Flight was delayed at airport with large backlog and WiFi was spotty

Flight was delayed at airport with large backlog and WiFi was spotty

I don’t like mushrooms and that’s all they had with pasta

I Love Delta but one of the flight crew training in courtesy snd hospitality.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Could have been on time and not missed my connection

Really hard to tell what was happening after my flight got delayed five times

Flight was delayed from San Diego due to being overweight for weather conditions. We missed our connecting flight to our final destination due to the delay, as well as the connecting flight leaving before the scheduled departure time. We missed the connection within 10 - 15 minutes. We were booked on a later flight arriving 7 hours later. There were 7 passengers sharing the same originating and connecting flight.

Horrible, mismanaged ground issue resulting in a long delayed, next flight left early, waiting extra 7 hours in the airport, screen did not work

Wifi on this flight was very sketchy and not available for most of the trip.

I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

Flight was on time. Could have been a little more comfortable. Baby cried all night.

The chicken on the flight Boston to Zurich wasn’t very good. It was bland passable. Too much sugar in the Cole slaw. Cabbage is an amazing veg and can be much more crisp and alive. Flight attendants were Wonderful! Seats were a bit beat up but okay. In economy it was tight when the person in front learned back the screen became too close.

On time and my bag made it. My parents on British Air had their bag held/lost at LHR, so Swiss definitely won that contest.

Wonderful, i asked at front gate to change my seat up closer and they gave me a row with no one in it. Very kind of them as the flight was on the light side.

Great crew, great food, horrible aircraft seat spacing for a 9 hr flight.

The food could have been better but everything else was superb.

Terrible airline both Swiss and Lufthansa that are part of the same corp. stay away if you can

The flight attendants are amazing. The plane itself was not in good shape for passenger comfort. A good share of seat reclines were broken so they went back an unlimited amount, which meant the person in front of me was fully in my lap (the crew helped me find another seat but that would not have been possible on a full flight). Moisture from the ventilation was also dripping on me. And the entertainment system is almost impossible to hear.

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.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

We were forced to eat vegetarian food because non veg food ran out. The breakfast was mediocre.

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

Aircraft was noisy, old and never dimmed the lights on a night flight even on business class! I flew 17 times on United and probably another 40 on other airlines United USA /Europe flights were the worst to include luggage delayed once going to europe and once coming back

Flight was delayed from 35 minute delayed aircraft arrival to 90 minute delay causing us to miss international connecting flight on SWISS resulting in 16 hour delay to reach detonation causing significant angst, monetary loss and discomfort. SWISS transfer desk and staff was like robots not willing to help at all.

Not the best. Mean. Didn’t give any value to me being a united silver member and lots of attitude.

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

my seat got changed twice after checking on then boarding it had been given to a family so by the time they found a seat for me no overhead storage left. i ended up losing my Sony Headphones case because i could even access underthe seat in front of my when deplaning.

Nothing exceptional but all good. Business class seats are like the domestic Mint class on Jet Blue. Comfortable but not exceptional. Food is good but not superb. Flight attendants were better than US carriers but that is to be expected. However, not the caliber of Asian or Middle Eastern airlines. Very Lufthansa like but Lufthansa has slightly better seats, even though they are hardly best in class

Seat 14K (business class) had no cushion / would not inflate. It was like sitting on a stone bench the whole flight. Sleeping was impossible.

TV wasn’t working, flight attendants never came when turning on the light, luggage was delayed and when delivered it was broken. No suitcase for the rest of our 2 week trip with no response when claimed filed

Lost our luggage, now two days and four $30 each taxi trips to airport and long lines in taxi queue because Lufthansa didn’t get it right, by not recognizing new delays between flights caused byEU new lengthy crossing requirements for non EU travelers, so luggage lost because traditionally methodical and orderly Germans not paying attention.

When our flight was canceled and rebooked, my husband's meal request was not transfered. As a result, there was nothing he could eat for dinner and breakfast on the new flight, save a side salad and roll.

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

Cancelled - booked on train; and then flights started running! I spent 5 hours with 2 changes on train while flights started and is 50 min

I’m glad the bus waited for me to connect me to my next flight since we were delayed. Flight was good.

More legroom (I am 6’4”) and my knees were in the back of the seat in front of me. Food was laughable

The flight was cancel and then changed the gate 3 times and nobody communicated to that change I don’t take any trips whit that company

More than 40 minutes of delay, the crew even didn’t apologize or explain the reason why we are late, no service for a short flight

The chairs are terrible on the plane, even though they are economy class the chair cushion should still be there, its a long flight its like sitting on a piece of wood.

I didn’t take that flight. My original flight was cancelled from Los Angeles. They rebooked me following day through Montreal My flight was LAX to YUL and YUL GVA

My flight from Zurich to London was delayed 2hours and 45minutes. It was awful.

Club Europe is always lovely. I really enjoy everything about it. One thing that has changed in recent years though, is the swap to Prosecco from Champagne in the lounges. This is really disappointing. I really don’t like Prosecco, and always looked forward to a lovely glass of champagne in the lounge. Is it possible to change back? It does make the whole experience a little more of a luxury experience.

They need to improve their service at the airport. Rather than a bus, they need to park the plane at a station like normal airlines to so passengers can just walk out of the plane into the airport and catch their next flight

Flight was cancelled at the last minute with no explanation. No viable alternative offered and zero customer service support. Totally useless.

My experience was very disappointing. Firstly I was unable to check in using the kiosks. Secondly even though I purchased a flight with one checked bag, I was told at the counter that a checked bag was not included in my flight booking. And I had to pay for my bag. At the check in counter, the airline representative was very arrogant and demeaning. She insisted on charging me £140 for the luggage. And said it was an automatic charge calculated by the scale. This didn’t make sense to me. As it was 0.5 kg overweight. Which only required me to remove 2 bottles of water. Having an extensive flight schedule that involved multiple flights included NY and Brussels, this leg of my flight was the most stressful and unpleasant.

My luggage never arrived to Zurich. They can't confirm when it will arrive

Updates from pilots about delays would make them less frustrating.

Almost 3 hour delay. First because the crew was late. Then a technical problem with the airplane.

The crew was great but we sat in the plane for over an hour before takeoff combined with a 4 hour delay on our previous flight caused us to miss planned scheduled meetings in Geneva.
