "First time I have flown on the international flight and there was no food"
Pros: "The crew is always excellent"
Cons: "That you do not serve food"
Cons: "My wife's bag did not make the plane from KEF to AMS. Still hasn't arrived 30 hours later."
Cons: "Depending on the seat you get (aisle, middle, or window) you either can or cannot fit anything under the seat in front of you. Each seat has different space. What I usually take wouldn't fit anywhere but the window. The middle seat space is USELESS as there is something installed that MAY give you about 6 inches from floor to it. The aisle seat's forward under space is a cube shape, so typical carry-ons won't fit there either. As I slept the whole way to Reykyavik, I don't know much about the service. The under seat space may lead me to not booking Icelandair again."
Pros: "Icelandair is great because your connection waits for you even if your flight is late."
Pros: "The crew was nice and it was nice that they gave my 8 year old son an activity bag and free meals. The entertainment center was great. The flight was on time and everything seemed to run smoothly."
Cons: "It felt like a domestic flight in that there wasn't a lot of extra space and we had to pay for everything (food, snacks, headphones, wifi) aside from soft drinks."
Pros: "On time"
Cons: "No food or drink amenities"
Cons: "No blankets and the temp in the plane was freezing. Possibly this is only for this specific flight, very little info on delay and almost no info on what was going on."
Pros: "Nice leg room. Nice crew."
Cons: "Seat very uncomfortable; rear end very sore. TV unit kept coming back on after being shut off."
Cons: "Arrived late."
Pros: "Entertainment options, crew was very polite and helpful"
Cons: "Any overnight flight should provide a meal or better meal options to buy"
Cons: "Meals on menu were not available."
Pros: "Pillows and blankets. Lovely crew"
Pros: "I enjoyed everything about my experience with Icelandair. I am going to be flying into London through them for now on and hopefully on an annual basis!"
Pros: "Was offered a seat so we weren't seated 3 across on our side of the aircraft"
Cons: "I preordered a meal that they didn't get from the caterer and none available on board. Waiting area for flight had no seats."
Cons: "The movies were all old, no new variety. They refused to let us take our bag on to the plane even though it fit in their provided sample bin and made us check it at the gate. There was plenty of room on the plane bins and several bigger backpacks than our small duffle bag! This caused us a lot of extra time spent upon arrival waiting for it"
Cons: "you cancelled my flight, no more Iceland air for us, we had to cancel our entire vacation."
Pros: "Nothing"
Cons: "Flight was cancelled & no alternative flight was offered. Had to spend $350 more for a last minute flight & lost a day's vacation"
Cons: "No food served in economy. Bought a tapas box for 11 euro that was not worth even half that."
Pros: "Flight nice, easy, crew good. Good seats. nothing wrong really"
Cons: "I didnt' realize there was no food at all! Oh well, I guess that's how I got such a cheap fare."
Pros: "Service was good, seat was comfortable."
Cons: "Having to buy a meal on a seven-hour flight is surprising to me."
Pros: "I appreciated the fact that we were able to fly out despite there being a major snow storm and closed airport just hours before our takeoff. We also appreciated being able to switch our connection flight fairly easily once we knew we would be delayed. The staff was very kind and since we had a longer layover in Keflavik, we were very grateful for the food vouchers to used in the airport while we waited."
Cons: "The airline wouldn't make a decision about whether or not the plane would be flying out on time or be delayed until about an hour before our original boarding time. Seeing as the airport and only road getting to the airport were closed, it seems like they would have been able to make that decision and alert all passengers much sooner. We kept calling in to check on the flight status and they said we would receive texts and emails with any changes, but I never did."

The flight attendants were knowledgeable and informative. Our incoming flight was delayed due to snow and ice. Once we were aboard the flight from Denver to Detroit, the pilot informed us that we needed to go to de-icing prior to lift off. He led us to believe that it would only delay our trip by 10-15 minutes. We sat on tarmac for one hour prior to lift off. I definitely appreciate the safety process of de-icing but I wish the pilot had given a more realistic estimate of time of departure.

Pros: "The whole process from check-in to getting luggage was smooth."
Cons: "Food wasn't great. It wasn't terrible either but I've had better."
Pros: "Food and crew excellent."
Cons: "Boarding process delayed as groups 3-6 all lined up together. No air at seats"
Cons: "Food had little taste. Movies were not that current and selection was sparse"
Pros: "Crew was great!"
Pros: "No leg room"
Pros: "Cabin crew were terrific!"
