Horrible. We arrived at 5:30 a.m. to check in our bags and go through security to fly out at 8:10 a.m. Upon waiting for 45 minutes in line to check our bags, we got to the counter and were told that we may not be able to be on the flight (it was not over sold but over weight?!). For whatever reason we were told to step aside and wait until one hour before departure and that someone would let us know if we’d have the privilege of getting on the flight we paid for. As an hour passed, we got back in line and hoped for good news. After getting back to a counter representative, the initial employee we spoke to abruptly interrupted the conversation and in a frustrated/annoyed tone demanded we go back to the area off to the side. I mean, I get that they’re inundated with passengers of all types and are under a lot of stress themselves, but getting reprimanded like a child to be put in time out for my blood boiling. How were we supposed to know anything when we weren’t given any details. As the clock ticked away, the time to depart was fast approaching when an Air Dolomiti informed us that we would not be able to fly. In fact, they would have to rebook us and find us alternatives. Long story short… we ended up being told our only option was to take a bus from Florence to Milan and a plane from Milan to Munich. Our trip, which should have been us arriving at 5:30 a.m. and landing in Munich at 9:30 a.m. turned into an ordeal of waiting… waiting… taking a near 4 hour bus… waiting… an hour flight… and landing in Munich (our original destination) at 10:30 p.m. Lastly, my BIGGEST COMPLAINT is that we were told that we’d receive a $500 euro compensation on the card that they supposedly scanned in front of me… which NEVER posted. If I can avoid it, I will never fly Air Dolomiti again. *Air StoleMyTimeAndMoney* *AirWeDontCare* *AirYouDontHaveAChoiceSoYouGetWhatYouGet*

It was a short flight so all amenities were appropriate for the length of the flight.

It was about what I expected for a short haul. We were given a biscuit and water. But the people were very committed to service!!! Pilots were top notch 👌

Pessimo. In ritardo e la richiesta di assistenza per le due signore ottantenni non è stata onorata a Milano, malgrado fosse stata onorata a Monaco. Pessimo e inaffidabile

On board service was very good. Airport service in Frankfurt was chaotic.

The Verona airport is 70 years behind the times. Boarding takes forever. First, you line up at the gate, then you go outside and wait at a barrier, after a long while a bus comes and boarding it is random, then you arrive at the plane and climb quite a few steps to board, again in no particular order.

You lost my luggage. You delayed my flight 1 hour. We didn't arrive in time and missed events we scheduled because we had to sit in the airport for 2 hours to file a claim

very bad The bus does not have AC and the windows do not open either. Airplane seats are very hard, very uncomfortable.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

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

Take off was great but landing is always with a bump.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

What we can expect? Soon we will have to travel standing on the hallway. Let me be fair, I had worse experiences with Ryanair.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Everything was good. But from Frankfurt to Seattle in airplane entertainment system didn't work good.

Flight was cancelled due to maintenance issues. It was a nightmare to get an alternate flight back home.

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.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

I ordered Hindu meal and expecting a vegetarian food. Instead I got Chicken. Also entertainment system was so bad and slow I was never able to use it

I liked crew, always smiling and provided the best services.

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.

Layover time was not sufficient as the gate was too far, I had to literally run and was out of my breath. This was main drawback. The crew was wonderful and so is their service. I loved interacting with them.

They didn’t have my special meal I requested. It seemed like they just put a sticker on a veg meal for me. I had a little bit of it but it didn’t taste good and I got sick from eating it by the time I boarded my Frankfurt to NY flight

What could have been better was holding the flight when our ORD to FRA flight was a bit late. We sat at FRA for 7 hours. It takes time to go through passport control and to get to a gate at that very large airport. We went as fast possible to our gate but were too late. Cityline is a good provider other wise.

Economy seats were good and spacious. Much better than virgin by a mile.

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

The flight was canceled and airlines did nothing to accommodate the passengers. After few hours they booked me randomly on a flight that had long layover and didn’t provide any compensation or effort to help. The crew was rude, no representation on the airport. Everything needs to be on call and agents there had no knowledge or control. For everything, they were like we can’t do it and you need to file a claim later. That was not helpful at all and will not make my travel experience any easier. Very disappointed in their service.

Great plane and flight attendants. The person next to me had a DISGUSTING smelling mouth and breath, so that was nasty to deal with the whole flight. Brush your teeth, people! Condor was amazing, though :-)

It would be nice to have a cleaner facility, it was hard to access it. It was always full of people working in that space. The covers and especially the matt of bad quality and old. Many times reused. I would not use it. Food: the bread rolls were old, and food had strange choices. Chicken was terrible.

There was some nice staff when I entered and left, but the thrre flight attendants who served us were very brusque and rude. I have celiac and when I checked in, I tried to find the option to make sure my meals (stick on a 10+ hour flight after a 3 hour flight and short layover) were gluten free because I didn’t have time to get anything. Couldn’t find the selection for it, and every part of the meal and purchase options were gluten, so I didn’t get to eat. During check in the allergies section should be easy to identify and check so this doesn’t happen. Having more options for gluten free at this time should be easy.

Internet was advertised in-flight but not accessible. The foot rest in premium economy was stuck. For both nobody I asked was able to provide an answer/solution. However, this will not stop me from booking premium economy again, which I upgraded from my initial economy I had booked for my outbound flight YYZ to FRA.

Great flight, nice options for food and beverages. Fairly comfortable seats for a large person

Business class: or fist class: Seating absolutely terrible, same seats as everyone else , no space, we could not fit our knees in. I was sitting sideways since nobody else booked this business class. I wish we would have an option to select a business class for the main journey between USA and Europe, but regular class for the short flights in Europe.

The seating was exactly same as the rest of the plane. We had no space for our knees. In fact it was the tightest spacing of the seats I ever flew with, on a very old plane. (and we flew all over Asia and Europe) The same chairs. We were the only passengers in business or first class. Obviously funny.... The only difference was, we got a sendwich and we were offered a drink. Rest of the plane got a bottle of water.

The crew was great. Good etc was unacceptable for an overseas flight. Wine with a meal should be complimentary. Seat comfort /space horrible and I am 5‘3“ with heels on. Short haul probably ok but not on long haul flights

It was extremely difficult to upgrade my partners flight over the Internet from economy to economy, plus. Then it said clearly the checked luggage can be 32 kg. At the check-in counter in Hamburg, we had to pay 100 Euros ( $122.17) for the only 31kg peace checked luggage. We were told because the change was made less than 24 hours before the flight , the luggage weight would not be upgraded. Then they offered me that for €90 I can upgrade at the counter from economy to economy, plus so we can sit together on the flight from Frankfurt to San Francisco. I happily agreed and was charged. €99.($120.95), which I noticed too late. Especially about the Euro 100 up charge I feel upset and it’s a unfair way of doing business!
