Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

toilets could be cleaned more frequently, everything else was pretty good.

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

I was traveling with my 3 minor children, one leg I was seated two aisles behind them. On the longest leg I would have preferred sitting across the aisle from them, not behind. My youngest is 4yos. I understand airplane seating configurations are not the airlines problem but seating the one adult with a reservation apart from the minors was very difficult.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Left hr late & arrived 1hr late luggage was slow to be offloaded! The flight crew & food were good! Movie selection was ok!

Seating wasn’t good at all with not much leg space in between. Fortunately it was a relatively short flight. Otherwise we would have struggled a lot. On board meal was pretty ordinary. It is sad to see the overall quality of this once superb airline has dropped so low.

Everything worked smoothly, never had a concern with the flight from start to finish.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The cabin temperature was nice and cool. The wifi was not working.

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

First flight out and was 85 minutes delayed. Notification came out way too late

The flight was cancelled, so why are you asking me how the flight was?

Fortunately the departure was delayed as I had a tight connection and the incoming flight was delayed. The departure delay helped me to make my connection. Thankfully, my luggage also could be transferred in the same time. The aircraft had to be changed and the power outlet in my seat didn’t work. Again luckily as the flight was not full, I could move to a different seat where the power outlet was working.

The entertainment is pretty boring. There are no new movies or TV shows from February. The food is just ok on the Atlanta to Frankfurt leg, but better on the Fra to Bengaluru leg.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Charging for reserving a seat is really cheap. The seats in economy are very small especially when the passenger directly in front reclines their seat. On long flights they should have coffee/tea and juices available for passengers. Here we have to bother the crew. Other airlines just put drinks and snacks in the back for the passengers.

This is the worst part of the journey. The Lufthansa flight was delayed, and I missed the connecting flight. Lufthansa staff have not been helpful in rebooking the subsequent flight with Air India (another airline that is part of the Star Alliance). Lufthansa told me it's not their responsibility, and Air India says the PNR is part of Lufthansa, so they are not responsible for rebooking. Lufthansa customer service asked me to contact the counter at Delhi airport, but no one was available there. I am caught between these two airlines, and ultimately, Air India decided to reschedule my flight after 18 hours. I am stranded at Delhi airport. I can't go out because if I do, I can't come back in, and I can't get past security to get food. My 3-year-old and I are stranded here for 12 hours without food and water.

Food could have tasted better and had more options - they ran out of vegetarian options. Considering this was business class, I don’t think that’s acceptable.

You should change everything like maintaining cleanliness ,food is very bad and staff doesn’t care their passengers and there was no water in the washroom whole flight and lastly entertainment is very bad headphones won’t work as well. So basically you should change everything in your flight. I think l’m not going to travel in Lufthansa anymore. Very bad experience

Worst baggage handling system. Our bags were delayed and multiple calls to customer service agents didn't help. The customer service is really poor and do not provide any update. The airport ground staff also are not helpful in terms of providing right information. False information was provided that the bag has not reached SFO.

Lufthansa keep delaying flights, my 26 hour journey became a 46 hr. No empathy from service desk just take it or leave it attitude