Cons: "The unfortunate delay of our flight. And the entertainment systems seems to be getting old. What I mean is that it is by todays standard very very slow to switch between menus etc. And in some cases did not display all the menu content."
Pros: "very nice crew"
Cons: "plane was too small and there was 1.5 hour delay departing"
Pros: "They do not have an office or ticket desk in Pudong airport which made early arrival into this airport difficult. No one answered the phone at the Very little English is spoken here"
Pros: "Not much. Crew was good but that is about it."
Cons: "Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment."
Pros: "The full experience"
Pros: "Good boarding.Easy check in."
Cons: "Food! Not appealing. Did not eat more than a few bites."
Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."
Pros: "The flight crew were helpful and friendly"
Cons: "I was forced to miss my second flight because the first airplane malfunctioned"
Cons: "Rather than notify the passengers that our flight would be delayed prior to our arrival at the airport, we waited at the gate for several hours."
Cons: "Our direct flight to Montreal was canceled due to mechanical issues. The rebooking process was discombobulating and we ended up arriving at our destination after the rerouting that was stressful and ensured that we lost a whole day of our vacation time. Our flight back the entertainment system in our seats did not function."
Pros: "put us up in decent hotels gave food vouchers the crew didn't do anything to make it horrible Large selection of movies/tv on board comfiest seats out of all the major airlines I've flown"
Cons: "The flight kept getting delayed bc of mechanical problems, and then eventually cancelled. They rebooked everyone on new flights, but it took an extra stop in Toronto before getting us to Montreal. Once it was rebooked for the morning, it took off a little late. Plus the pretzels they gave us were stale. This was the first of two flights I took this trip that had mechanical issues, so they obviously need to fix their planes better or get new ones, because two Air Canada flights in one day that have mechanical problems leaves me worried that the planes aren't in optimal condition. It took me over 24 hours to get from Tucson, AZ to Montreal, Canada when normal travel takes less than 8 hours including layovers."
Pros: "the pilot did a great job. the crew was nice."
Cons: "It was interesting to me that the plane used for a 4 hour flight (this one) was smaller than a plane used for a 1hr flight. I was uncomfortable the entire time. this was a redeye flight, departing at midnight. the cabin lights stayed on for the first hour making it impossible to dose off. we were given a 'snack' of a disgusting chicken wrap slathered in mayo. it was inedible. oh, and accompanied by a large kitkat bar. I mean. Who came up with this combo? there were no screens, no in flight entertainment unless you wanted to run down your phone battery or rent an ipad for $10. I was truly disappointed."
Pros: "Flignt from Honolulu to Vancouver delayed. Return flight also delayed."
Pros: "We arrived safely."
Cons: "Most uncomfortable plane ride I've ever taken. No food offered at all - everything was by purchase only. No entertainment system at all. Had to stop halfway to refuel."
Pros: "On time"
Cons: "No food or entertainmet."
Pros: "I had an aisle seat"
Cons: "The plane sat on the runway in Denver for over an hour because they couldn't figure out their furling situation. Many people nearly missed connections because of this. The crew never let us get up to go to the bathroom on an international flight because of some small turbulence."
Pros: "Nothing! Unpleasant unhelpful crew at gate, no better onboard, absolutely moist cramped seating ever! Disorganized and late- boarding, departing, waited to disembark at arrival, 25 min before first bag off baggage......dreadful no one cares"
Cons: "Thank you for choosing Air Canada- smiles and goodbyes- where's all that Before you leave? They treat you like problem cattle to be dealt with, you're anonymous and valueless until you leave then they look at you and thank you?! Missing sincerity And service!"
Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"
Cons: "Crew wasn't helpful and attentive, boarding staff in Toronto were blatantly rude to me, I watched as my luggage got handled aggressively, the plane was dirty with old food crumbs and such, my flight to Windsor got cancelled and accomadations were not met sufficiently."
Pros: "Flight attendants"
Cons: "-majority of tvs were shorted out and not working -plane was heavily delayed so didn't make second transfer flight -one attendant gave us wrong directions to next gate at LAX -LAX airport was under heavy construction which delayed gating gate to gate -Customer service offered no options to how to get to San Diego -now we are in debt with a car rental, gas, and having to go back to the airport twice for the baggage -most likely won't be using United Airlines again"
Pros: "Flight was on time. Personal entertainment is very good and crew was great."
Cons: "Boarding is always a bit chaotic with the carry on bags. I am tall, so economy seats are always uncomfortable."
