Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

The seats needs to be comfortables, at least please add more padding to the seats.

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

They out me in the baby row so I was surrounded by toddlers, they also did not send my luggage and was not able to book my connecting flight

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

Dinner was fabulous. Would have enjoyed a wine with it. None offered... for sale??? Breakfast was disappointing but adequate amount of food.

Overall, the service was excellent, the crew verry professional, and departures and arrivals were perfect.

The service and food was excellent. The remote control for entertainment did not function properly.

Food was poor quality and the screens for entertainment didn’t work properly

One one boarding scanner was working to scan 400+ passengers to an Airbus 380. Food in premium economy was mediocre.

very small seats screen did not work . I could not watch anything for 9 hours

Very good experience. All of the details made this experience very positive.

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Flight LH760 from Germany to New Delhi, the food was excellent, the crew was fantastic, the seats in economy are usually tight these days, so I can say that the seats were Ok, the entertainment was OK because for some reason the sound is not very clear, overall I enjoyed this flight, compared to the flight (UA 962) I took with united from San Francisco to Frankfurt in this trip, that flight was horrible. Thank you Lufthansa.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Very helpful crew, including airport people, getting us in wheelchairs and working so hard to get us where we need on time!
