Airline reviews

Pros: "Crew was OK"
Cons: "Seat was uncomfortable. There was no power outlet."

Pros: "American Airlines ancient crew could not be bothered"
Cons: "The crew could have given a care and tried to make eye contact"

Cons: "The American Airlines staff seemed like they were in a bad mood, not very friendly. Nothing outrageous though."

Pros: "Everything"
Cons: "Yes"

Pros: "The crew was great. The plane was clean. Both flights were on time and went very well."
Cons: "The one thing I must say could be better is limiting people to one carry on bag. There were a few people that held up the boarding process because they had more than one bag and they were trying to find a open slot in the overhead compartment."

Pros: "Flight going to Cabo was delayed and coming back to California was delayed. Ridiculous!!!!"
Cons: "Be on time"

Pros: "After couple or three hours the seat get to be a pain on the tailbone. Also I am 6'2" so already a bit of squeeze. Can't stretch out legs. Was an Airbus 319"
Cons: "Not much other than more room and more cushion in seats. Quick boarding in group 4, friendly crew, the Taco salad was actually pretty good. Watched 2 movies, both still premium on the pay channels."

Cons: "Nothing"

Pros: "On time despite ground hold"
Cons: "Having flight attendants board with 4 bags and taking most storage"

Cons: "A delay in take off"

Pros: "Great Airport and easy access to the gates and transportation."

Pros: "food, drinks, seats, price"

Cons: "Terrible service from crew. Bad odors from bathrooms."

Pros: "We got there."
Cons: "We found the chart listing gate where we should go. We went there. Told the last listed flight was late so stayed there. With no announcement the gate board listed a different flight. We asked and was told gate was changed. What a surprise, Went to the info board and had to RUN to our new gate. Barely made it on time. This is awful communication."

Pros: "I appreciated that they were interested in the general welfare of the whole craft in the midst of storms."
Cons: "The long delays, the cancellation near midnight, the long lines to what I thought was going to be some type of reimbursement for all the inconvenience at now having to find lodging for the evening, spend an entire day back at the airport, and transport myself from the NEW airport they made available for me from the original airport I had chosen. Absolutely NO compensation or reimbursement due to "weather." While I understand they can't control the weather, this is literally one of the greatest elements in their company. They should have provisions FOR it. Running out of airlines I could trust and rely on, and thought American would deliver. But No, not even this one. Extremely disappointed and staying away from AA."

Cons: "My flight got cancelled with zero notice and I almost ended up on a 18 hour layover which would have resulted me in missing work. The staff was very unsympathetic and not helpful. There were 10 people behind the counter and nobody could help us. They were all just spacing out. Ultimately, I was placed on the flight, but had to rush to every single one of my four connecting flights. I am a frequent traveler but this is by far the worst experience I’ve ever had. Avianca should be embarrassed to be associated with star alliances."

Pros: "Friendly curbside skycap at check in"
Cons: "I didn't realize that I was sold a "basic" ticket. No early seat assignment, last boarding group, no access to overhead stowage (didn't need it) so all bags have to be checked for extra fees, bought preferred seating just to be sure my wife and I could sit together but did not get a receipt and had trouble explaining this at curbside check in. Overall unsatisfactory. Same seats but no amenities."

Cons: "My husband started coughing really badly. I rang the call button to see if a flight attendant would come and maybe help me. Eventually, after about 6 minutes, he managed to control his breathing and still no flight attendant to be seen. Only after 20 minutes while distributing the meals, one of the attendants shuts the call sign of and continues. This is not the service we usually get from Avianca!"

Pros: "All"
Cons: "Nothing"

Cons: "The crew met their requirements. I dont think you’ll survive they dont go beyond."

Cons: "Flight network sent an incorrect name to the airline and i had to go under so much trouble the day before just to correct itz"

Pros: "Everything but the boarding."
Cons: "The boarding seemed to take forever. The crew could’ve performed the boarding process while getting the people who were waiting for upgrades at the same time. Splitting work could’ve worked and to not let all of us wait."

