Cons: "I was randomly selected for a second security check at the boarding gate in Zurich airport, the security staff were unfriendly, said it was a TSA requirement even though I stated I am a United States Citizen and That I have already passed through a complete security check Point, still they placed a metal & scanning detector on my feet, hands & belt. This was a complete violation of my rights. Never have I faced a humiliating situation at any other airport.

We entered the plane last.Our seats not were ready and we were forced to do it all alone.Rudeness and unprofessionalism of SWISS crew.The end of the vacation was spoiled. For what I paid to SWISS 100$ in advance(10 monthes)? I believe, if SWISS could not provide the paid service as expected, SWISS must return the money(100$) and apologize. Nobody apologized in Zurich, threatened to invite the police. Bad crew, bad service."

I am flying with swiss every month between Zürich and New York but a lot of Ines I get a shitty seat even if I am silver status As a frequent flyer I expect a priority handling which is not the case . No upgrade poaaibility due to wrong booking class (even if flights are very expensive) if this continues to go that way I will change airline alliance This is more a miles and more issue but it is really annoying me in a way that I really consider changin"

Cons: "Seat was terrible g43 have no room for your leg. Seats are to small. Huge man next to me was sitting on 1.5 seat...."

So then we needed to get in ANOTHER line and get the stamp and then stand in line AGAIN just to get on the plane! For being Swiss you'd think you'd have this part down AT LEAST! Boarding by seat number would have been a better idea. Everybody was all over the place getting their bags stored above."

Pros: "Food was good and so was the movie selection"
Cons: "Boarding was slow and the interviewers were disrespectful. Also I was upgraded last minute and I could never understand the system by which upgrades to first class are granted.

Pros: "Going by and come Ming back Atlanta check in desk was the rudest Laziest most disrespectful emoyees I have ever came across .

Going from Atlanta to Fort Lauderdale the check in person was so rude there where 5 people askI’m her what’s her problem . The crew the flight was excellent but the Atlanta check in desk really dropped the ball 2 times . If I was the manger I would fire the whole staff and If I was above the manager I would fire them as well as I’m. Sure this is not an isolated occasion."

Pros: "Very friendly crew"
Cons: "Lack of subtitles on available movies & series"

Pros: "As poltronas estavam OK."
Cons: "No voo MEX-GRU o Sistema de Entretenimento nao funcionou por quase 3hs. A refeicao foi muito fraca, tamto no jantar quanto no café da manhã. Onde ja se viu comer feijão preto com onelete no cafe da manhã??? Deveriam pensar no tipo de passageiro q estao atendendo."

Pros: "Seat was comfortable, food was good."
Cons: "The woman seated next to me was the mother of one of the flight attendants. She had terrible body odor that nearly brought me to vomiting—and this was a 10 hour flight. She was also brought all kinds of amenities from the attendants from the 1st class cabin—not really appropriate."

No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags.

One child had one on tye chair and I asked him if its suppose to be on the seat or given later on. He said it will be passed later and then with a patronizing manner he gave another head phone set and said: "I guess we havw an emergency". On the flight, every time he with the food and drinks he just stood there next to me talking over my head with the passenger begind me. Very uncomfortable, especially when it happens 6 or 7 times. When asking what drink we wanted ( the first time), i replied apple and orange juicewith no ice. He replied, with a patronizing manner "this it European company, not American company. Here we don't put ive if you do not ask for it".The incident that bother me the most is one that involved my kids also. My daughter (3 years old) was a bit scared of the flight, tired and did not want to sit on her chair. We tried to keek her on the chair buy she started crying laying down on the floor infront of our seats. Jorge the flight attendant saw her and told me to put her on the seat. Not in a manner I expect out of soneone in the service industry. I told him we are working on it and we will have her on the chair as soon as we can. When I said that he got irritated and a bit aggressive. For no reason the situation became hostile. The flight attendent on the other side (do not know his name). Can over and asked us what we needed amd if we need help. I told the other flight attendant we need 5 minutes and he said OK. After a few minutes she calmed down. Anotger passenger asked Jorge what beer it is and he replied, with contempt, " its German beer, its good"."

