Cons: "A quick drink service would have been nice, it was provided on the same flight going the opposite direction"

Cons: "100% as always.. delta has never disappointed! Keep up the good work guys"

Pros: "The crews were super accommodating and my seat was so comfortable I actually feel asleep which is something I have never done on a plane before."
Cons: "Load the plane from back to front. It makes sense as people leave the plane from front to back"

Pros: "Crew was friendly and efficient."

Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."

Pros: "Flight was delayed for more than 3 hours."
Cons: "Could have left on or close to schedule."

Pros: "Lovely crew. The food was tasty."
Cons: "It would’ve been nice to make up some flight time in the air from the 4 hour delay and multiple gate changes that were all announced too late to delay a trip to the airport :("

Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."

Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."

Cons: "Seats are so small. Flight was delayed."

Cons: "Couldn't believe the flight attendant walked around with a tray of snacks and bananas. When I asked for the banana, she said, "Oh I'm sorry, those are for First Class only". Really?"

Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

Pros: "Professional appearance of flight staff accommodating and sincete"

Cons: "The flight from. JFK to Barcelona was delayed as well. Their computers were down in Atlanta. So everyone had to have their name hand typed into a computer when boarding. Then the pilot said that our bags are usually weighed and computerized for even distribution on the plane. That system was also down, so we sat on the runway waiting for that problem to be fixed. When we arrived at Barcelona, I unpacked and discovered a jacket and pants in my luggage were wet. The only place that could have happened was at JfK during their rain storm and the luggage weight issue."

Pros: "The flight crew were awesome"
Cons: "Not exactly the flight but the attendant white lady in Atlanta at the gate needs to sharpen her customer service skills, a bit obvious on who she prefers to deal with, as a foreigner and over 25 years of experience in dealing with the public, I felt the indifference. I frequently fly and my choice of airline is delta, this by far has been the only dissappointnent. Please do make sure this gets to the person in charge."

Pros: "Food and entertainment was good"
Cons: "The bathroom I used was disgusting."

Pros: "Boarding, friendliness of staff"

Pros: "Everything was easy and smooth."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Cons: "Was unclear which zone was boarding. Legroom was comprised when passenger in immediate row ahead reclined seat early in flight."

Cons: "Engine problems-2 hour delay"

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Copilot was an hour late, inexplicably"

Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "Most comfortable flight I have taken in some time. Spacious seat, power, good entertaiment, attentive flight crew. On time. Not usually a Delta flier, but times and destination made Delta the choice. Turns out a great choice."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Pros: "Staff was courteous, flight uneventful but that's a good thing!"
Cons: "Long flight, difficult to sit that long (3 hrs plus)"

Pros: "It's a nice, comfortable flight with plenty of entertainment options."
Cons: "The coffee on board is lousy, but I'm not sure that is much of a surprise."

Pros: "Great,I loved it!"

Pros: "Food, crew, boarding"
Cons: "I had a screen in front of me that did not work. It was annoying. Fix it."

Pros: "The moviea"
Cons: "The time of night"

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "Entertainment options"

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Pros: "Was able to get on a flight after ours was cancelled. Delta was in scramble mode and their gate staff worked hard ot deal with a frustrated flying populaiton"
Cons: "After paying for first class round trip airfare, we were given seats in coach in the rear of the plane, in spite of empty seats (plenty of them) in first class and economy comfort."

Pros: "Delta Comfort+"
Cons: "Boarding In-flight entertainment Meal Service"

Pros: "Overall.. It was Ok exept for the boarding experience described bellow."
Cons: "I bought the tickets through a third party website. Therefore, our seats were not assigned until the last minute, and once they were assigned, they were published in a screen with our initials. This practice was discriminatory and violateed our rights for privacy, We even felt that it could put our security in risk. I believe that one thing is not to allow clients to choose seats in advace because they bought the ticket through a third party website, and another thing is to discriminate an treat those clients as "second class" people. When I asked the person in the counter for the reasons behind this practice, she could only say it was Delta's policy to do it that way. In that sense I was very surprised with the practice because i bought an Airfrance ticket (not a Delta one) and I had travelled before in both airlines (Airfrance and Delta) and I had never experienced a situation like the one described. I strongly believe that Delta needs to review this practice."

Pros: "Flight attendants were lovely"
Cons: "Nothing"

Pros: "Excellent customer service. That doesn't seem to happen too often with airlines. Delta has been outstanding."
Cons: "No complaints."

Pros: "Flight took off on time and arrived about 30 minutes early."

