I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(
I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed
It was a great flight Food was great Crew was spectacular
In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.
Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience
Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold
People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall
The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.
Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline
Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better
No towels or tissue and chocolate and mint provided before arrival
Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it
It was good no problems made it on time for the next flight overseas!
They made us deliberate waste time by holding our passports and boarding passes making us miss the flight
The made us waiting and held our passports and boarding pass making us miss our flights
Not impressed. Only allowed one carry on on such a long flight.
The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.
Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.
Wore experience due to delay and took me 3 days to reach my destination.
Bordón could be bettet if the company say before boarding the order of the different groups.
Checked in is easy and it was a smooth flight from LAX to Munich
There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.
The Lufthansa part was wonderful. The short connection flight was not.
German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.
Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again
Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.
It was a busy flight and all the crew were very helpful and gracious
Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent
Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.
