We ordered a gluten free meal and never got it!

The seats are horribly uncomfortable. We were in premium economy and paid a premium price yet, the seats were the worst! You could feel every structural bar in the seat, there was no padding, no amenities kit, and the leg rests were broken. Duct tape was holding another seat together. When we arrived at our final destination, Venice, my suitcase was ripped open, and my clothes were about to fall out of the bag. I would’ve been more comfortable if I flew a paper airplane across the Atlantic.

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

Seats weren’t comfortable. Both of our seat backs were either almost straight vertical or laying back into the laps of the people behind us, which is a weird angle to try to get some sleep even on a plane. No in between. Also, neither seat would spring forward like they should.

The flight was great, smooth and even a little ahead of time.

There wasn't a time for neither food morning entertainment in a short one hour hop over.

Flight on time, flight assistants super nice, business class very comfortable. The whole experience was very good.

It is the worst ever airline. All employees I spoke with over the phone were pompous asses.

The gate information was never populated on the Delta app or the airport displays or the desk at the Delta lounge. We found at the last minute that we had to switch terminals and just made it to our flight. Even this we found accidentally by asking an employee at another gate. On board service was poor. Seats were very poor. All in all a poor experience. At best like a Premium Economy on other airlines

No online or self check in. Sent emails in Italian language. In general, not recommended airline company.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

My flight was late from US to Frankfurt so I missed my connecting flight flight and I had to wait for long to catch the next flight which was very tiring. Otherwise everyone was very nice.

Everything went really well. Snacks could be better and there was no tea/coffee service after dinner. Crew was helpful and friendly.

Lufthansa charged me $280 to take skiiis when in the US the boot bag and skiis are one check-in bag. This was not advertised and a real shock at the airport. They only took the boot bag as a check-in item. The seats have been squeezed together like any economy airline and legroom is not as good as it used to be. Otherwise, the flight was fine and staff was helpful for making my connection.

Professional crew and staff, very organized boarding and on time flights, baggage handling. Indian vegetarian meals were good, though could improve by offering Indian bread (naan/paratha/roti) as well. Very helpful pre flight emails with details of onboard experience 👍 Above average selection of movies. Consider offering more movies with subtitles and ratings indicators (e.g., IMDB scores).

Terrible experience. Should be a short simple flight from San Francisco to Palm Springs. Disgusting insult that United Air doesn’t have a cabin crew ready to receive a plane that’s already an hour plus late in departure. Lots of misinformation along the way from cockpit and crew. Definitely unimpressed with both union and management.

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

I requested a wheelchair for they haven’t got it, they are old and don’t speech english

Good but entertainment system was not easy and very buggy
