3hr delay and then missed connecting flight with another 6hr wait at the airport before getting a continuation to my trip, worst trip ever in my 50+years of flight travel

3hr delay and then missed connecting flight with another 6hr wait at the airport before getting a continuation to my trip, worst trip ever in my 50+years of flight travel

Without a doubt, my “customer service” experience with SWISS was the worst of my life. Multiple disconnections in conversations, very cold and indifferent staff, failure to follow up with promised status updates — simply put, T. H. E. W. O. R. S. T. A full week later, and I am STILL waiting to hear from them. Never again for me with SWISS. Disgraceful.

The flight and all amenities were good to excellent. SWISS was awful to deal with. Every step of the way they nickel and dime you. Chose your seats? $14. Change your seats… No accounting for the prior payment. You get billed again. 17 pound restriction on overhead luggage, nonsense. It’s a weight in the plane whether it’s in the overhead or in check baggage. They just milk you for every cent they can and I resent it. The flight was excellent.

plenty of legspace, snacks, no pull face from flight attendants when asking for a wine. Also fast transfer ability at ZRH.

The flight itself was fine, but due to a snow delay my connection to Lisbon was delayed by six hours. Despite this, Swiss Air still managed to lose my luggage. Not acceptable. Someone else on the flight also lost their luggage.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

The trip was great until my luggage was lost on transfer from United to Swiss. It took Swiss 3 days to get my luggage to me though it was located almost immediately.

Horrible!! The WiFi was not working, the food was awful

We’ve never been more uncomfortable on a flight than we have on this particular one. The seats in front of us reclined so far back that when the person reclined their seat of broccoli, it almost hit me in the face and left me with literally no room to move that said I had to recline my seed in which made the person behind me upset. It seemed like the seats also would recline without even pressing the button in the armrest and would unrecline as well for that same reason, and it also seemed that some seats reclined more than others. The bottom cushions of the seat were so thin that even after one hour of an 11 hour flight, our tailbones were so sore. It seemed like an overall old airplane. It also didn’t have individual air vents and it was extremely hot the entire flight. Several passengers were commenting on how hot it was. The breakfast was some kind of flavorless triangle, puffy egg, laying in a watery bed of steamed peppers and onions and spinach. It was not appetizing at all. The flight crew was extremely nice so that was a nice thing this flight attendant. They let us try different types of Swiss sodas, which was really nice and the dinner was actually delicious but still overall given the other considerations. It was pretty much a miserable flight without basic seat comfort.

Zürich-NY part of the trip was really good! Enjoyed professionalism and courtesy of the crew, comfort and cleanliness of the aircraft.

It was perfect! United Airlines staff was extremely caring, super friendly and professional

United has maintenance issues and can then never recover. No operations ability and simple issues always turn into multiple hours long cascading delays. Worst airline on earth.

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

Lost of requested seat assignments. Lost my husband's meal choice

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

No screens or meal options. Freezing cold. Dirty seats. Left late.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

Food choices limited & not enticing Seats quite uncomfortable & difficult to control

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

Late flight Delays Poor service Poor staff Worst airline ever

We exited from a plane from LAX TO MUC containing 853 passengers. Passport control was packed and very slow as they fingerprinted and photgraphed everyone. After finally getting though we ran to the gate listed on our boarding pass. We made it just as boarding was suppost to begin. No one was there. We started running again and found a Lufthansa gate open and spoke with them. We were told the gate had changed and they called the correct gate that we were coming. We started running again, but needed to wait for the train to get to the correct terminal. Running again we made it to the gate. The plane was still there but they said it was too late. So we went to the Lufthansa help desk, they told us it was our fault for missing our flight and that if we didn't buy a new ticket from them for €256 each our return trip to the states would be cancelled. Needless to say this was very disapointing to find out on the day before Christmas that we had to pay an extra €512 to complete our trip we had already paid $3344 for. We were left with no choice. No Christmas spirit there. Unhappy custumers.

I liked that we got there safely. I disliked long delays, gate and ticket agents incompetence and apathy and having my luggage lost. Five days later I've yet to get anything more than a generic apology from British Air. Luggage yet to be located, much less returned.

Canceled flight late London to Florence. Help at airport very poor. Treated poorly. Had to sleep in the airport. Lost bags- still do not have them. Horrible. I should be reimbursed!

Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

Wish the food and overall service was better. They treat Business class passengers same as economy

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

The issue was not with BA it was with the link yoiu sent fopr booking the flight

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Great crew. Food was pretty good. Seats are narrow and internet is expensive

This Condir premium economy is terrible. All it is is a few extra inches of legroom in an economy seat. British airways premium economy is the same as a first class domestic seat, wider with more recline. Plus the flights were all late to leave, arrive, etc. terrible day.

Absolutely the worst food I ever had on any flight. Half of passengers simply didn't eat their meals, as I noticed.

Food could be better. Service was just ok without any enthusiasm...

The breakfast snack was horrible. No nutrition value. I couldn't finish it. The main meal had no taste, no real vegetable, the brownie had no chocolate taste., I was not even sure what the salad consists off.

Breakfast was terrible. Sugary yogurt, inferior pastry, poor quality fruits. No protein.

Our connection in Frankfurt was the worst ever. No one from the airline or the airport seemed to be bothered to get us into our connecting flight on time! The procedures at the airport took us forever and we barely made it into our flight. If we had missed it, I’m sure we would’ve missed our cruise. Looks like everything is on autopilot and no one is interested in helping customers anymore especially us 69 year olds

Crew was very responsive to give soft drinks etc.. At Frankfurt Airport Special Assistance did a great job for us. The seat cushions were simply bad and not up to the mark for Premium Economy which we chose. All the cushions from Business to Economy were poor. Also, any snack besides lunch and breakfast, you have to purchase including chips and chocolate. It is simply cheap. I don't think I will fly Condor anytime soon

The short leg flight was fine. Crew and airport were nice to allow special assistance which helped.

Planes are new and clean and staff is attentive. Food wasn't great and chair cushions were very uncomfortable for long haul flights.