Pros: "Flight was on time"
Cons: "The plane was too old. It is shameful. Avianca should stop using this plane"

Pros: "Seats were comfortable"
Cons: "We landed at a different airport than we were supposed to and no announcement was made. We weren’t updated at all! When we finally landed in bogota we missed our connections and couldn’t get on another flight for 14 hours"

Cons: "Just never enough leg room❗️"

Pros: "Plane and staff were great. Very easy boarding process and we landed early in Dublin airport after an hour delayed take off. Food and staff service was very good, no complaints."
Cons: "No idea how they messed up the take off and landing times so greatly. left an hour late and arrived an hour early. No personal entertainment screen and plugs were not working."

Pros: "Very little legroom for a 5 hour flight."

Pros: "Smooth flight and on time."
Cons: "Small plane. Even small carry-ons had to be gate checked"

Pros: "Nice staff"
Cons: "Luggage is lost"

Pros: "Only 30 minutes or so to ORD from GRB Paid with AA points at 7,500 miles each way for a weekend in Chicago"

Cons: "Los asiento demasiados pegado. Y el snack muy pobre"

Pros: "Great service and Manchester is way better than flying to Boston"
Cons: "Your rating app doesn't have a N/A option"

Pros: "In seat entertainment screen and USB charger. The chicken salad"
Cons: "Flight crew were rude, wasn't sitting next to my partner on the same booking for both flights. Had to pay for wine, they couldn't even give just one complimentary wine with dinner. Dinner was bad except the small chicken salad was good"

Cons: "Carry on luggage does not fit for the whole plane. We had to check and wait for it to be unloaded in the jetway."

Pros: "Great service. With FOOD!!! Real Food! The entertainment system was great ( I played most of the flight) On time!"

Pros: "Food was goof"
Cons: "Staff never smiled or even said hello. May be culture but better training is needed."

Pros: "Service/crew."
Cons: "Entertainment is rather limited."

Pros: "It was quick and we had a smooth landing...."
Cons: "Upon arriving in Lima, Avianca 808 passengers became aware that none (zero, nada) of the bags were loaded onto the plane in Cusco. The customer service response to this airline error was sub-par. Passengers were told that the baggage issue was "weather-related", which is ludicrous even if the weather both in origin and destination had not been clear and sunny with no wind (it was). Info was taken on if passengers needed bags sent on to another destination or to a hotel but were told it would not get to Lima until the next morning (this was flight 808 landing just before 4 pm). Unclear why it couldn't be put on the next flight same day. And unclear what is happening to our bags now until the morning. No apology wasn't issued to passengers. Additionally we were delayed 15 mins due to "weather". I don't mind short delays but it was absolutely not weather-related. Weather is the default excuse to transfer fault away from themselves."

Pros: "More spacious seating."
Cons: "All ofd the overhead bin carry on luggage left no room atg all by the time we boarded So hence the leg room was very crowded. When will the airlines stop the ridiculous over use and abuse of carry on unchecked bags?"

Pros: "They got us seats on a Latam flight later in the day."
Cons: "I don't like being bumped from a flight when you have e-tix in hand from a month previous purchase for three travelers."

Pros: "La puntualidad de los vuelos."
Cons: "El vuelo lo operaba American Airlines y no parecía una línea con alianza de vuelo ..chek-in automatizado no apareció mi boarding así que hacer fila para resolver..afortunadamente lo hicieron de una."

Cons: "No entertainment"

Pros: "Great food and headphones"

Pros: "Entrtainment and food."
Cons: "Crew service and attention very poor. Terrible experience with flight reconnection for me and my group of 5 people. Had to wait 5 hours for the crew to confirm ticketing, w.e were lied to and watched how others got preference before us. Crew gave us inconsistent explanations and had no knowledge of how to solve the problem."

Cons: "I boarded in group 2. A lot of the overhead space was already full due to the large number of priority passengers. This led to people having to go to the back to find space for bags. That creates a lot of jams at the end of the flight. Also, younger passengers often try to rush out of the plane rather than waiting for their row. This should be stopped."

Pros: "the flight was on time"
Cons: "the plane was small the plane was not comfortable"

Cons: "Company blamed weather for flight cancelation and did not pay hotel and meals. Onboarding crew were very rude and not helpful, Food provided in the flight is very bad."

