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

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.

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.

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.

I can’t even the whole trip was a catastrophe

I like how professional, fast and good the whole experience was.

Flight was very full and we had to checkin our carry on. Stuff however promised us that our luggage will be the first one to come out and it did

Delayed flight… caused the missing of my connecting flight in Zurich. Had to wait 10 hours in airport for new flight which was also delayed by 1 hour. No apologies and minimal compensation.

We were very impressed with Swiss Air. The service was exceptional. Unfortunately, we had a baby behind us that screamed for hours. , It was a nightmare, though I completely understand that it was not Swiss Airs fault.

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Basic flight. Great for something under two hours. Seats were a bit dated and uncomfortable

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Flight delayed 3 hours 45 minutes. Connecting flight changed. Would have missed cruise ship. Had to cancel return flight, because we couldn't just cancel flight to Nice.

First off, numerous things were misrepresented. When we purchased the Economy Plus tickets the fare allegedly includes access to lounge. At Logan Airport where the signs points to, there is no longer SAS lounge. We were directed to Delta lounge, which is located at the other end of the terminal. When we got there, Delta reps told us that it is for SAS business class passengers only. The advertised seat selection 30 hrs prior to departure did not work online. When I called SAS, they told me that it was more than 30 hrs before our connecting flight in Copenhagen, although it was less than 30 hrs before the departure for Copenhagen. Customer service representatives would not provide any assistance. The tray table in my seat was not fully unfolding to be able to place the food tray on it. Therefore, I had to keep it on my laps.

Everything went very smoothly. My only complaint is how cramped the seats are for an international flight.

They were charging $$$ for first glass of wine. That first glass should be included in such a high price.

Good could have been better. Comfort was fine with decent leg room and seat comfort. Would have appreciated a USB-C charger port.

TERRIBLE! Staff was unfriendly, rude, and demeaning. One flight attendant touched me to grab the complimentary blanket off my neck because I couldn't take it home, while a bunch of other people took theirs home. I have never been so ill treated. I am not happy at all. And flight was delayed, no information until short notice for everything. Lost an entire day at my destination. I expect a full refund for that experience. Never will fly with them EVER again

We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.

Well, I think we left close to on time. Crew was “eh”.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.

Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?

Food was very bad. Boarding was disorganized and messy. Crew was friendly

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

Entertainment was good. Food was mediocre. Service was mediocre. New plane was smooth

Staff was great. Space in bathrooms was very good. Boarding went smoothly due to aisles. I would like more room in coach. 2 more inches would be helpful. Lost luggage was a big issue; more on the administrative side than flight related, but diminished the flight experience.

Flight was cancelled and I got rebooked with anther airline. Also had booked a direct flight and got a layover.

The seats are designed for 12 years old, but pretty uncomfortable for the average adulte!!

Boston Logan is a crummy airport - signage is terrible or lacking in areas. Boarding seemed to be a free for all and with all the different airlines speaking, you couldn't tell who was supposed to be where and when. Plain and simple, airlines should board from the back of the plane to the front. Also someone was sitting in my seat. By the time that was figured out, I had to place my overhead behind me which made de-planing more difficult. Logan is not Lufthansa's fault so that is not on them, Boarding is on them! Still, overall it was a Good Experience flying with Lufthansa. This is not my first flight with them...

The Lufthansa part was wonderful. The short connection flight was not.

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent

The attendants were nice, but I was freezing the entire nine hours and so cramped. Please provide more blankets or make it known how to borrow a blanket for such a long flight. Even in already expensive economy class, people really need a bit more leg room and two more inches between seats to comfortably fly for 9 hours. Our family works very hard, but the extra expense of economy plus is just not in a lot of customer's budgets, and we still want to fly in equal peace and comfort. Please create future aircrafts that reveal reasonable care for us, the cramped- to- death customers more than the question of "how can we jam a few more human beings into this already cramped flight to impress our higher ups making a few more dollars. It's just Wrong. People need a reasonable amount of leg room and a blanket when the airline attendant said the extreme air conditioning could not be turned off. The food was tasty, but a bit more protein and less fluff would be appreciated. Thank you.

It was very good! Crew was very friendly, food was very good. I was on economy so the comfort was ok. Other than that, I would fly Condor again!

We had premium economy seats and the only difference from economy was legroom. Only one restroom for about 50 passengers was a little uncomfortable. Dinner was rather unpleasant but breakfast was good. Entertainment selection pretty good and you can use Bluetooth headphones. Flight attendants were okay.

Very cramped and uncomfortable for a large long flight! Not great service. My luggage was lost and is still lost 5 days later!!!

They lost my bag and have yet to find it, they won’t talk to me or give me any customer service at all. I’m now having to contact Alaska to help me because Condor won’t give me any updates and it’s been over 24 hours with nothing

I did not like that I was charged $ 60.00 for a window seat, 26A, and then assigned a middle seat, 44D, without any excuses.

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

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.
