Pros: "Crew are always top notch, free drinks are readily available and entertainment system is great."
Cons: "The food portions and quality have definitely declined over the years sadly, as carriers cut costs no doubt."
Pros: "Amazing crew, excellent drinks and decent food. Very comfortable seat"
Cons: "Everything was great"
Pros: "Crew was great !!!"
Cons: "Seating in upper class is uncomfortable and bedding is not fresh."
Pros: "crew was nice"
Cons: "First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding."
Pros: "The flight itself was good! The one from London to Delhi was better than from JFK to London"
Cons: "I wasn’t told about my baggage were being delivered through different airlines the other day!"
Pros: "Food was delicious, consistent timely service and excellent entertainment options onboard. The flight was an hour early!"
Pros: "The flight felt so short, service was amazing, food was good. Great overall experience."
Pros: "Amenities"
Cons: "Bed was incredibly uncomfortable in first class. It was like sleeping on the floor. People talking loudly in the bar late into the night, which made it even harder to sleep. Didn’t sleep a wink on this 10 hour flight."
Cons: "I did not like the fact that my seat was between 2 small children that belonged to a family sitting behind me .It was ridiculous to put a stranger on a 10 hour flight with a 3yrar old on one side and a 5 year old on the other"
Pros: "Fast boarding and nice staff. Food selection was ok"
Cons: "One item missing from menu (unavailable). Issues with entertainment system. Bathrooms lacked moisturiser which is always very helpful on long flights where the air is dry"

I should've been inform it wasn't Lufthansa but United Airlines.

Pros: "The flight barely had a bump and was on time. Service was terrific and, for a regular economy seat, I didn't feel too squished. The entire experience was highly positive."
Cons: "I travelled economy and found the seats not very enabling for big and tall folks as myself ! Other than that I highly recommend flying Lufthansa"
Pros: "Everything that happened during the flight was fine. The service, the flight itself, and the landing – which was excellent."
Cons: "On the ground, neither the staff nor the signage made it clear exactly where to check in. I was sent to the Lufthansa counter, which didn’t open until 11:30, when I should have gone to the United counter. An hour of my time was wasted, which almost resulted in my missing the one-hour before take-off check-in deadline. The only reason I didn’t miss the deadline was because the flight was late taking off."
Pros: "Excellent service. They really brought around the drinks and food and seemed to be there when you were looking for more."
Pros: "I liked the seats, the space for our legs and the crew members"
Pros: "Crew was nice."
Cons: "This was an emergency trip to see my mother who was in the hospital. The flight was delayed so I had no option but to board the next day since I wouldn't be able to make it to the connecting flight in Frankfurt. They couldn't give me another connecting flight since it was all full. Because I booked my ticket only hours before my flight, they said it might not be possible to fulfil my meal request since there's a 24 hours cut off. However, now I had to cone back to the airport and take the next days flight which gave the airline more than 24 hours from my original meal request. I still did not get the meal I requested, the crew didn't know about it and didn't have any to spare. This was my first time flying Lufthansa, I probably won't try it again."
Pros: "The hospitality crew that was at SFO gave us the location of a lounge to go to which closed at 8 pm. The time they gave the location was at 8.25 pm. She was uninformed and not very highly trained. Lounge was disgusting. Messy, crowded - seemed like a 2nd class waiting room in an Indian railway station. The boarding was very poorly managed by the same lady!"
Cons: "Lounge, crew, boarding area"
Cons: "I haven’t received my luggage and I have been in Mumbai for almost 3 days!!! I have to buy new clothes and plenty of toiletries, I have only had 1 phone call from the airline to tell me my bags never left SFO!!! Wtf!"
Cons: "The crew didn't seem particularly interested in helping anyone and worked hard to avoid eye contact. This was an unpleasant flight at best and given the option I will not likely fly Lufthansa again if given the option. I wish that I had better news to report from this flight. :("
Pros: "Nothing."
Cons: "I'm still at Heathrow 12 hours later. I never made it to Oslo."
Cons: "Missing one suitcase and it will be delivered a day late supposedly"
Cons: "Club World is a super dated product. The tech is old and you are uncomfortably close to your neighbors. Also even when you buy a business class ticket British Airways makes you pay to reserve a seat in advance if you don’t have status with them. That feels over the top for a premium customer."
Cons: "BA is löst. This whole experience for a first class flight was a joke. SF no Lounge, food terrible, london lounge max BC level. LH 2x better, they need change"
Cons: "They did not give the gat no till the very end and the s cueing check was horrible when carrying a baby"
Pros: "Nothing"
Cons: "We waited in the plane for 5 hours and ended with a cancelled flight. We were rebooked out of Oakland the next day. Missed an entire day in Rome for our honeymoon, lost a night at a hotel, and lost money on a tour."
Pros: "The food, the staff and the free movie on the airplane."
Cons: "My American partner's passport expires 2 months after our return to the US. Unfortunately, the French issued a year ago the following rule: to enter France, the foreign passport must not expire at least 3 months after the return date. British Airways let us fly to London, explaining this to us, how it would be on us if there were problems further down, and that we would have to get our luggage in London. We chose to fly thinking it would be OK, we had listened to an online person who had had the same problem and the French later told him they would have let him in, also I am myself a dual citizen of France and the US, plus I am autistic, an invisible disability (in my case) that makes it impossible for me to travel alone. I usually do not even say it since not much is understood -by those who do not have it- on how to accommodate it However in London BA did not allow my partner to go on. Due to the fact yesterday was Easter Monday, the American consulate in London was closed. We have spent the night in a nearby motel and now, the next day, I am waiting alone back at the airport with our 2 large suitcases while my partner is at the American consulate. We are poor, do not have phone, currency or charger for England, and I do not do well with stress, so it is difficult. Now we cannot easily reach one another. We hope to be able to fly on a standby basis (that's what BA told us we could hopefully do) later today. Sorry for this long letter, I hope it does not bore whoever reads it (if it is even read :). Anne-Laure"
Pros: "I like that we didn't crash"
Cons: "They lost my and 5 other persons luggage! British Airways sucks!"
Pros: "Only one layover in London"
Cons: "Emirates, Etihad flights I thought were a bit newer and better in terms of comfort and entertainment with more charging ports etc"
Pros: "Crew were good , food was ok."
Cons: "Flight delayed again so both flights to USA and return were delayed... not a great experience . Entertainment took a cou0le of hours to sort, they had to keep resetting it"
Pros: "Flight was on time. They fed us two meals."
Cons: "Seats in coach are incredibly cramped, and blankets are comically small. The food was pretty terrible and the vegetarian option not particularly nutritious."
Cons: "It would’ve been nice if we made it to fort Meyers!"
Pros: "Only one screaming kid. I was allowed to move to another seat"
Cons: "Food was good. Crew nice"
Cons: "Three + hour delay out of ORD, equipment problems. Even though she had a boarding pass, they would not allow wife to board. Some ticketing problem between AA and BA. Finally, they let her on. We were the last to board."
Pros: "Quite new plane, clean. Some of the staff were friendly."
Cons: "Flight was delayed vecause there was no pilot for one hour. We missed connecting flight and ended up with several delayed flights, so our 11 hour trip turned out to be 32 hour long. Also, they messed up with food order, but after some time they managed to bring suitable food from business class. Some of the staff was unfriendly and whining. And our party of three was scattered around the plane, other families sitting nearby too. A little bit greedy company selling seat selection option when they could arrangeit nicely, but just don’t do it in order to get few people to pay for otherwise normal thing."
Pros: "A 2 hr delay after boarding with precious little communication from the crew."
Pros: "crew was great, plane seemed newer and clean. individual screens worked better than others I've used in flights."
Cons: "newer touch screens were great except viewing angle couldn't be adjusted. standard food was horrible, esp for an international flight; not sure if specialty diets have better meals. kid movies were dubbed into many language options but Chinese was not one for ANY kid films. bathrooms with the same crappy mini sinks that you can't really wash your hands in, esp if someone pukes in it. they should all learn from Japan's ANA airliners with the motion sensor sinks with faucets raised up high enough for you to wash your hands without touching the gross basin."
Pros: "Check in staff were very good.Lots of entertainment choices. Very comfortable seating,was worth the extra price."
Cons: "I went to check in with Iberia airlines as the flight information said. Desk was closed. Went to American airlines as suggested by airport staff, which was correct. Completely different terminal,we were lucky we had 3 hours between connections, the whole process took over an hour. Very confusing. The plane was American Airlines, Iberia was not mentioned anywhere else,very confusing. Dinner was served within an hour of taking off at 11pm, which we didnt have, but then nothing until an hour before landing and very hurried. Staff had been very busy chatting in the galley. No snacks available. Had a group of rowdy and rude passengers near us, not alcohol related. I think staff shoud have had a word with them, it looked like they didnt want to know, another passenger finaly did after 5 patient hours. Arrived in London, our bags did not. Staff were good. They found the error straight away. They delivered them to our home the next day which was a very good service."
Cons: "Having to step down very steep stairs after an overnight flight and then board a bus whose driver is not sensitive to the fact that many are standing when he makes right angle turns. It was cool outside as well and all my winter clothing was in my checked bag. I had not known I would be exposed to the elements at the end of the flight. I could have been warned!"
Pros: "seat was comfortable. flight almost on time food was poor"
Cons: "food was poor"

