Pre-boarding seemed tom happen at the same time as Business Class - I thought the idea was to allow people who needed extra time to board without interference from other boarding types, but I guess that's how they do it at LAX.

Pre-boarding seemed tom happen at the same time as Business Class - I thought the idea was to allow people who needed extra time to board without interference from other boarding types, but I guess that's how they do it at LAX.

Austrian Airlines was fine - it was the Munich airport’s system for boarding with new EES requirements. Instructions were confusing, waiting lines were LONG and many people had to run to catch their flights.

It was very bad. We were delayed for 2.5 hours. After 9 hours traveling from Vienna to Washington my airplane was not on time. It was very frustrating

1) have phone numbers where we can call... a human... not this bot stuff... 2) the austrian airlines crew directs us to the airport lost and found for left behind objects, then the airport lost and found directs us back to them. Listen y'all, if you can't get this straight, what are you thinking expecting us to? Cheap, unprofessional, looks like a airline on the way to going under. If you can't afford well-trained staff... well... ask not for whom be bell tolls... it tolls for you.

The good: we liked fast boarding, the departure and arrival on-time. The not-so-good: The crew should learn from their sister-company Swiss with whom we took the flight to the US. Austrian onboard personnel need to smile more and provide a better service. Food was okay, there was the usual issue with “no more chicken” by the time they reach row X 😕. We did not understand why the crew collected trash so randomly and inadequately. We missed the free internet for messaging which was privided by Swiss as well. Hope this feedback helps.

They should be kind to the people Food is always plain pasta bread is from the fridge they don't even warm up Seat is so uncomfortable body hurts

Just overall a poor experience with little to justify the price of the ticket!

I am very satisfied for choosing that Airlines! It was my first time but the everything went smoothly! Thank you!

OK, would prefer some meat for dinner, not just pasta although was tasty. There was only one dish, no choices

From all the segments I flew it was the only one I did not get the option to choose ni seat, I did not get the quality of seat I had paid for. Crew was nice, airplane was clean, but no food, only water and a small courtesy chocolate. Everything else you had to pay for.

Had a lovely flight arrived 25 minutes early food was good staff we lovely.

Boarded and sat on plane for 3.5 hours before taking off, Updates infrequent and no refreshments offered.

I didn't have food, and there was no entertainment as it was a short haul flight, so can't comment on those, The head cabin crew member was addressing the passengers like a telesales person reeling off terms and conditions; we didn't understand a word he was saying. This is the second time this year we have flown with Ryanair, and both times we've had to carry our luggage downstairs to walk to the plane. As were both OAP's this isn't really acceptable. We have another flight booked for September to Lanzarote, so hopefully that will be better.

Smooth journey made good time. The aircraft was littered and did not look very presentable.

Flight was ok until there was a sudden juddering in the plane and a severe sudden loss of height. There were a lot of distressed passengers and not a single word was said by the pilot or crew.

We had to wait 2,5 hours in the plane before take off!!!

The flight was 1h delayed. There was a flight attendant making announcements in the cabin, but it was impossible to understand whether the information was important or not. (Although whatever she was saying, it was clearly meant to be communicated to the passengers.) From the way she spoke, it sounded like Spanish, but only thanks to catching one word out of every five or six — mumbled through her teeth — I realized she was actually speaking English. It was quite embarrassing

The table at my seat was dirty, the crew was nice, the boarding was swift. An average Ryanair experience but this time the plane was not properly cleaned between flights.

Ryanair was ok but the flight is delayed 2 hours! We dont know the reason if it was either Ryanaair or the Kos airport or Vienna Airport …

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