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.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

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.

You deleted my connection ticket home and I am stuck in Seattle!!!!!!!!!!!

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.

It could not have been cancelled and the rebooking pro could have been smooth, not requiring me to be on hold and standing at check-in counter at Air Canada (not AC fault) for a total of 3 hours. Ridiculous.

Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

I upgraded to the business class cabin. It was the poorest business class I have ever experienced. No access to any business lounge in Tampa airport. Seats are not comfortable. I had a window seat and had to step/crawl over the next seat. Food was mediocre and service below average for business class. Bathroom location was ridiculous. No place to wait. I cannot believe I paid this kind of money and will never fly Lufthansa Discover again. They really should reimburse me somehow.

I liked the professional service that began with the information and continued with boarding and the service on board. I recommend you to use the late-night checkin the day before your flight. It made traveling so much better and more pleasant.

Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.

My flight was cancelled on April 15th due to Lufthansa strike. You basically lost customer since it was important for me to reach Poznan due to my friend’s terminal illness. I rebooked my flight with KLM and will travel with this airline in the future.

Was terri le experience with gate lufthansa personal at Frakfurt.

No problems except for a completely full flight. But we were add one because of a previous delayed flight.

The map feature on the display at the seat had challenges. The biggest issue was the flight had no WIFI. Most of the smaller planes now have free WIFI. American Airlines on the flight over had WIFI you could purchase. With 8-10 hours on a single flight, the ability to do work via WIFI is essential!!

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

Cramped seating but standard in all smaller aircrafts today no matter what airlines. Crew very helpful, friendly & attentive so makes up for that.

Wonderful business class flight in a lovely new plane with an excellent crew

OK, except for a cabin attendant's lack of attention.

efficient. on time. cabin crew were very professional and very nice to deal with. would definately fly BA again.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

I flew premium economy. My only complaint is the size of the bathroom. I am 6’2 I. Tried to rush my teeth in there and ended up getting toothpaste and water in my pants. And the only way to do it was by sitting on the toilet

My flight was delayed twice. It finally left 24 hours later. In addition there were conflicting messages between kayak and condor that made the experience worse.

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.