Pros: "on time travel care in treating my visitors from Kenya Africa"

Pros: "It was on time and got me where I needed to go."
Cons: "The crew often bashed my wife's elbow with their trolleys. I am 6'2" and I could not sit with my legs straight in front of me. There is no leg room and the seats do not recline very far. The food was repulsive. They ran out of vegetarian options (my wife is a vegetarian) and what we did eat turned our stomachs."

Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Cons: "Flight was delayed"

Pros: "everything"

Pros: "The service was excellent along with the flight being very comfortable."
Cons: "A little more options in entertainment in the hindi language would be much better for people who do not like to watch English entertainment. Along with that free wifi would be kind of good to have for people who need to work on the flight or check out important emails."

Pros: "Great service. everything was on time, or early. overall pleasant experience."

Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."

Pros: "Slept like a baby with no interruptions."

Cons: "Limited choice of types of meal - no vegetarian option."

Cons: "I was unable to make a pre-flight meal selection. Lufthansa customer service indicated I would have vegan options on board. Not the case."

Pros: "The crew was very friendly and polite. The airplane was clean. The boarding was quick and easy. The entertainment was varied and enjoyable."
Cons: "It wasn't an issue on my flight since there were empty seats in my row, but I don't enjoy the spacing provided for personal items on the floor under the seat in front you. For four seats there are three sections; so, you can hope that someone doesn't need any space or else you have to decide how to awkwardly split it up."

Pros: "At least Lufthansa has a little bit more leg room."

Pros: "See above"
Cons: "See above"

Pros: "The best in-flight service I have ever had on the Lufthansa flight from Denver to Munic!"

Pros: "United is a good partner to Lufthansa. I like United. It was a quick flight, but a good one."

Pros: "Everything"

Pros: "This flight was fine. About as comfortable as I expected."
Cons: "I sat next to a man who had a vape pen and a can of chew with him. So the entire nine hours I spent smelling his mouth tobacco and I could do nothing about it. It was disgusting."

Cons: "Couldn't sleep because of seating."

Pros: "The direction"
Cons: "One flight attendant was rude to me"

Pros: "The food was very good. The service, the preciseness."
Cons: "I didn't like the entertainment, there should me more options for movies in English and Arabic."

Pros: "Nothing"
Cons: "They checked everyone’s carry on bags, which made the boarding process incredible slow, then they made you stand on a bus until it was full, to drive to the plane to walk up stairs in the rain. I kept my bag for 20 hours, flying from Vancouver to Calgary to London and before my flight to Madrid. They didn’t care that I said I didn’t want to give it up or that I had to make a connection. Madrid’s airport is notorious for have slow baggage handling, so they are making me wait. I packed for 2 weeks in a carry on and back pack to avoid checking luggage. I am disappointed."

Cons: "If we would have made the flight, unfortunately the flight from Malaga was delayed and caused us to miss the flight from Madrid to Chicago, I’m now sitting in Boston waiting for a flight to Chicago and will probably miss the last bus to Milwaukee"

Pros: "The seats were comfortable"
Cons: "Everything was ok"

Pros: "Nothing, total stress making us re-check our baggage"
Cons: "British AIrways could have checked our bags through from Denver to Paris....after all it was British Airways to British Airways, but they made us check only to London, retrieve bags carry them to another terminal recheck them for what Simon the BA ticket writer was nothing but pure error by British"

Pros: "The big snow storm cause a 6 hours delay from JFK to MAD, which made me missed my connection flight. Iberia didn't honor its responsibility to find me a connection flight and had no idea where my luggage was. I ended up paying for a train ticket with Renfe from MAD to VLC."
Cons: "It is insane that Iberia didn't help me at all. Iberia should honor its responsibility to ensure the customer have a connection flight when there was a delay due to weather. They were not well trained to locate my luggage, and help me finding an alternative solution, i.e. Renfe train to MAD to VLC."

Pros: "The departures and arrivals were on time."

Cons: "Our flight was delayed causing us to take a red eye, missing our connection,long layover, missed our hotel for the night, thripled our time in transit. The worst travel experience I have had."

Cons: "We love everything was our first time and was excellent"

Pros: "The crew was very friendly. Lots of movie options. I got a voucher due to the delay."
Cons: "The delay was a bit of a bummer and it would have been nice to be compensated with more than a voucher that couldn't be used in LHR because it was in USD. I also would have liked to been told they were still planning on serving dinner despite the midnight departure; I fell asleep because they turned off the cabin lights and I assumed the meals had shifted, but instead I missed out of my dinner. Lastly, I am quite petite and still struggled with legroom."

