Airline reviews
Pros: "Nothing"
Cons: "Entertainment didn’t work, the crew did nothing to help. The plane was hot and stuffy. My luggage is lost."
Pros: "Nothing"
Cons: "Entertainment didn’t work, the crew did nothing to help. The plane was hot and stuffy. My luggage is lost."
Pros: "The crew service was very good, as was the food. The only complain is about the entertainment, hope to update the touch screen."
Pros: "Excellent service from the crew and prices were good."
Cons: "The seats seem to have gotten smaller and were rather uncomfortable for a 7 hour flight."
Pros: "On time arrival"
Cons: "Boston -Zurich, the most uncomfortable seat possible. I am 5’2 and I barely fit.... Seats are way more comfortable on European flights."
Cons: "The temperature on this overnight flight was sweltering Legroom was poor"
Cons: "The plane was ancient. offer wifi- at least be able to pay for it. charger outlets."
Pros: "After having read Swiss Airline reviews I was prepared for a difficult and uncomfortable trip from BOS to ZUR. I was pleasantly surprised to the kindness and comfort I found in the economy class of Swiss Airline. Bags were checked in, flight was timely and legroom was satisfactory. I would highly recommended Swiss Airline due to my overall experience."
Pros: "The staff upgraded me to business. It was a great wxperience"
Pros: "There were good entertainment options though I didn’t use them"
Cons: "Our flight was delayed 2.5 hours, during which we had boarded but were told we could not leave our seats even for the bathroom. We were offered a cup of water once during this delay which is inexcusable. (We were also woken up to serve dinner at 1am so that was incredibly inconvenient for an overnight flight) On top of that, I, as well as many others missed our connecting flight. Personally I missed my connection by 20 minutes, which seems a reasonable amount of time to hold a connecting flight with so many people from our flight on that next one. In missing by only 20 minutes, we have lost an entire day of our trip and are spending 9! hours in the airport today. There was no communication between flights clearly. Despite there being an earlier flight we could’ve been placed on after missing our connection - we did not get booked on this flight. I asked why and they just randomly placed people on random flights with no regard for when we showed at the desk. In this scenario, a first come first serve would have alleviated an absolutely awful experience. I will never fly Swiss Air again and will urge people I know to not fly this airline. The experience was extremely frustrating, the best response from an employee was “that’s all I can do for you” and I wish it on no one."
Pros: "Took care of every need with a smile and class"
Cons: "Seats uncomfortable"
Pros: "Very smooth boarding on both flights, a smooth transfer between flights, and comfortable seats (especially nice flexible headrest on longhaul flight). Very friendly and helpful crew."
Cons: "Movies available weren't to my taste, which isn't important anyway."
Pros: "Seat was very comfortable and lots of leg room. Food was good."
Cons: "very rude and extremely racist group. I will not fly them again."
Cons: "Nothing. The plane was clean, everything was on time, and everyone was polite and professional."
Cons: "The food was so cheap... pasta and a muffin. I’ll be looking around for another airline."
Cons: "Boarding process was not easy to hear and it was unclear where the line for our gate ended and the line for the gate right next to ours began"
Pros: "Very good drink service (one cold and one hot drink)"
Pros: "Absolutely fantastic service from the check in counter until deplaning. Delicious food, snacks & even wine & other alcohol included. The staff is super friendly & very tentative. It was really a treat to fly Austrian Airlines."
Cons: "This is just nit picking and if I absolutely had to I’d just hope for a more of a variety of movies, TV shows & music if possible."
Cons: "I didn't like that I paid for a ticket months ago and checked in my bags and then was told that there's no room the plain is full"
Pros: "Great food. Exceptional service. Clean airplane and toilets. The whole flight was smooth and comfortable. And we were in coach!!!"
Cons: "All was great."
Pros: "Baggage policy and amenities on board as well as the Istanbul airport as a connector."
Pros: "flights on time. special meals I ordered were provided."
Cons: "very long check-in line. took over 1hr to check in. tried to check-in online in advance, but system did not allow me to do this."
Pros: "Slept in the flight for 5 hours and my toddler did too , was quiet in the cabin and this is the only good thing"
Cons: "Boarding they kept me and couple othee guys like seeiously 5 staff people at the gate doing nothing and you ask anyone please help i want to tag my stroller so i can board ans go on boarding line, no response only one peeson will work. the rest of the four are completely useless, i eventually told my wife to board with our daughter so they have the time to sit and prepare food etc and pull things they will need durimg flight Andi waited on this last staff person at the gate until she gave me the tag to the stroller and boarded later First meal they said either fish or beaf meat balls, i like both and no problem, but the crew said no fish anymore so you you will take beaf, OK Luckily neither my wife or daughter ate it Because after I ate it, 3-4 hrs later, I had the worst stomach pain ever and was in pain the rest of the flight and the remaining of the day after we landed FYI I ate just crackers and like all bread sandwiches all morning and was completely fine- just the beaf meat balls either not cocked or remains of non good beaf and other things- horrible food"
Pros: "good people /service, good food and comfortable seating nice experience all in all"
Pros: "Turkish Airlines offers an experience much better than your average two-hour plane hop in the U.S. There was a full meal served, staff were kind and didn’t try to sell a bunch of extra stuff to you, and there were many choices for in-flight entertainment."
Cons: "Unfortunately, the children on the plane were really poorly behaved and loud. In addition, the flight was delayed by 1 full hour and when we arrived in Vienna our luggage (and the luggage of many other passengers) had not been sent with us. We waited in line for luggage for 30 minutes, then another line for at least 30 more minutes to report the missing bag, and we were then told that it wouldn’t arrive for another day and would be delivered to us within a 3 hour window in the middle of the day. This was essentially an entire night and day lost to a mishap that the airline didn’t even notify us of when we landed. Pretty frustrating."
Pros: "Great entertainment, good seat comfort (even in economy seat), good food and friendly service."
Pros: "The crew was very attentive. I was surprised at the amount of food and drink service. It was nice to have on such a long flight. Seats were comfortable and I was able to sleep well which is not easy for me on planes."
Pros: "The crew are very friendly and in general and the flight was very nice"
Cons: "Need to have a bigger seats"
Pros: "All was great, until..."
Cons: "... the person in front of me reclined their seat. That was the end of my comfort. I’m 5.11”- 1.80cm. Couldn’t watch tv, had trouble eating."
Pros: "The flight was slightly comfortable, there were more food and snacks options than in other aircraft companies."
Cons: "Some of the crew were very rude, making a point to show you that they were hassled by serving you. I thought that was poor service. The seats weren't all working so while the passenger in front of me reclined, my seat wouldn't making for a very uncomfortable flight. I thought the entire aircraft needed either renovation or retirement altogether. Old TVs and non-functioning seats, all made me kind scared of where I was tbh."
Cons: "All of our luggage was lost and did not arrive in Prague"
Cons: "Tv screen didn’t work very well. ( picture was fine but the function buttons were terrible)."
Pros: "The downstairs bathrooms were great: five roomy clean bathrooms, always one available. The crew was superb, professional, kind, capable. The entire trip was perfection. The timing of both flights, the airports, it was travel at its best. We love Lufthansa. We have tremendous confidence in them."
Cons: "The food was just okay. A better choice of wine and greater selection of spirits would be nice."
Pros: "Middle seats had little useful legroom due to conduit"
Cons: "The plane was hot, muggy, and had little airflow with no user movable nozzles. Lots of people sweating for 6+hours."
Cons: "Light was delayed 3 hours. I had to wait 9 hours for a next plane to my final destination"
Pros: "the seating supports under the seats are truly ridiculous. impossible to store bags"
Cons: "seating"
Pros: "Smooth quiet flight."
Cons: "Mac and cheese isn’t what I was expecting for vegetarian."
Pros: "I have never been treated so poorly by counter people in my life!"
Cons: "After 2 hour delay, the flight was cancelled. NO ONE helped to find another flight. After waiting in line for 2 hours, the ticket agent handed me a card and said I had to call the 800 number. The person on the phone said I had to talk to ticket agent to go standby on a flight to Munich and the ticket agent told me I had to call. I was caught in a loop and no one helped. Then when it became apparent I wasn't getting out that night I was informed that there were no hotel vouchers and I would have to find my own hotel! After searching for an hour for a hotel (all were sold out in Boston) I called a friend who lives outside of Boston. No one gave me a taxi voucher because it was not to a hotel. LUFTHANSA customer service is the WORST!!!!!!!!"
Pros: "Cuteous service"
Cons: "Seats were to close together, nomlegroom, impossible when set in front reclined. Breakfast food meager."
Cons: "Passport control in Frankfurt was slow, very long linen under staffed"
Cons: "I booked a business class, round trip ticket, only to find out that one of the legs was not."
Cons: "Cabin crew makes way too much noise on an overnight flight. On these flights, the focus should be on letting passengers rest, and limiting announcements, even if that seems to take away from the perceived level of service."
Pros: "The crew was efficient and well trained"
Cons: "The food needed salt and the bread was a little dry."
Cons: "The seats could have been more comfortable and . The plane was over booked"
Pros: "Both ground crew and flight crew were courteous and friendly."
Cons: "The meal was between edible and mediocre. It would have been nice if the hot beverages were served with the mini breakfast before landing."
Pros: "Decent legroom, pillows and blankets, food and drink all at no cost (paid for bag, opted not to pay for seats and still ended up together)."
Cons: "The flight is advertise as a British airways flight which flies out of teminal E in Boston. In reality the flight is through aer lingus which flies through terminal C. This should be clarified upon booking...."
Cons: "Supposed to leave Boston at 9:30 pm, instead 1:30 am. It was said they knew this the day before and sent emails to passengers. No one who I spoke to, including myself, got one. Aer Lingus hired another carrier to do this flight—plane, crew —no Aer Lingus personnel. Everyone was nice, but. Had made arrangement for early morning checkin. Got to the hotel SO late that they waved a fee and had our room ready. Was going to sightsee the first afternoon—basically lost a day of seeing Dublin."
Pros: "Timely departure."
Cons: "Staff did not seem engaged in customer service, did not go up and down the aisles to collect cups, paper, etc. very disappointing in tight space."
Pros: "We arrived safely."
Cons: "They announced that it was different aircraft, different airline operating the flight. It was an hour late. Then they lost our luggage."
