Read more about Cathay Pacific
Cons: "I wish there was air conditioning. It was very warm ok the plane."
Pros: "Everything and everyone are Good and Nice ."
Cons: "For a long flight ( 16 hours or more ) , if someday I can afford First Class , that’s make my life . Thanks"
Cons: "The television got black out 6 hours before landing..dont have a choice but yo sleep."
Pros: "Innovative seating arrangements in business. Service was good."
Cons: "Comfort of seats and laying position are ok, a bit hard for 15 hours."
Pros: "They serve Baileys. I had a treble and then slept for 8 hours."
Cons: "I was served by the sassiest member of cabin crew. I think he thinks he’s doing us a favour by giving us such luxuries as water and food"
Pros: "Good entertainment choices. Preferred check thru TSA. No one seating next to me."
Cons: "I don't think I will use Kayak again. You farmed out my booking to Voyama which spelled my name wrong. They refused to reissue my ticket with the correct spelling so I had to sweat out getting on board the airlines and now I have to sweat it out today because they again refused to reissue the ticket"
Pros: "seats that i selected was change when we enter the boarding gate without informing us"
Pros: "Customer service is excellent as usual. The plane is very well outfitted and modern. You can generally trust the Cathay standard. The pilots are good, and even though departure may have been delayed, we arrived ahead of schedule."
Cons: "I didn't prefer the premium economy section. Uncomfortable. I'd rather pay the fare for a cheaper economy seat, that is equally uncomfortable. It's terrible to start charging people for small, petty things like choosing one's seat."
Pros: "The overall boarding arrangement is smooth. Crews are friendly."
Cons: "The further delay made us arriving Hong Kong at midnight. We reach home at 1.30am."
Pros: "On time departure and arrival, in flight service and comfort."
Cons: "Entertainment system seems old, latest movies are not there and the flight maps interface looks like as of it is from the 2000s."

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.

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

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.

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: "I didn’t like anything"
Cons: "The female FA gave me an attitude when I asked about moving to a window seat"
Cons: "Both times into Rome we had to wait on the tarmac for stairs. Either get more stairs or book fewer flights. The planes get hot in July while you wait endlessly on stairs."
Cons: "The flight itself was absolutely fine but we are very unhappy with the what lastminute.com did regarding our tickets. (As you will see when you look at the notes for our case). We shall be seeking legal assistance upon the return from our holiday & contacting you/lastminute.com for compensation."
Pros: "fabulous flight and crew"
Cons: "Perfect take off perfect landing so smooth nothing more can be better - Thank you!"
Cons: "Check in was a mess. I paid for a seat but was given a seat at the back. Fortunately, I had the print out and insisted to Ck it."

First leg of the itinerary from RDU to JFK was brought forward and was not communicated on time. Flight was missed and we had to pay extra to get to JFK. At JFK the British Airways kiosk initially refused to let us get on the remainder of the flight to LHR and ABV and Kayak couldn’tbe reached by phone. Poor poor service. Bad communication.

We had the best flight attendant - so funny and helpful. Such a change from the usual .

The deplane in London needs a lot of work, long wait to get on the bus and the ride from the aircraft to the main terminal way to long .

