Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The boarding experience was as expected and went well. The plane's economy seating plan is not designed for a positive customer experience but rather for company profit. When the passenger in front of me reclined, the distance from the screen to my face was the span of my hand (thumb tip to pinky fingertip). There is no such thing as personal space in this setting. This results in the domino effect, for when I recline the person in back of me reclines and so it goes. This is not to say that reclining is the answer as the experience is not increased, but simply managed.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Very comfortable flights. Not so many new releases in terms of films.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

Average flight for which I paid too much for on a last minute purchase.

Would have liked working outlets on the flight. The first meal was very bleh, the second meal was a lot better so overall okay meals

In flight entertainment system including wifi were down and passengers got tortured for the 16 hours flight without any of these. Food was spoiled as well for the first meal provided but second meal was Ok. Overall a horrible experience which was not at all expected for such a long haul flight which was expected to be THE most memorable part of my planned trip for family.

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

Pros: "The crew was amazing and took measures to make the flight Covid safe"
Cons: "The food was not the best and Twistees weren't available. Also the seats felt narrow"

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

Staff had been really impolite at the boarding area and for both ways charged high extra fees without a reason. For the check-in luggage which was measured 3.5 kg and was confirmed by the stuff to cost 40 € , 60 Euros had been purchased from our credit card. When confronted staff did call us both liars and claimed to never have announced anything. Flight back , when not wanting to press a backpack in a measuring metal instead of hand measuring , staff got angry that one did not follow her order, which was than escalated by the team. Although carrying a baby anyways staff did not offer any help in the unreasonable process and than charged again extra money. Cabine crew has been friendly but this experience LL lead to not booking easy jet at all in the future. Check in process in Edinburgh anyways chaotic,to the family check-in and disabled check-in everybody else was guided for check in process, so people just getting in between each other, not possible to monitor your own stuff.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

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

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

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.

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

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.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.
