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.

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.

You idiots…ITA cancelled our flights one month out and we had to buy new tickets at a much higher price. You stiffed us by not refunding the cost of the insurance. I’ll never buy through Kayak again.

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

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.

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

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.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

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.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Crew was not happy. Very uncomfortable seats. When person leans back in front of you the screen is too close to me. Food was awful.

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update
