Business class seats felt very cramped compared to other airlines.

OK, we were delayed and had to de plane and reboard.

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

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

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

it was a very short flight so my expectations were low.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

Late flight Delays Poor service Poor staff Worst airline ever

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.

Everything was really great just The aircraft was too old and sounded it will break during takeoff

Extremely pleased with the crew. Best flight attendants ever! Very friendly, genuinely caring and attentive.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.
