Cons: "Considering that we’re in the middle of a pandemic no LH ground staff at Heathrow Airport was leading by example wearing protective equipment such as mask or gloves. Further, I found it inexplicably that almost every seat was taken on this flight. If LH knows that the flight is booked close to capacity I would have expected they do their part and due diligence by swapping to a bigger aircraft to help protect people and their customers, it’s not that they wouldn’t have other aircrafts grounded and ready to go... A reduced beverage service is all you can do, really? LH - very disappointing once again"

Pros: "Didn’t like anything. Mediocre all round."
Cons: "Disembarkation took 40 mins due to which most passengers struggled to catch connecting flights. Very poor service by Lufthansa to help delayed passengers."

Pros: "Nothing!"

Pros: "Boarding was quick and good"

Pros: "The flight was quick and minimal turbulence. Crew was friendly"

Pros: "There wasn’t anything to highlight as good. On this trip except LHR was organized and clean. The boarding was a free for all after the elderly and young had been boarded footstep as they should."
Cons: "The ground staff were rude and officious"

Pros: "Seat and crew were amazing but obviously struggled to be proud and confident of their job, can’t blame them if the company cuts expenses all over."
Cons: "When you fly business class, you expect a different product than economy, because you pay almost double the price. All we got is the same lousy sandwich as in economy, neither are alcoholic or hot beverages available due to ‘shortage of staff’ as the crew announces. A flight far behind LH standards."

Pros: "The Munich airport presented a startling contrast to heathrow! Both the flight from London and from Munich were very nice. I was so tired that I am sure I missed a lot."

Cons: "On tome flight"

Pros: "Nothing at all, whole experience was incredibly stressful"
Cons: "The transfer was awful. Long line for the frankly bizarre security check despite never leaving the terminal, incredibly rude staff at Frankfurt airport, all wearing may we help badges, so kind of answered their own question. Check in staff once we had sprinted th length of the terminal very rude"

Pros: "Crew very helpful."
Cons: "Both flights late. Food was worthy rather than tasty. Seats small. Too much plastic - why not use non plastic cups. Sexist safety card."

Cons: "The entertainment system broke down completely on the whole plane and the crew was sort of grumpy."

Cons: "Boarding by rows would avoid people rushing to line up ahead of time."

Pros: "Flight delayed- missed my connection"
Cons: "5 hour delay"

Pros: "Staff were ok, did all they could"
Cons: "Not enough information especially for people with connecting flights"

Pros: "Excelent service"
Cons: "I liked all"

Pros: "Despite the short flight we were still given food and as always I love airline food. Free alcohol is always a bonus as well! Nice crew and timely take offs and landings. Could bring two hand luggage (backpack and suitcase) which I like even though I didn't have to pay extra!"
Cons: "No negatives."

Cons: "There was not enough room for all the people’s cabin size luggage. They allowed people to get on board with big coats once they’re in the plain they take off the coats and place them up. Those coats take the same space as a small suitcase. I asked the fly attendants for assistance and they didn’t even pretend to care about the situation. I had to put my luggage under the seat for the entire flight, which ended up reducing the very reduced legroom. What this airline is trying to do is; to charge passengers twice for cabin size luggage. This has been my worst experiences with airlines. Lufthansa is definitely an airline to avoid."

Pros: "Very explanatory clear and responsive. There was a short delay they kept us informed clearly and responsibly. Excellent flight and superb performance. Very polite and helpful."

Pros: "Everything. The staff were absolutely lovely, the brand new fit out of the 777 is excellent and modern, the entertainment was great as was the food. Overrall really impressed."
Cons: "Nothing."

Cons: "Flight from Heathrow to Frankfurt delayed, when we arrived we had no chance of making our connecting flight to Split yet no one told us. No one at the gate which didn’t say final call (or on any of the boards) or anyone calling us over the tannoy at any point. Super rude “flight manager” A. Turini burst out laughing when we told him our situation and when I asked why he said “Well would it make you happier if I cry instead?” So unprofessional."

Pros: "The ground staff in Heathrow was helpful. They happily swapped me onto an earlier flight to Munich after I spotted delays out of Munich, allowing me ample time to connect in Munich airport"
Cons: "Lufthansa's narrowbodies have one of the most uncomfortable seats in the sky. These slimline seats are built with a central beam running vertically along the midline of the seat, making it very uncomfortable with your spine."

Pros: "Crew and service was amazing"
Cons: "No entertainment food Horrible"

Pros: "There was no communication between aircrew and gate for transfers. There is a new additional check between gates and no passenger was informed. This security check was over an hour long."

Pros: "I like everything about Lufthansa in terms of quality and service"
Cons: "Punctuality. I fly lufthansa twice a week and I have yet to fly on time. There are always a delay."