Pros: "Pleasant crew."
Cons: "Annoying kids in seats behind us :( Not enough leg room for someone over 6 feet tall."

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."

Pros: "Food and hospitality and staff"
Cons: "We were late 20 minutes and sat in tarmac another 15 minutes. Didn´t allow us enough time to get train, take bus, we had over 500 people lined up for bus, get through TSA, they pulled my suitcase for inspection, but didn´t look at it for 15 minutes until i called a supervisor as my connecting flight was leaving, and in fact, it had left as TSA does this purposefully and maliciously as it apparently happens all the time per ÇBritish Airways who had to reticket us. We had to return to A section another 20 minutes to be reticketed and luckily got on another flight to

I was wearing an orthopedic shoe, due to a toe fracture and i had to walk again all this long distance back to the terminal.!! British airway gave another flight and had to pay $279 dlls for a ticket to Madrid.2 hrs later. My flight was by Iberia and the service. was excelent. I wonder if the insurance , I bought initially will cover something of the $ 279 dlls ticket ? Fligth back to EUA was by AA and service was excellent"

Cons: "The seats on these flights are poor. As well as being narrow, there are bars on either side that dig in to your sides. My ongoing one hour domestic flight had more comfortable seats. Fod choice poor. Chicken Curry or Cheese/Tomato Lasagna. If I want a vegetarian meal I'll order one beforehand. Give me two meat options. This isn't the first time I've noticed this. Is it cost cutting? Seems like it to me. Not impressed."

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

Pros: "Very little."
Cons: "Flight was delayed. The seats are uncomfortable and too small for even normal size male. Food was disgusting. Staff were very nice and helpful if asked. I think all the space and comfort were in buisiness and first class. Economy class is still paying for a ticket, make up most of the passengers and deserves better. Getting into a seat was like getting into a straight jacket."

Pros: "The food was better than expected and the crew did everything they could to keep us comfortable"
Cons: "That plane was so gross. The upholstery was stained and frayed. It was also insanely small. Holy cow!"

Cons: "food was not good."

Pros: "Absolutely nothing"
Cons: "Flight was delayed by 2 hours. Then they bumped us out of the seats we had reserved. Made it just in time for our connection. Then they bumped us from that flight. Others were given generous compensation for that bump. However we were given nothing. At least they us we could rest in the BA lounge because I am elderly and disabled and we would have a 9 hour wait. Got to the lounge and we were not listed in the system. So we were denied entrance. We will have have spent 2 nights on a plane and 36 hours instead of one night and 16 hours. Rotten way to depend your 50th anniversary."

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

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

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."

Pros: "Clean, not crowded, and the crew was friendly."
Cons: "In economy class food was only available for purchase, although it was dinner time. Boarding was a little late."

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"

Pros: "The food was elevated and we were fed twice on our 9 hour flight! The beverage service was also provided often with a good assortment. I loved that there were new release movies available for free. The staff was friendly and available. If I were to do another long flight like that, I would seek out British Airways."
Cons: "Nothing."

Pros: "Wine with dinner."
Cons: "No tv for 9hr flight. Breakfast was awful."

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"

Pros: "No turbulence!!!"

Pros: "Overall an excellent trip. Easy boarding/exit."
Cons: "Did not purchase food or entertainment."

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

Pros: "I used frequent flyer miles for the tickets."
Cons: "The crew was late getting to the gate. All of them talked to me like I was a child they were disappointed in. No one smiled. I thought all of the crew was mad at us for using their airline."

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

Pros: "Crew was nice"
Cons: "Lots of empty seats... during covid/social distancing there should only be 2 ppl in a row especially if there is room...it was crowded and not consistent with signs posted saying stay 6 ft apart"

Pros: "Nothing."
Cons: "Everything"

Pros: "Good, cheap flight that gets the job done. No issues boarding, seats were fine. Cannot comment on most things as I fell asleep almost immediately."
Cons: "Would've been nice to have had an eye mask / blankets on a red eye flight..."

