Fortunately the departure was delayed as I had a tight connection and the incoming flight was delayed. The departure delay helped me to make my connection. Thankfully, my luggage also could be transferred in the same time. The aircraft had to be changed and the power outlet in my seat didn’t work. Again luckily as the flight was not full, I could move to a different seat where the power outlet was working.

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

The already delayed flight took an hour to find no-show passenger bags, which seemed long. Flight attendants only provided flight transfer information to a few passengers not all.

Even though I flew in business cabin I was not given any refreshment even though those next me were served

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

Wonderful staff. The boarding process can be improved a little better by adequate prior communication but all in all they did fine. However the boarding gate was quite unfreindly to elderly and who needs help with sevral stairs.

1. One of the crew who was managing the crowd in the business class line specifically asked me if I am travelling by business class while I was standing in the business class designated line. She specifically was asking only me and no one else. Seemed to imply that I may not be aware of it and may be I don't belong there?(Based on my color?) 2. The business class seats in the aircraft was average regular economy seats with middle seat kept free.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

The service was fabulous and the food was excellent. My luggage was left in Frankfurt due to late arrival but it is supposed to arriving on tonight’s 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.

Nice flight. Uneventful, very good crew, comfortable seats. Pleasant experience.

Stews were nice. Plane was very old. Some of the mechanics for travelers outdated. Not enough bathrooms. Hideous food.

Our flight was changed to a day we could not travel so we cancelled it. Will never use kayak again

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.

The boarding process was organized and efficient, and the crew was friendly and attentive throughout the flight. Food and drinks were typical economy class, but good. The aircraft was old, and the restroom was not very clean. However, we arrived on time, so overall the experience was good.

In Prem Econ, safe and timely flight, good amount of space, mostly comfortable seats. Little irritants: When lying down, seat kept shifting on me...as a short person w/light weight, my seat often reverted to semi-upright. Footrest was broken. TV screen didn't work, after I asked a few times a FA rebooted it to work again. And food was marginal. I don't expect much from airplane food...surprisingly, ITA didn't even meet expectations.

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.

Our flight was cancelled the day before our trip and we we put on a Turkish Airline flight that got us in half a day later.

Everything is smooth without canceling the flight or long delay. We're happy about it.