Cons: "The flight was delayed and we spent about an hour just sitting in the plane before we took off. When I expressed concerns aboit making my connecting flight to the front desk representative she stated she didn't have time to help me as she had a plane to board. It was another 20 minutes before she even began to board anyone. She was very abrupt and rude. I had to call AA while sitting on the tarmac to get rebooked which was a more positive experience."

Pros: "Boarding was good"
Cons: "No drinks or snacks. We were told the hour and a half flight was too short for service. Really??? First class got their drinks."

Pros: "On time"
Cons: "Upgrade seating"

Cons: "We had to wait for about seven hours at the airport because the flight was delayed."

Cons: "The flight was delayed for almost five hours."

Cons: "Food purchase options and better snacks"

Pros: "Nothing"

Pros: "No problems"
Cons: "No issues"

Cons: "Despite dozens of empty seats in Economy Plus, flight attendants refused to allow anyone to move into the 8 vacant rows keeping us crowded in coach economy."

Pros: "We landed 45 minutes early!"

Pros: "No"

Pros: "Liked the exit row."
Cons: "Hated the delay of more than 90 minutes."

Cons: "My seatmates and I were frozen for the whole flight, especially our feet - even with socks on."

Cons: "A very old B757. late departure. No explanation."

Pros: "Nothing..."
Cons: "50 characters isn’t enough to describe the pain I went through. United airlines screwed me. Canceled flight and didn’t compensate me only with a flight to Chicago and a 15 hour wait for the next flight... no hotel or food... no transportation."

Pros: "Más espacio, al menos una película que ver, y algún bocadillo por ser un vuelo de tantas horas"

Pros: "Left on time, friendly crew, comfy flight."
Cons: "For reasons I still don’t understand my baggage didn’t travel with me and I was not able to get it until several days later"

Pros: "Seats were quite comfortable. Service pretty great."
Cons: "The only issue was checking my bag at MHT. The guy at the desk had no idea what he was doing, and it made me really nervous."

Pros: "Ended up requesting a refund. Received zero compensation and zero empathy from anyone at United. Left the airport infuriated and drove to my destination instead."
Cons: "Ended up requesting a refund. Received zero compensation and zero empathy from anyone at United. Left the airport infuriated and drove to my destination instead."

Cons: "My flight was canceled because of the hurricane in Houston which was completely understandable. Trying to rebook a flight was one of the worst experiences I've had on the phone. Over 2 hours on hold only for United to tell me to call back inside 24 hours of my requested departure (which was about 12 hours outside of the time I called). Bad customer service all around, both Kayak and United."

Pros: "It was the worst trip I have ever taken. Delayed 2 hours due to air traffic control problems, then they landed us in Baltimore and decided we were gonna take buses to Newark. They put us back on the plane and drove around the runway for 2 more hours until I finally had a panic attack. I got off. Then they pulled everyone off and 3 busses took us to NJ, arrival at 4 a.m....HORRIBLE crew had timed out, horrible stewards served up water in cups and were yelling at people to sit saying we were NOT getting off the plane."
Cons: "UNITED AIR"

Pros: "The flight attendants very sincere & nice. I love that their was a lot of leg room on the flight as well."

Pros: "Nothing"
Cons: "Everything"

Pros: "Niven cabin crew, helped without complaint when my daughter had an embarrassing accident. Very nice crew."
Cons: "No in seat free entertainment"

Cons: "There was no entertainment alternatives."

Pros: "Love the cookie! Good crew."

Pros: "Service was good"
Cons: "Delay 8 hours with short notice I had 2 take Uber 90$ 2 Boston airport"

Pros: "Quick flight."

Cons: "AC was extremely cold"

Pros: "Nothing. Never again"
Cons: "Rude and unhelpful. No empathy or concern. Erik"

Cons: "They kept delaying the flight. Finally, I decided to drive 6:30 hours."

Cons: "Flight was cancelled and initial Customer Service Representative was not helpful at all."

Pros: "Any"

Cons: "Flight was delayed 2 hours from Manchester, which would have made me miss my connecting flight to MIA"

Pros: "Trip and treatment were ok... but tv is way expensive. Avianca offers you a wide range of movies and tv series for free."