Pros: "The flight was perfect. Stress free. I will definitely get it again."
Pros: "I like that Air Canada provides entertainment and its flight attendants are really good."
Cons: "I rarely fly these partner airlines without experiencing major delays, and the delays are always announced after I have cleared security, forcing me to spend hours at the airport. The claims of "weather" are specious: they don't fly enough planes and they don't properly maintain the planes they do fly."
Pros: "Online booking,boardong pass, alerts"
Pros: "Staff were friendly. My son got to say hello to the pilot as we boarded. It was a smooth flight."
Cons: "It would be nice if there were some vegetarian options for food on the plane. Even a cheese and tomato sandwich would. D good."
Pros: "This flight was so much better than my nice to Montreal flight. It seems like nicer planes should be used for international flights."
Cons: "It'd be nice to have snack and blanket included on a 5 hour flight. We paid $6 for the cheapest blanket ever so my daughter could nap."
Pros: "Crew was nice"
Cons: "Couldn't use in flight entertainment, only half a soda was given"
Pros: "Nothing"
Cons: "Customer service flight rebooking"
Pros: "Nothing"
Cons: "After waiting 30 minutes after our boarding time, I got an email on my phone saying the gate had changed. No one at the current gate knew anything about it and I went to ask but no one could be found. I asked a man sitting behind the gate, who happened to be the pilot, and he also knew nothing about it. Needless to say, the gate changed and absolutely nobody was told about it. 2 hours later, our flight finally took off, and I was thanked by the pilot for getting us to the right gate... At least he provided a little humor to the situation! Plane also wasn't cleaned, pretzels and trash all over the floor."
Cons: "No monitoring of travel route"
Pros: "Clean environment and temperature was pretty constant and comfortable. Staff helpful. The entertainment equipment worked well. This was not the case for for a number of passengers on another carrier's long flight within the past 9 months."
Cons: "There was a nice balance of food, beverages and snacks. However, the food quality was not the same as my previous flight. One meal included mashed potatoes and potato salad and I feel a green salad would have been a better balance. Taste was lacking a bit. Movie choices felt limited. This was "the" trip with the noisy, screaming 2yo sitting directly in front of me. I feel for the child and parents and feel some of the issue was the parent. Crew seemed to mostly ignore the situation. I'm a grandma so usually patient but others around me we clearly annoyed."
Pros: "The process through Heathrow was easy and efficient. Boarding was fairly quick for an international, large flight. The staff were always accommodating and friendly. I was comfortable in the seat, I am a small person but I did notice that the seat was significantly larger than other flights I have been on, and appreciated the entertainment, which had a great selection of movies."
Cons: "The meal served was very nice. The snack served after was a spicy chicken wrap and I really must question the wisdom of serving anything spicy in an enclosed environment with a limited number of toilets."
Pros: "An Air Canada rep over the phone"
Cons: "Gate agent, zero entertainment (and no warning that we should download an app inside airport), poor food, flight attendant wouldn't bring coffee to us (made us go to the back)"
Pros: "Upgrade to premium economy with more legroom. Free movies. Good movie selection. Free checked luggage!"
Cons: "Check-in process at Denver counter rather slow. Gate information at Denver very confusing due to changes and lateness in displaying/announcing information."
Pros: "I enjoyed the entertainment option."
Cons: "Wish there were more choices for new movies."
Pros: "nothing"
Cons: "i booked a flight through kayak going from denver to milan. i showed up at the airport in denver to fly out yeserday only to find out that i was going to frankfurt germany. i am now in munich germany and never made it to milan. i was one of many people i met on the flight that also booked with air canada thinking they were headed to milan. air canada kept trying to put the blame off to my booking company. i don't know who to be ticked off at. please advise."
Pros: "Nothing. Worst airline ever. Air Canada's customer service is AWFUL."
Cons: "My sister is still stuck in Paria trying to get to Casablanca because Qir Canada changed her ticket to Royal Air Maroc in the system but failed to pay the ticket!! She's been traveling from Seattle to Casablanca for three days and she's still not here yet! And I'm going into labor very soon!!"
Pros: "Great crew. Nice airline."
Cons: "Both flights were over 30 minutes late. Otherwise they were just fine."
Pros: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"
Pros: "Nothing."
Cons: "The flight attendants on this flight did NOT do their job. If they are there to ensure a safe environment for the people on board, they completely missed the boat. I was in row 45. Two families were on board with their 4 very young children. For the entire 8 hour flight, 3 of these children disrupted the entire section of the plane. They continuously played in the aisles, stood in the seats, kept their seat belts unbuckled, threw objects, and one blasted his iPad at maximum volume. When I asked one flight attendant to ask the family to get the child to lower the volume on his iPad (it was 4am; people were either using their ear buds, or had their screens turned off), they complied with the request for 30 minutes, then resumed at full throttle. I can honestly say, it was one of the worst flights I have ever experienced in 57 years."
Cons: "This was the worse travel experience I have ever had. The crew was rude and gave wrong information that caused me to almost miss my flight. My ticket in the end ending costing me over $600 for all the additional charges. It was ridiculous. Among other things. I will never fly with them again."
Pros: "There was entertainment on board although it was very limited. All of the crew were very helpful and professional."
Pros: "Because of a plane malfunction I ended up meeting 3 very good friends. The flight was okay"
Pros: "crew"
Cons: "delayed due to computer malfunction, food awful, missed my connection, had to wait for 6 hours"
Pros: "Na"
Cons: "Na"
Pros: "The movies"
Cons: "Why are stews so rude."
Cons: "Wifi would be nice on the smaller flights"
Cons: "bad"
Pros: "The reps at customer service were very nice and helpful. Kudos to them"
Cons: "I missed my flight to Grand Junction the night before because my plane from Dulles was delayed. So, consequently I had to spend the night in Denver. I was not pleased with that at all."
Pros: "Crew was amazing. Movies were cool. Easy flight for a first time flyer."
Cons: "Nothing. It was great."
Cons: "Flight was delayed"
Cons: "Delayed 2+ hours"
Cons: "I had a very large man in the middle seat next to me. I was in the window seat. He leaked over into my seat which made it very uncomfortable especially when he fell asleep. I know the airlines can't do anything about this but he should pay for a larger seat."
Cons: "Delayed flight"
Pros: "Crew was very friendly and professional."
Cons: "Pillow for back support would be nice. More Japanese food choices would be nice also."
Cons: "Flight was delayed 1.5 hours coming into Denver due to an oil leak they fixed at the last airport. Turned out the leak wasn't fixed. Took an hour to get a mechanic to look at it and then they cancelled the flight. United's partner had no other planes in Denver so we had to sleep there after sitting in the airport for almost 4 hours."
Cons: "I didn't go on my trip. My course in SF was cancelled and United would n't refund my money or change the dates for my trips because of there basic economy package. They have 3 different economy packages and the economy basic doesn't get refunds and you can't change the flights if needed. It feels like they are banking on increasing there ROI with this basic economy ticket which is 40 -60 dollars cheaper than the next economy package. Intuitively they know people will pick that, but if something comes up the customer is screwed."
Pros: "Wifi wasn't working. People were loud and rambunctious."
Cons: "The boarding process with United is always a mess. Lines way longer than necessary and spilling into the main walk area of the airport."
Pros: "crew was SO pleasant! respectful of sleeping passengers came around with snacks and drinks then came around a bit later with coffee and water in case anyone needed a refill or missed it the first time"
Pros: "I liked the customer service wfrom the woman who helped us find a way with patience to get a working card to get our luggage checked in. I liked the customer service on the flight they were attentive and friendly."
Cons: "The options to pay baggage with one card is rough on the average traveler, the baggage charges cost as much tickets!"
Pros: "Nice seats, very helpful staff at ticketing and nice crew"
Cons: "Reservation was deleted so check in took a very long time and my seat (reserved weeks in advance) on the long international flight was reassigned to a very undesirable location."
Pros: "Staff was friendly"
Cons: "United has a system glitch and we were delayed. I got in around 1 am instead of 11 pm. I decide to order a glass of wine and since they don’t give receipts. I found out i was charged for 2 glasses instead of one. To top it off the co-worker i was traveling with didn’t get charged due to the inconvenience and delay. i travel a lot with United (higher status than him) and would have liked that offer (and not get charged one i didn’t order) being a mileage plus and credit card holder. I did go on line and ask for a credit and they did make it right and give me a credit."
Pros: "Nothing unusual"
Cons: "Nothing unusual"
Pros: "Nothing"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."
Pros: "Crew did a great job. Air China had much better food service."
Cons: "Seats two small, not enough room to stretch your legs. Bathroom to small. Designed for people less than 150lbs, and 5'-6" in height Not comfortable for people over 6' tall."
Cons: "Delayed flight due to "low air in tire" made me miss my connection to Iceland and ruined my very expensive vacation."