The infotainment system is liking compared to Airlines like Emirates Etihad Singapore Qantas

Cons: "My luggage was never loaded on to the plane, so I am in London with one pair of clothes. Luckily I packed my medication in my carry-on for this exact reason. The flight was very uncomfortable, and the food was terrible for anyone with food allergies. However, the crew was delightful and made up for the other unpleasantness."
Cons: "The queues at immigration in San Francisco were disgracefully long. it took us 3 hrs to get to our luggage. Advice to US govt to employ more immigration officers. Airlines should report on this"
Pros: "Food was delicious! Crew was very nice and friendly and plane was very clean."
Pros: "nothing"
Cons: "You need to spell out that when you purchase a BASIC ECONOMY fair, you will be charged for luggage and cannot change your seat. This isn't all spelled out in big bold letters when you buy on Kayak and the carrier treats you bottom of the class."
Pros: "The flight attendant in our section was amazing. She gave us tips for London and gave us some complimentary alcoholic drinks. She made the flight so much more enjoyable."
Cons: "The seat comfort was just ok. Neither my husband or I was able to get much sleep. The seats in coach are very tight and we couldn't really get comfortable."
Pros: "Flight attendants were absolutely amazing!!!!! They made the trip very enjoyable!"
Cons: "Food!"
Pros: "Seats were the most uncomfortable I've experienced in years"
Pros: "The crew and the food was good."
Cons: "Flight was delayed and one of our bags was left in London."
Pros: "I am Premier Silver on United, so boarding was easy and the flight attendants were very nice."
Cons: "When I purchased this ticket on Kayak, it was advertised as "Economy" and confirmation was also "Economy" however, United Airlines only recognized as "Basic Economy". This prevented me from using my free upgrade to Economy Plus. It also prevented me from selecting my seat and I got a seat I didn'"