Cons: "They have very long and annoying credit card announcements"

Cons: "Delay due to equipment failure, were not able to estimate delay"

Pros: "American"

Cons: "Two hour delay out of Denver, no crew."

Pros: "Nothing."

Cons: "The crew was a little late"

Pros: "Not using kayak"
Cons: "Kayak booked me the worst itinerary in the history of air travel!"

Cons: "Seats are cramped"

Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "Nothing"
Cons: "Broken plane, re-route and conflicting inaccurate email updates."

Pros: "Nothing!"
Cons: "Almost everything!"

Pros: "Pilot made up time so we made it in early!"

Pros: "The helpful steward"
Cons: "The bumpy ride"

Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."

Pros: "On time. Efficient boarding."
Cons: "Stingy with the cookies. Somewhat uncomfortable seating. But what can anyone expect anymore?"

Pros: "Service was one of the best I have received for an airline."

Pros: "Friendly service"

Pros: "Food and entertainment were great"

Pros: "Everything was on time and handled efficiently and courteously. I was pleased with everything."

Cons: "Too cold, even with air off above me."

Pros: "All good, except poor prep on food"
Cons: "As above"

Pros: "Good connection"

Cons: "Maintenance problems, late departures, uncomfortable airlines"

Pros: "Everything"
Cons: "Nothing"

Pros: "nice flight - nonstop got us exactly where we want"
Cons: "not a big selection on food... just cookies (although good it would be nice to have some selection)"

Cons: "The flight was delayed 9 hours for mechanical issues and they were not able to do anything. Since booking with Kayak neither Alaska airlines or American Airlines would help in getting us an earlier flight and both airlines said they couldn't help after repeated calls. Won't be booking any American Airlines flights throug Kayak again."

Pros: "Everything ran smoothly despite turbulence and bad weather, thanks to the crew."
Cons: "Seating is even more cramped than I'm used to, and everything outside of a drink and a biscuit is extra money."

Pros: "Nothing"
Cons: "Everything"

Cons: "Delayed flight due to crew."

Pros: "Easy flight, friendly crew."
Cons: "Girl next to me being sick the whole time"

Pros: "Getting through security was a lot better than I thought. Also, I had plenty of room and the overall ride was smooth."
Cons: "I just wish that there was a little more room and easier ways to earn miles and entry into the lounge."

Pros: "Wi fi did not work."

Cons: "Sitting on the runway after landing because the gate is occupied."

Pros: "No surveys"
Cons: "No surveys"

Pros: "El problema es que el vuelo estaba sobrevendido y han cerrado las puertas antes con lo cual me he quedado abajo sin pode abordar. 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"

Pros: "The Denver airport is beautiful"
Cons: "I will never fly AA again - see below"

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

Pros: "Overall great flight and great service. No complaints!"

Pros: "I liked everything from the way they got everyone on the plane to getting everyone deplaned."
Cons: "I didn't have a problem with the airline. Just a couple of passengers."

Pros: "My departing flight crew was very accommodating for my baby and I. They were very pleasant."
Cons: "I wasn't able to board first with my baby, so I had to try and walk through all the passengers with a baby, diaper bag and small carry on. It was a little difficult."

Pros: "On time. Good crew and nicer flight."
Cons: "Actually no complaints."

Pros: "Entertainment modules in cabin were nice"
Cons: "Forced to check my bag in at the gate. Upon completion of boarding, there were several empty spaces in the overhead bins, and my bag could have fit easily. Upon arriving in Houston, baggage claim was VERY slow. Small flight of less than 30 people. Southwest had 3 flights arrive and complete baggage claims by the time our bags became available. Airport personnel confirmed that it is typical or normal for American because they operate with a small "skeleton" ground crew. Flight arrived just after 11:20pm,, but wasn't able to head out for transportation until after 12:30am. VERY upset and disappointed with service."

Pros: "Friendly service"
Cons: "Snacks"

Cons: "American delayed the flight 7 times before cancelling it. They then put me on a flight 7 hours after the initial departure time. That flight was delayed 7 times and then they cancelled it. I wasted 10 hours at the airport."
