Just kinda of a bus ride … we could do better. Delay in the flight :(

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes

They delayed all our flights and lost our luggage flying to Tokyo, Japan. Worst experience I have had with any airline. DO NOT BOOK.

They did great as being my first time flying with them I will consider flying with them again on my next trip.

1. Nowhere to sit at the gate D4 2. No control of lining up in different zones 3. People pushing in during the line up of zones. 4. Certainly not in a dignified manner.

Both meals (chicken option for dinner and omelette for breakfast) were lacking in good texture and taste.

The experience with air Canada, was not really good, first they try to charge for the seat again in the counter after being paid in advance, second we have to wait for a hora inside the plane before departure for mechanics problems

It was great. Although when I got my luggage it was broken.

Flight was delayed going and coming from my destination for over 5 hours. All I was given was a $15 meal voucher that wasn’t even able to cover my lunch or dinner.

Air Canada was great! From the airport at Montreal to boarding to the food on board the plane. The crew was great too! There was a slight issue with some other peoples’ tickets that I overheard about but the crew handled with care immediately to ensure everyone was comfortable and we could takeoff! Great experience with Air Canada

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

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.

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.

The flight was ok, the flight attendants were lovely, the movies were good, the food was ok, and I am just sad because my luggage didn't arrive with me in Iasi because the flight from Vancouver to Frankfurt was delayed and then I barely made the rest of my flights. Also, there was no real support once I got off each of the flights. There was nobody to ask about gate or where to be and for example when I got off in Vienna to catch the flight to Iasi there was no screen where I could read the gate and time of departure of the plane. I was going crazy trying to find the plane to Iasi and I barely made it. When my luggage finally arrived home it was broken. The handle was completely broken and that was not so good. I am in a visit here, in Romania, and I will have to buy a new luggage.

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

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

The flight crew, the on-plane service, and the food were fine. The seats lacked cushioning and were uncomfortable compared to other planes from recent flights. The plane was initially delayed one hour and that expanded to 1.5 hours. When we boarded, there was insufficient room for our carry-on bags, which added more time to disembarking from the plane. It appeared the Air Canada staff or the Toronto Airport staff were less than competent to handle whatever the issue was that caused the delays, which was never communicated.

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.

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.

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 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.

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

If my tv wasn’t broken and I wasn’t in a seat that didn’t allow for sleeping

Very long and took extra push back to BA staff to get a realistic flight after they made me miss my original direct flight. Eventually landed 9 hours late and incurred many extra costs with other missed bookings

They overbooked the flight by 3 people. It is completely unacceptable to tell 3 people, with paid tickets, that need to get home for children etc, that they need to stay another night. No compensation. No apology.