Cons: "Customer service for united is terrible and the attendants were rude while we were delayed for 2 hours on the tarmac"
Pros: "Seat 7 A on this type of aircraft - and United's configuration - had the most leg room and space, esp. when the seat next to you is empty. The flight crew was friendly and great!"
Cons: "Boarding gates/ area in Denver airport for these small aircraft was almost as bad as a bus station! Crowded and most cramped/ uncomfortable. Denver United staff at customer service center was most unhelpful, unsympathetic and dismissive about the fact that in spite of a flight delay that completely their fault (no weather delay), which made me miss the memorial service for my friend's daughter - my main purpose for visiting Cincinnati - they refused to even give me a patient hearing much less consider my request to try and put me on a different flight!"
Cons: "I had flown from Honolulu to Denver arriving at 6:30 am this morning having paid $25 for a checked bag. So had to get luggage and turn right around to check-in for Denver to Cedar Rapids and pay another $25 with the same airline because I wasn't able to check all the way through! So I feel I was charged double"
Pros: "The flight crew and the cabin crew were professional and efficient and friendly. The ginger ale kept me from getting nauseous during the turbulent approach."
Cons: "I realize that the airline doesn't have much control over screaming babies, but the reality is, my flight experience was significantly worse because of one, a couple rows back, who kept screaming at the top of their voice for most of the flight. While everyone was seating themselves, my fellow rowmates asked me to exchange my window seat for an aisle seat, so that grandmother, mother, and daughter could sit together. That put me two rows closer to that screaming baby. I came prepared to watch a movie with my phone and new noise canceling headphones, and then discovered the United Wi-Fi didn't offer movies on that flight, the same aircraft type and route as when I was able to watch a movie that way, earlier this year. I didn't find a way to connect my Bluetooth headphones to the plane's entertainment system, and I'm also disappointed in myself, to have to say, it took me far too long, to figure out that I needed to interact with the screen in front of me, through the control pad under my elbow on the armrest. By that time, there wasn't enough time left in the flight, to start a movie. So, I just played music stored on my phone, which helped mask the baby screams."
Pros: "Nothing"
Cons: "Being stuck in plane on tarmac was horrifying. Knowing I was going to miss my connection and that I couldn't do anything was awful. May never use United Airlines again."
Pros: "New nicer attitude from crew"
Cons: "Small seats"
Pros: "The flight"
Cons: "The time"
Pros: "The Captain kept us apprised of the delays in our flight."
Cons: "How the Denver airport has their gates set up for 77/78/79 and others, having to walk down stairs? then down a long hallway to go out on the tarmac to board the plane, then when having to deplane, repeat what we had just done in reverse, some customers were traveling with small children/babies, no offer to help these people were made, except to tell them they could use the elevator. Thought it was ridiculous that we had to go all the way to original gate when we were told we would be loading again on the gate next to the one we just came in from."
Pros: "Staff very nice, plane left late but made up time."
Cons: "Seat was not comfortable and did not recline enough to provide for a nap."
Pros: "I like everything United does for the most part. It is a clean., well-run business, with friendly people."
Cons: "I am 6 foot 6 and I am a teacher who cannot always afford business class. The economy seats cause people to literally laugh when they see me try to sit in one. The person in front of my cannot lean back unless I spread eagle and take the space of the person next to me. Generally, I request an open exit row seat, which they now charge 100 dollars for. I don't think I should get free everything because I am tall, but it's not like I am fat, I have no choice in the matter and flying tends to be tortuous."
Pros: "Everyone was friendly, flight was on time checking in at kiosk was very efficient no complaints . I would recommend Kayak and United to friends and family"
Pros: "I liked the power outlets that were available, as well as the USB! I have trouble sleeping on flights, but the great options for the in flight entertainment made it more than bearable. I will always choose to fly United now."
Pros: "When I was flying red eye they made it really easy to sleep. Lots of room excellent."
Cons: "I was too drunk and my ears felt like they were bleeding but the staff was really nice"
Cons: "I think a whole can of soda is the least that should be provided for any flight."