Pros: "Orderly boarding and disembarkation."
Cons: "This airline is one of the worst in Europe, for the simple reason of putting short-term profits ahead of decent treatment of the customer. My flight across the Atlantic was 4 hours late, and BA refused to put me on the next available to Prague, even though the lateness forced me to miss the BA flight I have been booked on. Their reason referred to a technicality in the booking procedure, but actually BA has put in place "policies" aimed at their financial advantage, over and above reasonable treatment of the customer. BA's refusal to rebook me cost me a lot of inconvenience (3 hours on the phone, for one thing) plus about $150 (I am taking another route to Prague); BA was then able to sell both my original seat and an extra seat on the next flight from Heathrow to Prague. I will never fly BA again in my life if I can help it."

Cons: "One of the worst experience I’ve had, if not the worst. Lack of communication between flight attendants at gate was the main reason for missing our flight, after 2 delays from the previous flight. When we got to the gate they closed it at that moment, earlier than it should have. A Mr. Fenney, person in charge at the gate, didn’t help much. Just went through the motion and as slow as possible trying to help us. It seemed he just wanted to pretend he was helping us. Worse was his attitude when telling is the gate has already closed, didn’t do anything to help us, nothing at all. We had to literally get information out of him. We then went to customer service were the same thing happened, a lack of care that we missed our flight due to things out of our control. Even to the point where the agent told us “be sure to be there on time this time”, like if it was our fault we missed it (we told her the details of our situation). Till this point they don’t seem to care. They left about 15 people, that i know of, hanging. If they had better comunication between gates and waited a miserably 5 more minutes (although they closed the gate earlier then they should have) everyone would have made it. Throughout the whole process we noticed that american airlines employees did not care that many on that first flight had connection flights. They were just going through the motion, slowly while all of us were a bit desperate knowing that the layover time was going to be very close."

Pros: "Courtesy of tge british airway staff"

Pros: "The crew was very nice"

Cons: "Flight was cancelled with no notice.or explanation Stuck at Heathrow no alternatives available. We are a party of 7 3 young children and 1 disabled passenger . Now one of us flys tomorrow via Madrid, and palma before mahon. All others fly Sunday via Barcelona. Hol ruined disgrace"

Pros: "No entertainment and no vegetarian selections in the menu unless you book in advance again the plane was dirty"

Cons: "I had a connecting flight from London to Madrid. Not only was the flight to London late over an hour, because of the security check point and liquid quantity confusion I was late to the connecting flight to Madrid and had to take a later flight which made me late to my meeting but on top of that I had to get rid of some of my stuff because it was over my limit on liquids. Very frustrating!"

Pros: "Service, food, safety video"
Cons: "Delayed flight"

Cons: "no complementary drinks, coffee, snack, nothing? not very hospitable"

Pros: "Very courteous attendants"
Cons: "All good"

Pros: "The food was better than expected and the crew did everything they could to keep us comfortable"

Pros: "not much"
Cons: "5.5 hours delay"

Pros: "Just so comfortable and friendly. I'll fly them again next time!"
Cons: "Nothing."

Pros: "Because of a delay in the first leg of my trip, I missed my connection in London. However, I was placed on the next available flight without much hassle, although I did arrive later than the group I was meeting up with."

Pros: "I loved the legroom in the emergency seat I had and the service was top notch. The food and food choices was also really nice and the wine served with dinner was great."
Cons: "Overall loved my emergency row seat the only negative for my particular seat was once the rest of my row was filled in and the 2 seats in front of me it made it impossible to get out of the seat and stand up unless I could had the person sitting in front of me get out of his seat."

Cons: "I was not allowed to check in online, so I had to go to the airport early to check in. Despite purchasing my flight months prior, and arriving at the airport with plenty of time to to check in, I was told that I was going to be bumped from my flight because it was overbooked, which would mean that I would miss my international connection. After waiting for everyone else to board on a tiny flight, there suddenly was a seat available and they let me board, but they managed to not put my bag on the flight, which means I have no luggage. Lastly, despite checking in more than 7 hours ahead of time for the international flight, I was given a middle seat and was told that I would have to pay $40 if I wanted to switch to an aisle/window. The middle seat was cramped and uncomfortable, particularly for 8 hours (after 7 hours of connections and waiting in airports). UGH."