Pros: "Staff was great. Good experience for our first overseas flight"
Pros: "Everything went smoothly and I was very pleased with flight experience from beginning to end"
Pros: "Crew very pleasant, professional and friendly."
Cons: "Tired and dated cabin; seats extremely uncomfortable causing severe back pain. In flight entertainment very old fashioned with small low resolution screens."
Pros: "Stress free trip - fine all round"
Cons: "Auto check in wouldn’t recognise passport (YET AGAIN- and not only mine)! Was seated to rear of aircraft and coffee trolly didn’t get to me before ‘seatbelts fastened for landing’ announcement.."
Pros: "The crew was professional. Plenty of space to store my carry on bag overhead. I also like the safety video at the beginning, featuring actors and comedians."
Cons: "I have no complaints about this flight."
Cons: "No in-flight entertainment available. Why are some airlines still charging for snacks?!?"
Pros: "Crew was great. Accommodating and welcoming."
Cons: "Food quality could have been better. Snack was very poor before landing."
Pros: "Crew was very nice and the plane was comfortable"
Cons: "There were no outlets nor entertainment, and boarding was a little long"
Cons: "on easy jet, if you do it check in online 34 hours before the flight you get bumped to standby. This is not made clear in any emails or confirmations. Despite purchasing a ticket in advance I almost missed my flight because I checked in at the airport."
Pros: "Cheap fare for this short flight. New planes, seats while thin still offer acceptable comfort."
Cons: "Very long walk to the farthest end of terminal for gate and have to walk up the stairs to board plane on the tarmac. Not a single human being to help check in or tag luggage for drop off. Everything’s self service. The check in/luggage drop off counter difficult to find."
Pros: "The crew was excellent, the flight was comfortable however the boarding process was a bit disorganized but I’m pretty sure that was an airport issue"
Pros: "flight left close enough to onetime to arrive onetime, flight was smooth"
Pros: "1hour 30 minutes late. No acknowledgment of this or the knock on impact"
Cons: "Compensation"
Cons: "Terrible service! Had to pay 50 pounds to check in bags, but didn’t get checked."
Pros: "Flight was smooth and on time"
Cons: "I don't like the boarding procedure and I have problems with the legroom between seats. But then it's a no frills airline and the price was attractive."
Pros: "Hard to understand some of the crew announcements due to speaking way too fast"
Cons: "Both flights there and back we're delayed in total about 4hours and when you're away for a wkend that's a long time!! I've flown with other companies over the last few years and times have been spot on!"

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.

Pros: "Quick boarding."
Cons: "The seats are just not comfortable in the slightest. There is no room. No where to put your legs."
Cons: "The area we were put in prior to boarding was just a continuous weaving queue and was quite crowded and stuffy"
Cons: "Never made the flight due to the previous flight being very late Eventhou that Norwegian sir that I will never use again lied about delay time , they said 50 min and ended up being 3 hours"
Pros: "Boarding was fine and plenty on room for our bags as we had paid priority"
Cons: "The hard and cramped seats with very short legroom"
Pros: "That the place reached safetly to its destination"
Cons: "Rome Line to checkin started at the entrance of the airport with no Ground staff attention or clear line marked people were fighting and cutting each other . Check in process approved our luggage for hand cary as we paid for it in advance. In the gate they suddenly decided the luggage was 1 cm larger then agreed, refused to bring a measurement tape and charged us 50 Euro in addition to send the luggae in the plane rather than hand carry. Need less to say that in the flight to Rome our luggage was approved for hand carry so clearly Rome staff were into making money.. Planes were late to take off and 1 hour late to land (that from a total of a 3 hour flight ) although not announced . In summary ground staff experience was awaful and made us decide to not fly with Ryanair air again"
Pros: "The flight was smooth and calm. The crew was very professional."
Cons: "I did not know in advance about the checked baggage charge. The web site was not clear in this regard. The cost to pay this charge at the Rome Airport was double the price of doing it in advance. This also created a lot of unnecessary stress. We barely made the connection even though we had two and a half hours between arriving in Rome and the departure of the Ryanair flight. Also, there was a delay after boarding of almost one hour."
Pros: "crew very good"
Cons: "2 hour delay and no information, even changed boarding gate and did not inform passengers who was already waiting."
Pros: "The crew was very warm and the seats had great room."
Cons: "There was no entertainment."
Pros: "Nothing"
Cons: "Dirty seats, tables and floor. Both times we checked in and because we didn't pay for early check in we all got separated despite there being room to all sit together or at least in pairs. Had to pay to move to sit together. It costs £80 to bring a suitcase for the hold, however if you don't pay for priority boarding your handluggage gets placed in the hold anyway despite there being more than enough space in overhead lockers. If I had known how much it would be to pay for the 'extras' which area really basic requirements, I would not have booked with Ryanair. Next time I'll be going with another company who actually provide a basic service"
