A true budget airline experience. Had issue with luggage tag needed customer service assistance, but there was only 1 agent open for the entire airport. ONE! Almost missed my flight because of that.

A true budget airline experience. Had issue with luggage tag needed customer service assistance, but there was only 1 agent open for the entire airport. ONE! Almost missed my flight because of that.

Always select priority to be able to take carry on luggage and board first without hassles.

Shady baggage policy that forces you to pay more money at the gate, even after you checked your bag dimensions during the bag drop. Will never fly again with this airline.

The plane had only a few passengers, we got lucky. The crew was visibly inexperienced

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!

Boarding at Birmingham was appalling, made to stand in a corridor which claims to be a gate for an hour, despite knowing full well the flight was delayed….. the crew were fantastic and you have to feel sorry for them dealing with the delay caused three fold, inbound delay, damage to front baggage hold door and finally a further ATC delay. On board experience was good and crew friendly and helpful.

Never have real problems...very ho prices for good the rest is all great

Flight was delayed which happens but walking 15 mins to one gate to be then told it’s now changed to one 15 mins back then other way was frustrating

It got us their! Delays Delays delayed, flight got in well after specified time, rental car firms shut at 11pm!!!! So from £300 for car to £689.. thank you Ryanair....

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

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.

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

Crew was excellent. Sat us together after the airline changed our seats. This was the smaller plane/shorter flight so no entertainment or food.

Boarding was one hour late. Gate notification was incorrect (notification said gate 17, actual was gate 14). Took shuttle bus to board the plane. Late arrival of plane at Turin impacted travel arrangements to the event.

They canceled our flight right before it was to take off and then we stood in line for four hours to make other arrangements. It completely ruined our trip.

Flight boarding was delayed. Old, low capacity overhead bins requiring many to gate check their carry-on luggage. Beverages other than water were at a charge.

Flight was cancelled and I didn’t arrive until 11 hours after I was scheduled to.

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.

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.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

Boarding to the plan was smooth. The plan itself was fine but the entertainment system work only on some seats (in our 3-seats row area only one seat had a working system). Landing not on a shoulder is very uncomfortable (departing the plan and travel in buses like it used to be 35 years ago)

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.

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.
