Pros: "Top notch service and experience. Up there with EVA Air as the best I’ve ever seen."
Cons: "Baggage delivery took very long in Hong Kong. Bags were coming off 35 minutes after the first bag came off."
Cons: "Extremely bad service at the ticket counter. Really disappointed, really disappointed"
Pros: "crews were nice"
Cons: "Very crowded flight. Fully book. Super busy bathroom. Food was bad"
Pros: "Liked the plug/outlet availablity and the movies."
Cons: "Did not get up to date info on the final destination of bags. Food inedible, climbed from tarmac up the stairs into the plane, seats super uncomfortable, not enough customer service from flight attendants"
Pros: "The entertainment was good."
Cons: "Once the crew got the meals out of the way you didn't see them (at least in our section). You could go to the galley for water or a snack etc. Most airlines I've been on seem to bring drinks, etc to seats every once in a while."
Pros: "Premium Economy did not meet our expectation compared to even US airlines."
Cons: "Crew Service was not very good."
Cons: "The crew should be friendlier while they deliver their service."
Cons: "The television got black out 6 hours before landing..dont have a choice but yo sleep."
Pros: "Crew is very good and efficient, generally very friendly and helpful. Seats are fairly spacious and comfortable. The flight was only slightly delayed. Food and drinks are quite readily available. Meal quality is nothing amazing, but it's definitely not bad."
Pros: "Delayed. Late notification of delay. No text notification of delay."

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.

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"
Pros: "I didn’t like anything"
Cons: "The female FA gave me an attitude when I asked about moving to a window seat"

No priority boarding - all passengers used the business class lane

The "new" configuration Club class provides a fantastic experience - a private pod, with great design and plenty of room to spread out. In addition, the cabin service was beyond excellent, and the food was great. Thank you for this sector, BA - it was worth every penny.

Pros: "It was absolutely on time. Great!"
Cons: "The meal is always too spicy and for more south Asian style. I prefer more European meal."
Cons: "The plane was older and the screen was very small."
Pros: "Crew good, food okish."
Cons: "Entertainment system below average. Disembarkment was poorly handled and resulted in big delays."
Cons: "The cabin lights were left on too long for a red eye. Cramped quarters - but that is true of every airline now. We did receive a blanket and pilllow, which was nice. Did not have dinner so can’t comment. Croissant with cream cheese prior to landing was OK Nice smooth flight.Nice pleasant crew"
Pros: "The plane ride was fine. No food/drink for such a short flight, but I didn't expect it and didn't need it."
Cons: "It was slightly delayed taking off."
Pros: "No delay, nice staff, had to check in handluggage because of small airplane it worked out perfectly."
Pros: "It was cool in the plane on a hot day."
Cons: "Nothing to report, all was normal. The safety video is awful."
Pros: "Nothing"
Cons: "Entertainment and food were terrible. Plane was filthy and ancient. Crew was inattentive and we were treated poorly for bringing a child’s seat on the plane. It was hot the entire 9 hour flight. I will pay extra not to fly BA again."

Bohužel zpoždění let o více než 6 hod, způsobil, že jsme nestihli další let.

Pros: "The crew was very friendly and helpful."
Cons: "The seats were incredibly cramped - felt like the seat back in front of me was right in my face!"
Cons: "We were impressed with this airline. Service was prompt, airplane was clean, and staff was friendly."
Cons: "Seats are really small and stick together, super uncomfortable for more than 2h"
Cons: "We were waiting in the bus for a very long time"
Cons: "There was a half hour delay, but they they did their utmost to redress this, and we landed just 15 behind schedule. A lovely, cheerful and friendly crew and a very pleasant pilot who clearly understands the importance of good communication. THANK YOU."
Cons: "Mediocre, flight delayed toldto go to gate, Checked at gate after 1hr returned to departures the back to gate checked again, problem with seatbelt had to ask multiple times for Help. Not sorted went through flight unfastened with buckle issue, flight attendant attitude very poor."
Pros: "Nothing"
Cons: "The plane was grounded they got another plane bussed to it, standing on the staircase in the pouring rain, it was cold all the way"
Pros: "The fact that the flight was cheap and somewhat on time"
Cons: "We had to walk for a very long distance to get to the gate for boarding and has to pay base on different kg"
Pros: "Nothing"
Cons: "Check in was dreadful. Staff was not helpful. We were running late due to a connection and the employee told us to wait in line bc there was plenty of time. 15 minutes later and 15 minutes before boarding I went to front again where another woman said yes you need to check bags. Your site is not clear on baggage but that is pricey and should be stated more clearly. The range you state is nonsense. They charge the highest rate listed. There is no range. We boarded a bus to the plane which was also dreadful. We were in very last row. The only positive was that the flight was short!"

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.

Pros: "Flight Price"
Cons: "Not charging £45 for ski baggage when an oversize Check in Bag bag for same weight is £20"
Pros: "It took off and landed"
Cons: "Ryanair is always the worst flight, so many corners cut"
Pros: "Quick and efficient staff."
Cons: "Whole. Families split up , inc young children, one group of ten spread all round the plan. Just two of us me row 27 better half row 8 ! Only Jet 2 do this too to punish you for not paying to sit together."
Cons: "It was Delayed with out any notice. Ryan air is shocking"
Pros: "I like the staff - they were kind and helpful"
Cons: "I didn’t like how you had to pay for food and there was not a comfortable position in the seats"
Pros: "We arrived safely"
Cons: "Said on time until we arrived at airport gate- then said delay with no reason given and no one to speak to. Estimated time kept getting pushed back. If had known if long delay would have stayed in Santander and enjoyed day. Poor customer service and frustrating delays."
Pros: "Nothing to like, the flight was delayed over 5 hours."
Cons: "No communication as to what our options were, stuck at the airport for 7+ hours while on holiday. Absolutely horrendous. Then finally after all this time, seats don't move a centimeter and they are extremely tight with minimal spacing between rows."
Pros: "Great trip, right on time, plane was clean, colors are a little weird, guessing some one is a Michigan football fan"
Cons: "Flight cancelled and had to spend 4X to book another comparable flight."