Pros: "The stuff was very friendly"
Cons: "Very uncomfortable seats"

Pros: "Nothing"
Cons: "Old plane, flight attendants boardering in rude, very poor food (!), de-plane via steps to the tarmac and at least 7 coaches at Heathrow (an aged 747, so it took nearly an hour!)"

Pros: "Everyone was awesome"
Cons: "The staff was awesome"

Cons: "We purchased upgrades to an exit row seat because my knee locks up when cooped up for that long. They changed the plane and I understand that happens but they denied our refund request with 7 days deadline to re-request. So now we have to spend valuable vacation time dealing with their incompetency"

Cons: "Paying for a soda!"

Pros: "No turbulence!!!"

Pros: "For economy class it was good seats (bulkhead), the crew were nice, and the food was good."
Cons: "The tiny screens for movies were awful. Worst of all, the horribly loud voices that nearly break eardrums when the crew comes on during the flight was both painful and annoying."

Pros: "Food awful no entertainment"

Cons: "Delayed"

Pros: "Easy and quick boarding. Dinner tasty, but it is hard to cut a fillet steak without hitting the next passenger in the elbow"
Cons: "Only one check-in agent running all desks including bag drop - long wait. 19 year-old 747 had narrow seats in premium economy, uncomfortable and too much body contact with adjacent passengers. Outbound to SFO in an Airbus 380 had sparkling wine pre-take off, hot towels twice, this DEN-LHR flight only had juice or water on offer (crew said "don't serve that on this route") no hot towels, crew's objective seemed to be get around cabin in one go and leave Pax to it Breakfast was abysmal, soft-pretzel roll, no juice or water served, just indifferent coffee"

Pros: "Usual fantastic standard of service"
Cons: "Shabby baggage reclaim service at LHR with staff ignoring priority baggage"

Pros: "It all went smoothly and was on time"

Pros: "didnt remember a single thing from this flight because I was passed out from exhaustion after not being able to sleep at all on the previous flight.... this flight was run by iberia, and the seats were delightfully simple compared to the atrocity in the BA world traveller section"

Pros: "ORD -> MAD The flight was on time, it boarded on time, it took off only a few minutes late (you can blame that on incredibly crowded ORD). It landed, on time, to an empty terminal. The plane itself was new, very clean, and very well kept. The crew was friendly and spoke a wide variety of languages, including English, French, and of course Spanish. They had no issue with Latin American Spanish or European Spanish accents, which is a concern for some. Overall the flight got me to my destination on time, in one piece, and without breaking the bank."
Cons: "The seats, oh the dreaded seats. In economy class the seats are the most uncomfortable thing you can sit on for 8 hours. If they replaced them with plastic folding lawn chairs, you would have a better time. But that is what you get for flying coach."

Pros: "When the flight was delayed and I missed my connection, the crew had a new ticket for me by the time we landed."

Pros: "Yes made sure mask was in place"
Cons: "No"

Cons: "Overbooked and crowded, on a Sunday."

Pros: "Nothing extraordinary, just solid positive experience from checking in on my phone thtough disembarking"
Cons: "I like the convenience of the built-in multifunctional screens (like on Alaska flights) that AA are lacking"

Pros: "Great price!"
Cons: "More food."

Cons: "Not lost my bag!"

Cons: "I never made it... I had a trip interruption and got stuck in Chicago and would of had to wait another full 24hrs to take the flight to Denver. tired and nauseated after being all day at the airport that at midnight, i knew that I couldn't hold off till the next evening, took the next flight back."

Cons: "The flight was delayed which caused us to miss our flight in London our family was delayed for 12 hours"

Cons: "Checked baggage untimely, causing me to miss the train"

Cons: "Kept the lights on for too long serving dinner. Forgot to serve the middle section beverages during breakfast."

En el aeropuerto de Denver habia solo dos personas en el securty check por lo cual la demora fue involuntaria en mi caso. Cuando estoy haciendo la fila para ingresar al avion (esyando en la misma cola antes de ingresar) me informanque no podre embarcar..(claro ya habia designado mi billete a otras personas. pesima atencion y pesimna experiencia con los empleados de ese vuelo. Denver a Miami"

Cons: "I will never fly AA again - see below"

Pros: "On time, friendly and helpful staff at airport and on aircraft"
Cons: "Nothing"

Cons: "I had a severe back injury in Denver and they were unable to move my flight up a day to get home and see a doctor. A good friend had to buy me a new flight with his airline miles so that I could get home to relive my pain. I'll never fly American again because of this complete lack of compassion and care for their customer."

Pros: "Nothing."
Cons: "The entertainment screen for seat did not work. A crew member indicated that he would try to fix it, but he never reappeared and nothing was done to alleviate the problem. They could not have cared less."

Pros: "Friendly service"
Cons: "Snacks"

Pros: "how easy it was to purchase ticket on kayak."
Cons: "Being charged for my checked bag unexpectedly at check in."

Pros: "Space security manners"

Pros: "The crew was extremely kind and selection of food/drinks was excellent."

Pros: "On time Easy and no issues"

Pros: "The entertainment was nice!"
Cons: "The seats were not comfortable"

Pros: "La atención del crew en el avión"
Cons: "Aunque Sean viajes cortos ofrecer almenos bebidas"

Pros: "Not much. There was one flight attendant that seemed pleasant but I wouldn’t know for sure since the attendants ignored all passengers except for those who had preordered their meals."
Cons: "It was extremely frustrating that there was no kiosk available when checking in. I did not have a bag to check, yet I waited on a ridiculously long line to check in for my flight. The people working the desk at the gate were slow and unpleasant. Service on plane was terrible."

Pros: "One crew guy was really nice. I had bruised my leg and he gave me ice and checked in on me."
Cons: "Vueling/Iberia lost my luggage."

Pros: "Fine flight once we were in the air."
Cons: "There were NO SIGNS saying it was a level flight, not Iberia. No one at Iberia check in desk etc. We eventually figured it out after a while. In general Iberia and level are short staffed and unorganized. If you're willing to deal with this, it's an affordable option and they'll get you from A to B."

Pros: "Smooth flight"
Cons: "It was delayed"

Pros: "Nothing"
Cons: "I checked in online and paid for a checked piece of baggage, never received the boarding pass, so when I arrived to the airport to drop off the luggage and wait for boarding, the machines didn't recognize my ticket locator and I had to stand in line for almost 2 hours (missed my flight)…"

Cons: "They had problem with plane and had to change it. Then we havd the proper allowed carry on and they had no space.... short thrip of a little over an hour but the getting to leave was the worse...."

Cons: "Crew was friendly to some people and completely ignored others, or at least me. Not sure if they knew Passenger status or what."

Pros: "Entertainment was ok, had holl rodarte options and good variety"
Cons: "Seats are hard, no leg space, no elbow space, the upright is 90degrees. The crew is not helpful, to the point and act like they are doing you a favor by being there. In one instance the attendant told a passenger "you can move your bag, or I will move it for you." To another passenger, without prev"

Pros: "nothing"
Cons: "It should have departed on time. It departed 50 minutes later than the original time."

Pros: "Arrived at destination"
Cons: "Left an hour and a half late due to mechanical problems. This also disrupted in flight entertainment system. Got to destination"

Cons: "The crew is not nice and rude. The checkin counter didnt allow me to have overweight of 300 grams. Ridiculous. At some areas of the plan the air conditioning doesn't work well"

Pros: "Clean and fairly new aircraft. Good flight"
Cons: "Ground staff more helpful"

Pros: "Don’t feel fully informed of what is going on. Had overhead bin opened and seat reclined during takeoff."

Pros: "Gfggfgggvfvfvfgfdhygtgdhfffdcdcf"
Cons: "Gbhbhfhyhyugfrrfffffgggffccxccccvvgfcvgvggbbvvgcvvv. B"

Pros: "It was a direct flight"
Cons: "Ticket had no info on baggage allowance. Got charged $55 for one piece. Website has glitches that would not save passport info. Flight attendant did nothing. Did not ask people to have their seats upright during landing. No food or even water for a 7 hour flight unless you pay. Seat uncomfortable. Horrible experience."

Pros: "On time, clean airplane, smooth, good flight overall"
Cons: "No entertainment or food on board. Not even drinking water"

Pros: "Nothing"
Cons: "Delayed flight from Milan to Barcelona caused us to miss the connecting flight and we were stuck in Spain for the night. Will not get back to US for another 2 days."

Pros: "Nothing -- though seat was okay. No leg room, but it reclined a little, and had those foldable headrests."
Cons: "The boarding was supposed to be by zone, but was just a mad rush. They served no food, not even for money. There was an onscreen ordering option, but for the entire flight it said "this service is temporarily closed". They didn't have a beverage cart. Not even water or coffee. I couldn't even get a cup of water to swallow some ibuprofen and an allergy pill (somebody brought a companion cat, I suspect, quite near to me). No food or water on an international flight across the Atlantic??? You've got to be kidding me -- that's gotta be close to illegal, not providing any means of hydration. But it's certainly cheap, mean, and unacceptable. Pathetic, too."

