Flight was smooth and event less. The crew is very professional, good looking and efficient. Food quality is good but the bread rolls (made in India) were too hard.

Flight was smooth and event less. The crew is very professional, good looking and efficient. Food quality is good but the bread rolls (made in India) were too hard.

Staff was nice but seat is not what I expected

The cleanliness is the business class continues to disappoint. There was food on the floor when I boarded.

The business class seat would not recline. Not acceptable for an airline and airplane that is relatively new and a flight that was over 12 hours. Very bad experience.

Comfortable flight Attendants are professional Had a luggage delay at one destination but was delivered the next day

ITA cancelled fligh rebooked with Lufthansa. Flight good, but 2hour connection in Frankfurt was HORRIBLE, took 1.9 hours to get through scanner, customs, another security, got to gate after running all the way, so caught it but stressful and terrible start to trip.

Flight was canceled. Rebooked on Lufthansa Also Canceled. Had to pay 3000 more per person and fly Alaska to EWR and fly emirates to Athens.

The flight I initially booked from Los Angeles to Florence. I made sure had a layover of about 90 minutes in Rome, so there’d be enough time to connect. A couple weeks before the flight for some reason I was updated that that flight had changed and I was only gonna have 60 minutes to connect. From LAX we were delayed by 45 minutes meaning making the connection was unlikely. The crew informed me that my connecting flight would not wait and they would rebook me on one four or five hours later. I wasn’t happy, but I accepted it. It is what it is. Except when we got closer, two separate flight attendant approached me eagerly and said they had great news that my connecting flight would in fact wait for me, but I needed to hurry through the airport so they didn’t have to wait too long. I was first off the flight. I ran about 4000 steps. And got through passport control all in under 15 minutes. When I arrived to my gate, I was greeted by a flight attendant there who was completely indifferent, said they didn’t hold the plane and they just closed the doors. Had they even held it for two minutes I would’ve made it. She simply told me that the flight attendant on my flight lied about the plane being held, and that they do it all the time. These were all employees of the same company ITA. I was absolutely livid at her indifference and having been lied to and then having to wait five hours and waste a day in Europe at an airport.

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

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

The tv and remote didn’t work. The plug to charge our phone didn’t work.

They set someone on our assigned seats and we ended up finding seats for ourselves to ensure the family sits together.

Food choices limited & not enticing Seats quite uncomfortable & difficult to control

Excellent service; they helped me reschedule so I can fly in an earlier flight

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.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

Seating was average for a first class seat. It very modern. I expected better.

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

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.