Pros: "Nothing to like. 6:00pm flight delayed and kept rescheduling takeoff. Boarded plane about midnight and after ninety plus minutes we were made to deplane because current crew was over their allotted airtime. Kept on plane awaiting a new crew but they couldn't get them so flight cancelled. Attendants told us we would be compensated for cancellation. A big airline like united should have a better grasp on scheduling flight crews and stand bys available instead of putting us through this hell. No hotels available so we all had to stay overnight in uncomfortable chairs with many sleeping on floors. I felt bad for myself as a 69 ur old woman with some health issues but felt even worse for the parents flying with little toddlers who just wanted to go home. The day of my flight Denver had 8" of snow that stopped by 9am yet I couldn't get a flight out till the following evening. Psp to Denver to Newark should have taken six hours but took me over 38 hrs of travel time. Denver should be used to snow and 8" shouldn't cause such extreme disruption at that airport. And united needs to better coordinate its flight schedules and working crews. I will be contacting customer service regarding compensation as cancelled flight was due to company musmagent. Finally it would have been nice if united opened its club to the travelers who couldn't get hotels. Sitting in a comfortable place would have been so much better especially to the elderly and small children traveling. Thank you"
Pros: "I made it home"
Cons: "When I got to the ticket counter my reservations had been canceled by united. Worst part is the flight is now completely booked. I was lucky enough to make the flight thanks to a late flight from vegas where 7 people were connecting from but it was pretty stressful to walk up to the counter to be told the reservation you have had for 2 months was no longer reserved. This was one of the rudest staffed planes I've been on. These guys aren't over worked. I don't know why they can be so hateful. I loved united but this experience has left a sour taste in my mouth. It all worked out in the end, but I still can't follow why my flight reservation was canceled without me being notified. I shouldn't find something like that out when I get to the airport with my luggage in my hand."
Pros: "The crew members at the gate were friendly and courteous. The plane was clean and pretty new looking. The onboard crew were fine, for all the dealings I had with them. Our bags, which were gate checked, arrived with us and intact."
Cons: "The seats are narrow, and I'm not a wide person. They are crowded in every direction. The airline(s) crowds more people into limited space, then charges people to check baggage, yet they seem surprised and ill-equipped to deal with the lack of space for carryon bags, begging people to gate check before boarding, then scolding the last people who board for bringing their bags to their seats, expecting to find a place in the overhead bins for them. They charge for snacks other than 2 oz. of pretzels. If this is considered part of the hospitality industry, the company gets a failing grade. The individual staff do the best they can."
Pros: "Comfortable seats and lots of leg room. I was not crowded at all. It was so nice to not feel cramped and to have plenty of room around me. It was one of the most comfortable flights I have experienced in years!"
Pros: "Cheaper"
Cons: "Long boarding and delayed flight, lots of walking"
Pros: "It got me home."
Cons: "The flight was delayed by more than two hours. I had a two hour drive after which got me in bed at 4:30 AM instead of 1:00 AM. Had to work that day which made it hard to function. Usually great, but was disappointed they didn't offer anything to us for such an inconvenience."
Cons: "Our seats and boarding passes were given to two other people! How can someone else board a plane with our names on the boarding passes?!"
Pros: "Staff was friendly"
Cons: "A little hot on the flight."
Pros: "The airplane was new and clean"
Cons: "The pre-boarding staff were rude and not helpful. I had requested an aisle seat when I booked my flight. Somewhere along the line, my seat was changed to a middle seat. When I asked the staff if I could switch to an aisle seat to help accommodate my sciatica, they told me, "sorry, we can't help you, you'll just have to ask another passenger." Neither crew member was willing to work with me or hear my concerns. So much for flying the friendly skies...well I guess we were still on land, so may that principle had not yet taken effect."
Pros: "The plane itself was beautiful and seating very roomy."
Cons: "Mechanicall problem was nothing more than routine maintenance according to the pilot. After sitting on the plane 2 hrs with continued further delays I opted off and took a different flight which arrived 3 hrs later than originally booked. Very very annoying. At least I didn't miss my connection like many many passengers on board."
Pros: "Crew was friendly. It was a long flight, so glad that came around in between drink services to offer water."
Cons: "Not that much content on the entertainment device, several movies were only playing in Japanese and no option to change to English. My device kept shutting off at random times despite having full battery."
Pros: "As above"
Cons: "As above"
Cons: "I did not like having to check my carry on after all. I was told the overheads were full so I could get it in Baggage after the trip. For health reasons I did not want the trip to baggage and I did not want to risk my bag being lost. I drive 3 hrs o the airport and I did not want to drive back or wait 3 days for a lost bag to be sent to me as I have before. The person at the gate was rude when I said you won't lose my luggage will you? he said Probably. I said really, and he said well you did ask."
Cons: "Took me four days to get to my final destination due to flight cancellations and delays with absolutely zero customer service. Had to jump through hoops to get on my final connecting flight."