Pros: "Once again, the in-flight crew was excellent. The flight was good, but no entertainment is provided."
Cons: "Another late take off, probably because the incoming connections were late. So it was good that the airline delayed the connecting flights. However, this leg of the trip was so late that I barely made it to third leg of the trip. A huge problem is that each of these international airports require that you go through the security check again. For that reason, connecting legs of trips through these airports should not be scheduled so close together. Heathrow is the worst, with security staff that, at best, don’t care that you have a close connection to make and just ignore your pleas to speed up the process, and at worst, are just plain rude."

Cons: "Cancelled flight and transferring me on turkish airlines again the flight was delayed over three hours.,obviously we have missed our connection flight to Beirut and now waiting in front the hotel desk because the first flight to Beirut is 12:25 pm , I have lost 2 days from my holiday,I'm very tired and upset, I will never use kayak ever again and I will tell all my friends and family to avoid it."

Pros: "Only an hour and a half but perfect service and even a nice meal. Because of the delay there were a lot of questions to the crew but they managed to keep travelers calm and happy."
Cons: "Flight was delayed but that had nothing to with the crew and the service."

Cons: "The flight was delayed . When we arrived in Frankfurt, there was a quie of 200m . After waiting 10 minutes, they asked us to go to other passport control . We had to walk onother 10 minutes to get there ."

Cons: "Not entertainment at all"

Pros: "The boarding process was smooth, take off delayed by just over an hour but the Crew were exceptional with providing updates and bringing around refreshments whilst we waited."
Cons: "Seats were a little uncomfortable but outside that not much I can fault the airline for."

Cons: "I didn’t like it because when I asked for a big water bottle, they refused to gove it to me while I am sick and suffer dry throat. The space is rather small. If you are 5ft 5 and above person, I honestly would suggest you buy extra legroom for comfortable purposes. Also, there is like 1 restroom on the whole plane and if you sot at the end, you are screw. Lets not forget that they delayed our flights like 4 hours and only gave us 1 voucher for snack. I don’t expect the experience will be fancy but this is a total disappointment!"

Cons: "It took ages to go through the security check, although I have mentioned that I have a flight connection that is due to leave nobody gave a s..t, so I missed my flight. Now I’m waiting at the airport"

Cons: "Cancelled then delayed then had to stay in Frankfurt and was a day late"

Pros: "The environment was very nice. Relaxed and roomy"

Pros: "The crew were very helpful and friendly"
Cons: "The flight was delayed"

Cons: "Very very long walk plus train to baggage reclaim at Munich"

Pros: "On time and good service"

Cons: "Poor food on first leg. Sat by a man who was allowed to have 7 cans of beer. On second leg of journey I was willing to pay for food. The best choice for anyone trying to eat a healthy diet was pot noodles. Air Canada get 2 stars. Return journey on United gets 4stars."

Pros: "It’s nice that Lufthansa still gives food onboard"
Cons: "My Lufthansa flight left with 1hour delay"

Pros: "Smooth process. Regular updates."
Cons: "Late departure."

Pros: "Good attitude"

Pros: "Fast-track security, Lufthansa lounge in Heathrow T2 was fabulous, with incredibly attentive staff, flight stewards were extremely polite and also attentive. Great in flight snack and drinks. A real pleasure."
Cons: "The long walk at Frankfurt - but you can't blame the airline for the place the plane docks at."

Pros: "Friendly helpful staff."
Cons: "Delays."

Pros: "I arrived at the airport early and the check in staff offered an earlier flight so I wouldn't miss my connection. Crew was courteous and the sandwich on board was quite good"
Cons: "Slim seats very uncomfortable and legroom too little"

Pros: "The food and drinks was very good."
Cons: "The flight was late."

Pros: "It was good the checking desk person was polite and done her best to put get me on to British Airways flight to get to my destination on the same day."
Cons: "But we waited tilll 12.30pm still flight took off at 14.00 and arrive in Dubai at 23.50pm instead of 22.30pm person went home who suppose to pick me up. I got to the place I was staying at 01.39am which was very uncomfortable. I will never fly again with Lufthansa Airline it use to like British Airways but definitely they have lost the customer touch."

Pros: "Free refreshments. Funny cabin crew!"
Cons: "There was very confusing and contradictory information on what you can take with you on top of your cabin luggage. e.g. Can you or can you not take a small shoulder bag with you."

Pros: "crew at the gate really excellent"
Cons: "usual plane handling at Frankfurt - bus to terminal, 60 mins is not enough to wait for bus 15 mins drive 10 then go through security and passport control then go from B to A leaving no time to catch a plane Lufthansa scheduling need to experience what they do to passengers"