Pros: "Nothing"
Cons: "I don't think it's fair that you don't any money back of you cancel your plane ticket. It shouldn't matter what type of ticket it was. You should at least be allowed a voucher for the amount of the ticket at a later date. Even if it's a percentage off, you should be allowed something. How is it that you can buy a car worth thousands, and be allowed to return it under the Lemon Law. When a company called can make billions of dollars doing this, it's just taking advantage of the little people."

Pros: "It was a small prop plane but the flight was amazingly smooth."

Cons: "our flight was delayed more than 2 hours due to weather. Of course, not a pleasure to have, after flying so far, but I appreciated how apologetic the crew and pilot was, under the circumstances"

Pros: "not to mention non existent entertainment. TV never worked no.map. no interesting info from pilot unlike last pilot we'd had on this flight who'd given us great information on our flight. no apologies. we were told about 50 tvs were out on the flight. the chicken meal was delicious pasta awful (we shared because of that). the couscous salad which lady flight had been super this time was too spicy for us much less if we'd bought a child. if this is the positive ... we got there safely and the boarding was better than sometimes."
Cons: "see above. united which ran this flight more intent on telling you what you can't do than making it a pleasant flight. no entertainment. 75 per cent of food was inedible. will be looking at Ba in future or Virgin despite being United mileage plus members. how about some customer service training?! as a repressed brit living in us I'm not normally a picky passenger. but a smile? sorry the movies aren't working? hi? just the greeting over the intercom makes you feel as if you are an inconvenience. not friendly skies thus time. put off."

Pros: "Easiest boarding process I've ever had. Terrific!"
Cons: "No in flight entertainment, small cramped"

Pros: "They gave us free entertainment"
Cons: "We took two hours in taking off"

Pros: "It was timely, and the flight attendant was wonderful!"

Cons: "Both flights were delayed by 20 mins which made it hard for the connecting flights"

Pros: "The seating was surprisingly comfortable. There was plenty of leg room."
Cons: "Nowhere to store one's belongings in the seat I was assigned. It was difficult to get anything needed during the flight that was stored in the overhead (3 seats back)."

Pros: "Flights were on time, and arrived early at each destination"

Pros: "Male flight attendant was friendly and relatable"
Cons: "Very rocky flight, female flight attendant was mocking male attendant, reading from the manual so I was hearing all the possible worst things that could happen and sanitary conditions of the bathrooms, very unpleasant. We also ran out of water so instead everyone had to wash their hands with the bottled water and sanitary wipes"

Pros: "I like very much, nice and smooth, I'll recommend this company, food was good attendant excellent and friendly crew. Thank you it was a pleasure travel with United Airlines"

Pros: "Vegetarian food was available and that was the only likeable part for me. Every else was strictly ok."
Cons: "Nothing exceptional. The flight crew definitely needs to to tone down on their attitude and customer service skills. Short distance traveling is fine but definitely not recommended for long distance."

Cons: "Upon arrival at Manchester airport a conversation was overheard about my flight being delayed 8 hrs. When I approached an employee she was abrupt and rude. The second employee when I inquired simply stated you will have to rebook gathered her things and left. Went to the desk rebooked the flight she asked if I had my boarding passes which I didn't because she hadn't printed them she then got them for me. I finally board the plane to get to Chicago and needless to say again the crew was held up and put me into another delay. I gave United another chance to do things well as I have had similar experiences in the past they failed. I would rather spend more money than deal with such frustration."

Cons: "Actually I never got a flight to Seattle yesterday. My flight was cancelled and was on hold with United for over 2 hours only to have them tell me they could rebook for two days later. They said that was the only option in the whole Midwest on all airlines. I don't believe them. Horrible customer service. Ive had nothing good to say about United. I am supposed to fly through Newark tomorrow to Seattle and I hope that flight isn't cancelled because I've already missed two days of work. I am very displeased right now. No compensation either."

Pros: "The first on-time flight I've experienced from United. I also was able to check my bags for free."
Cons: "The passenger next to me was showing unwanted photography of his erect genitals during flight. I was so uncomfortable that I spent most of the flight in the lavatory. I flagged down United stewardesses but they were unwilling to hear about how I was visually assualted. United does not care about the comfort or safety of their young female customers."

Pros: "Great service by the crew"