Pros: "Nothing"
Cons: "Delays an chaos"

Pros: "Price"
Cons: "N/a"

Cons: "We had to walk onto the tarmac and climb up stairs to board the plane carrying our luggage and small child."

Pros: "Once I understood how it worked it was a breeze"
Cons: "Made more than four different lines before 1 understanding Iberia worker helped us out. Was told that that wasn’t the correct line and sent to another. The next place the same for more than 3 times. Then finally, Raquel, LISTENED, and away we went."

Cons: "This is my second time flying with this airline and it’s 40 mins late leaving again! Poor reliability and flying at night with my young son. I did not want to arrive an additional 45mins later in a city that can be dangerous"

Pros: "Some good films to watch"
Cons: "Terrible seats mediocre food our tickets said Iberia but it was actually its low-cost version Level"

Cons: "Layovers are what makes the flight bad."

Cons: "The plan was too small."

Pros: "The cool thing about this airline is that it’s dirt cheap to get from Oakland to Barcelona!! I will say tho, you do get what you pay. We purchased the most basic flight and that’s really what it was. Tight leg room and lots of people. If you’re over 5’5 I HIGHLY RECOMMEND getting extra leg room if it’s available. Aside from that. The flight was cool and the staff was nice!"

Pros: "Good organization and time on flight."
Cons: "In 10 hours never offered water."

Pros: "Airport was spacious and gate area/aircraft clean"
Cons: "Captain made. Or announcement other than twice very loudly to announce take off/landing to crew. Woke people up."

Cons: "Disorganized boarding"

Cons: "Extremely uncomfortable and no food or drinks with basic fares (have to wait for separate paid cart). Watched a sick woman be told to go away when she asked for water."

Pros: "Our flight was subcontracted through another airline, Level, so my comments are related to Level."
Cons: "I called the airline a week before our departure regarding the baggage fee. I was assured the fee was included in the price. However, at the time of check in, I was charged a $55 checked bag fee."

Pros: "Nice crew and good landing"
Cons: "We paid extra to sit in Economy * I am 6-3, wife 5-4 and neither had any leg room We were sitting in 2 seats by themselves. It was an endurance contest to make it through the flight. I will never fly Iberian Airlines again. It was terrible!!!"

Pros: "Nothing"
Cons: "Flight from Iberia, operated by AA and finaly no flight!!!!!"

Pros: "We flew like we were on a business class service, excellent crew, nice offer of meals, comfortable seats and flawless journey. If you are given the chance to upgrade to Premium, do it."
Cons: "Short selection of subtitles for videos. Catalogue not bad but could be improved"

Cons: "Slow service by the flight attendants; poorly stocked food options. perhaps it’s a European thing with budget airlines but to pay for water is unacceptable."

Pros: "Quick boarding."
Cons: "No movies or videos. Children crying and screaming."

Cons: "I got to airport and it wasn't operated by iberia as I had been told. Instead one part was operated by American Airlines in the second part of my flight is operated by British Airways which involved a 30 minute walk and train ride through the airport"

Pros: "Professional kind and helpfull crew Punctual departure and arrival on time"
Cons: "No free headphones available and no games on personal tablets No vegi dishes and no choice of meals for allergic passengers Very little space for legs"

Pros: "Nothing"
Cons: "Doctor recommended not to travel but no credit given."

Pros: "Great in flight experience! Cabin crew were very friendly and kind. Entertainment was awesome!"
Cons: "Food was delicious compared to most American airlines. However, portions were smaller. Seating is more narrow compared to standard non low-cost laung-haul airlines. You will not have a pleasant flight if you're a tall and/or a big person."

Pros: "Ok"
Cons: "Ok"

Pros: "Extremely punctual Friendly staff Comfortable seat design Outstanding entertainment options"

Cons: "No complimentary drinks, not even a glass of water. Check in was horrendous. I pre purchased luggage Check in but when I arrived in airport the automated system doesn't like to that piece of data. Didn't know that so was in a long line to use automated check in when I was supposed to be in an even longer line to have service personnel check me in. So finally after standing in both lines I did get checked in......."

Pros: "Cheap fare"
Cons: "Disorganized boarding and didn't even offer water for free on flight."

Pros: "They solve the flight connection issue and move us to a direct flight."
