ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

They lost a bag and now our vacation is ruined

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

Flight details on public information screen were misleading and wrong.

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Was very good the flight, 15 minutes late,but was very ok!!!😊👏

Long delay was made worse by lack of information and long time in queue waiting for the plane to arrive

How terrible! Extremely bad! I can not even wait for 5 minutes, because the Berlin airport does not work in the security facilities and can handle people. No communication, although we were assured by about 50 travelers that the airline is informed and is waiting for us.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

You have improved through the many years I have flown with you. But you still nickle and dime your customers. I paid extra for carry on and priority boarding.

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!!

The flight was great. I don’t know about the food because I was asleep and they didn’t leave me any.

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.

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.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

Did not fly to Houston as original flight was cancelled.

There is more space in this economy seat. It felt like a better layout, not so cramped.

The staff was not at pleasant as those on the first leg of our trip.

Boarding delayed 1.5 hours. Ended up sick because of all the delays and lines waiting around airport and boarding.
