Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Complimentary light meal would be appreciated. But great flight crew service on all legs

The food was terrible this time. Otherwise pleasant, quiet, on-time.

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

They set someone on our assigned seats and we ended up finding seats for ourselves to ensure the family sits together.

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

The food could be better, more snacks. And have some plugs to chargue the phone.

Second time I took this flight, and they lost my luggage both times. Waiting for my suitcase now, last time it took two days to get it back.

Used to love Lufthansa, but Rowe are too close together in Economy and passengers are allowed to recline their seats so far back it is impossible for those behind them to even reach for carry-on essentials during flight - except for meal service when flight attendants ask for seat backs to be raised, we can’t sleep on planes so this flight was most uncomfortable ever!

There were several delays in boarding. Then our group wasn’t called. Good thing we went up to the counter to see what was going on. We boarded next and last. I felt sorry for the staff but that was our third flight to get to our destination and we were tired.

The food could have been better. Had a wide range of entertainment to choose from.

I was traveling with a young child and the flight attendants were rude and unhelpful when simple requests were made like an early cracker or cookie to help distract him while everyone else was boarding. Also, my wife received dirty looks from an attendant when she asked if she could get by while holding our crying infant. They made us feel like a burden instead of a paying customer. The food was really sub par, especially the breakfast sandwich; cold, soggy veggie sandwich with no flavor (zero seasoning or vinegar or oil) and as mentioned the bread was cold and soggy wet. Also, there seemed to be something wrong with one of the bathroom’s ventilation, the smell was terrible throughout the entire flight. In the past Lufthansa had a good reputation for customer service, they are actively destroying it with how they currently treat passengers. If our return flight is as bad we will never fly Lufthansa again.

Dear Lufthansa, thank you for the excellent flight. We arrived early which really helped us with our connection. Crew was so nice!
