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

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.

Cons: "I had many problems to do the checkin with my little dog, Lufthansa didn't help me. I can't to flight and when I tried rebooking the flight, I need to buy a new ticket because though I was in the checkin on Zurique airport talking with Lufthansa staff, they considered that a NOSHOW ocurred."
Cons: "Air Dolomiti cancelled our flight to Frankfurt. Had to fly from Milan. Very disappointed! Cost us extra $$$!"
Cons: "Could have been on time so the next flight wasn’t missed"

Really bad airline, they treat you like you would be treated on a budget airline.

The smoothest boarding, courteous and experienced attendants, comfort and food/drinks I have ever experienced flying Economy on any airline! It made a 12 hour flight no burden at all - Thankyou Lufthansa!

Everything great. Just didn’t get my checked bag. Never left Berlin

This airline is the cheapest airline I ever seen I had to pay for my seat and it wasn't even same isle with my husband They charge for everything very rude crew All they think is to sell Who care about customer service just sell you tea coffee water etc.

Everything could be better. The plain was in Orlando for 3 hours prior to boarding. After boarding all the passengers they found out that plane has a mechanical problem. After an hour the problem was solved, the pilot comes on and states, (We have to go back to the gate and take on more fuel!) Are you kidding me???? Who they have for pilots, Boy scouts?? I barely made my connecting flight to Vienna, but my suitcase did not. I'm still waiting for it, in Gyor, Hungary. Am I having fun yet?? Other passenger were in the same binned. I travelled all over the world both for business and pleasure with all types of airlines. By far of all the carriers I travelled with, Discover is the worst. I'm contemplating to bight the bullet and go back to the US with a different carrier. For International flights, the seats are made for little people. The person in front of me had his seat reclined the whole way, I felt like he was sitting in my lap. For closing, I would not let my dog travel with Discover, yet alone recommend it to an other person. Does it sound like I'm frustrated, Think about having to travel back to the US with them. I'm sure I'll not hear back from you, because nobody wants to hear about bad news, but with all the hype Discover puts out there about their services, nothing could be further from the truth.

Only problem we experienced was not anything to do with Lufthansa. When changing planes in Frankfurt we spent over an hour on passport control line. Lufthansa did a marvelous job on everything from keeping me informed via texts, to terrific cabin crew.

The business class seat is the same as economy with 2 people instead of 3. That's not how it should be.

Bordón could be bettet if the company say before boarding the order of the different groups.

Checked in is easy and it was a smooth flight from LAX to Munich

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

Very good, everything went straight forward, boarding, during the flight, landing and all on time Well done

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Flights were on time. The crew was efficient and friendly.

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

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

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

Flight bumpy but good. 1 hr 20 mins for luggage not so good.

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.
