It was was okay but the seat was stiff and hard to sit on it!!

6.0 GoodAnonymous, Mar 2025WAW - TLV
Read more LOT reviews

It was was okay but the seat was stiff and hard to sit on it!!

Seats were so uncomfortable, my butt hurts so much, I wish they have more cushions,it really was horrible, Except that, Stewarts were polite food was decent

The 737 lacked business-class seating. It was basically economy plus but with the middle seats left unsold. There were no TV screens but good food and service.

Plane is super outdated, seats not that comfortable for business class. Lounge also out dated. They need to catch up to 2024. Don’t think I’d ever fly again.

Boarding was impossible to navigate. Had mobility issues and a business class ticket, but still boarded almost at the end of the queue because there was absolutely no organization or assistance.

Aircraft was new. Food so so, especially vegetarian was very disappointing.

Very courteous staff. Abnoxious passenger in front of me who reclined her seat all the way without warning and without considering the person behind her. My flight ORD-WAW was so much more pleasant because of the courtesy of the passenger in front of me.

LOT told me on my first flight that I had missed boarding my second flight and told us to go to a service desk to reschedule. We then were told our flight was still boarding and that we had to run through the Warsaw airport to catch it which is just a long long runway airport. The workers at the airport were not helpful at all and you have to go through two passport checkpoints. I have asthma and was almost dead when I got on the plane and no one helped or gave us water or even acknowledged us. The flight was fine - the crew members are not friendly so it’s a very functional flight at best. Also my bag didn’t make it to my final destination.

Great service . Everyone is so polite and ready to help. I always was using Lufthansa but from now on I will use LOT. Thank you for your service.

Once again very friendly helpful staff A short flight but not only on time actually a bit early

Delayed 30 mins Forced to check in my carry on luggage

The biggest let down was with booking experience through Kayak. I booked a flight with checked bags on Kayak. Right away I got a message from travel agency that the flight is not confirmed and to call them. I called them and they said the flight I have booked is no longer available with the price I have booked it for and I can book it with about $100 more. I already had other options I could book with cheaper price so I asked them to cancel my booking. Then they said I can have the ticket with the same price but a date change which was not working for me as I had to be there for a seminar. So again I said no then they said they will cover the charges and confirm my flight. When comes time for check-in I see I have no checked bag option which means the travel agency deceived me saying I can have my booking as I had booked it. And at that point I ended up paying $155 for my checked bag going back and forth. I am extremely angry and unhappy with this experience

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

-Swiss airlines online check in app crashed multiple times -Zurich airport does not have very many bathrooms accessible to people with disabilities - closest disability accessible bathroom to departure gate was 1/4 mile away.

It is a good airlines, very professional very good food. I wish they offered free luggage is the only thing.

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

Nothing special.. they could have provided something to eat without a charge

Crammed like sardines into the middle of the middle 4 seat row for an 11 hour flight was a terrible experience. No attempt made to help passengers sleep by dimming lights or shutting window shades. Small mediocre meals. Not enough good movies/TV options. Hopefully we will never have to do this again.

Flight attendant served beverage to everyone during meal service and forgot about me. Had to call her several times until she realized it. Not a good service for a business class flight

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Usual issues with flight delay. Perennial problem of travel by plane.

i didnt go this was a hacker booked this flight on my debit card !

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

The flight was delayed by an hour. Made the connection uncomfortably tight.

Service was bad and food they told us they only had pasta very rude

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Delayed over 2 hours. Bring your own snacks or prepare to pay. No entertainment and no plug plugs for charging.

The flight was so FULL That I had to keep BOTH my carry on AND my personal items ON my lap while I was sitting there for 10 hours Because the airline put ALL the other stuff into MY overhead cabin Most uncomfortable 10 hours of any flight I

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

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

Pretty standard. Crew was helpful and friendly. Plane was clean and food was good.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

LCY airport is an amazing airport and I love the flight from LCY to FRA with BA. Efficient, easy, comfortable and great luggage allownace with BA. I iused to fly predominantley LH, but the service and price - benefit ratio of Lufthansa has deteriorated a lot over the last 5 years. Whereas BA keeps an excellent service level with friendly staff.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The airplane was old. Some things didn’t work out of middle seat was broken. The rest was OK.

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.

Very quick boarding. I was surprised we only got a small water and small thing of cookies, everything else was for purchase. No entertainment. Crew was excellent though.

Flight delayed in terms of boarding and Kayak was great in updating but the team on the groping at British Airways were really poor

A basic tea/ coffee and a snack could be provided especially for long distance flyers.

The information in the airport, and the app was different. Be aware. Different terminals in Stuttgart, so we had to walk a lot. It's a small airport so it wasn't a big deal, but it was ludicrous to see the error in the app.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Food was terrible , crew were excellent , IFE was dire . Overall comfortable seat and cabin. Nothing special .
