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.

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

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

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

Delayed getting out for no good reason. Tight connect lead to a missing bag in Hamburg. Waited two hours at the airport to get the bag from the next flight.

Crew could have been more helpful in helping to find location to store luggage in overhead bins in order to expedite seating. Seating was cramped and uncomfortable.. Other than that it was a standard flight.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Had a delayed flight that caused me to miss all of my flights. Supposedly I was rebooked. When I got to my next connecting flight there was no ticket for me. I spent hours working with an agent. And they still couldn’t get it right. I will arrive home more that 24 hours later than my original schedule. Totally inept and frustrating experience.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

Very good, i got two seats for myself, and was comfortable with the blanket i got

Not to bad but it was hard changing my seat

Economy Priority seats are extremely uncomfortable. There is no way to escape the boxed in feeling, particularely because the distance between to rows are too short, the hard edge of the front row is keeping legs confined. There is no elevated place to put your feet. I am of average, European size.

Terrible. Both flights were significantly delayed, no luggage, made me check my small bag when many, many others had much larger carry-ons, not even a bottle of water . . . I will not fly Discover Airlines again.

Club Europe is always lovely. I really enjoy everything about it. One thing that has changed in recent years though, is the swap to Prosecco from Champagne in the lounges. This is really disappointing. I really don’t like Prosecco, and always looked forward to a lovely glass of champagne in the lounge. Is it possible to change back? It does make the whole experience a little more of a luxury experience.

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

You will pay for everything and feels like the airplane is old

The luggage problem I previously mentioned was actually this flight

The flight was delayed due to snow in Frankfurt. There wasn't much information from BA or the airport, but Kayak was great and kept me informed of the delay and gate changes.

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

Upgraded to premium economy at the gate. Well worth it!

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
