Other than the toilets it was great. One was broken and another wasn’t flushing by the end of the flight
Premium economy was very comfortable with excellent service and legroom. On Kayak I was able to find a very affordable discounted fare
Overall seamless flight from SFO to FCO. I chose economy to have more money to spend while in Italy. The seats bottoms are a bit on the thin side but they give you a pillow and blanket so Inl used the blanket to thicken up the seat bottom. You have to have a physical boarding pass (at least for my flight) so that was interesting. Crew was nice, food was good and over pretty down the middle.
1 1/2 hours delayed boarding at JFK caused us to almost miss connecting flight in Rome. Only 30 minutes of time to run from one end of FCO to the other for connecting flight. Not very easy to do for older travelers.
Staff was nice but seat is not what I expected
Flew Premium Economy. The seats were comfortable and tilted back far enough to sleep. Food was okay and service friendly and efficient. We bought tickets through Kayak partner Underpricer and the price was good.
ITA has these new Airbus A330 Neo that hates economy class passengers. The seats have absolutely no cushion to a point where it hits your spine constantly and reminds you to fork out for premium economy or don’t travel next time. The food was absolutely horrible, ETA mentioned 3 meals for 12 hour flight but it was mostly 1 meal and 2 light snacks. I am vegetarian, so my 2’d food was 1 slice of tomato, 1 cucumber on a dry cold bun. The other 2 meals were disgusting. My young one threw up the entire time. Flight attendants were the cherry on top - plain bad. They would skip servicing drinks to some passengers completely and if you call for an attendant, they will come and stop the button on top without even asking you what you need. I would avoid ITA by all means - there are plenty of options including SAS for same routes with better seats and humane treatment.
Nice flight. Uneventful, very good crew, comfortable seats. Pleasant experience.
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.
When I fl with Bulgarian air, I am greeted with a bottle of water and a packaged cleaning wipe. There is a hot sandwich and a drink offered afterwards. Towards the end of the flight, there is a piece of chocolate and per request an additional water bottle. For the price that Lufthansa charges per ticket, it is embarassing that other airlines can offer better customer service quality on board. Also, some of the Lufthansa flight attendants act very entitled instead of being customer focused. Regularly the mobile lift for diabled passengers is missing... Every time when I fly with my 89 year old mother, she is being questioned multiple times whether it is okay to use the stairs ( she walks with two canes). Most of the times when we arrive in Frankfurt, the mobile lift is missing and she is urged to use the staircase. When I refuse to allow this, the flightattendants look at me scornfully. This is not WW2 where disabled people should be treated as second hand people... Then we all have to wait another 30 to 40 minutes on the airplane, while waiting for the mobile lift to arrrive. Does Lufthansa have enough money to waste on an airplane waiting for (on the average) 30 min for the mobile lift to come? I fly frequently and have experience mostly with Delta, United, Southwest and other American Airlines. Lufthansa needs to pick up their game on board, if they want to stay competitive and in the game...
Keep an eye on your seat assignments - ESPECIALLY if you paid for upgraded seats - the airline moved us out of our prepaid seats THREE TIMES and I could only resolve it by calling customer service - who was very helpful. Expect to carry your bags down several flights of stairs for boarding on the tarmac.
It was ok no problem on flight after the ordeal with passport control. Long line and nasty officers not very helpful.
I was disappointed that paying nearly $5000 more for business class for two didn’t really get me any more than a larger seat which as the last row in cabin reclined only mildly and the foot supports were of minimal help and left no room under seat ahead for carton bag. Second, our checked luggage was lost and took us two long days and we’ll after midnight each of them and multiple calls and 30 euro trip to airport in person to finally get them. Would you do this again?
The tv and remote didn’t work. The plug to charge our phone didn’t work.
Never made it to Lufthansa because of Air Canadas negligence.
Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.
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.
There is more space in this economy seat. It felt like a better layout, not so cramped.
Lufhtansa has and can do better. The food was inedible. No individual light for reading.
