Terrible plane small airbus good for a 1 hr trip I booked business as it is. A night flight and 4hrs trip it was an ordinary economy seat with no one next to me what a joke what a stupid decision to buy business

For the price of the ticket it's probably the best service in the world

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

Lots of water brought around by staff which is very important to stay hydrated on a long flight. There provided swiss chocolate icecream! The attention to detail is obvious. They really want to make their passengers entertained and comfortable.

I would recommend flying SWISS to anyone. Very impressed by the quality of food. The staff was extremely kind and accommodating. They arranged a shuttle to help a group of passengers make connecting flights when there was a delay.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

It was unclear that additional passport control was needed before boarding. The seats were cramped and uncomfortable even for small persons. The arm rests were unable to be lifted completely out of the way and the media controls cut-out made them uncomfortable to lean on. One audio channel was not working on one of our seats.

It was not made clear that additional passport control is needed before queueing up for boarding. The seats were very uncomfortable and cramped even for small persons. The arm rests were not fully capable of lifting up out of the way and the media controls cut-out made them even worse to lean on. Just one audio channel was working on one of our seats.

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

Stuff was very helpful at checkin. Flight attendants were nice. Food wasn’t very good, I expected a little more. Economy Seats are ok. Second flight was very full and they forced us to checkin our carry on.

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

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.

LOT was very disorganized at Istanbul airport with no communication with travelers. Our flight was delayed over and hour and a half and there were no announcements, displays or anything about it. It almost left me missing my second flight!

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

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

bus ride to the plane was very crowded and had to wait a long time to get to the plane. The flight itself was great.

Together with my family, we all agreed that the LOT crew provided the most wonderful service that could be. We are grateful for such a great experience they provided to us! We will return and share our experience with all our friends and family.! Keep up the good work!

Flight WAW-ORD flight attendants were really rude, no smile at all. Except one young girl working in aft part of the cabin. They were talking only in Polish. After 4th/5th time asking in english, they were answering in english. Not the best approach to the pax.

The flight was very bad, the food and the staff was very rude. My last time with them

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?

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

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

I was charged at the gate for bags I had already paid for. There was no other option. I am trying diligently thought easyJet website but making no progress HELP!

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

Nothing! The service was excellent for accessibly challenged passengers, Used lift and all support personnel very helpful. Will fly again.

Worst airline in the world, will never travel in it again.

Flight crew was among the best I’ve ever seen

The business class seats are very narrow for the cost

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

Sun express is great. Frankfurt airport is the most horrible airport there is

Absolutely the most awful experience in the history of service from gate agents to baggage handlers. Never will i use kayak or Lufthansa again. Ever.

The airplane, although a very new model, does not offer a standard outlet plug, so when my computer battery died after 2 hours, that was it. It seems bizarre that they would offer only USB outlets.

No internet, very narrow seats insufficient room for three passengers with encroachment.

Lufthansa has outsourced their ground crew to a company in Bengaluru. This company is really not dedicated to customer service. Very disappointed as this does not reflect Lufthansa’s service that I remember from before.

Entertainment system have to be updated. Allied partners charging money for alcohol - in fact international flight.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced
