The crew is amazing, very attentive. They went above and beyond when we had a small spill. the food on this trip was not nearly as good as other Cathay flights. The economy seats are very comfortable, but when the person in front of yo reclines, you need to recline to see your screen or be comfortable.

Cathay Pacific helps me with the planning due to weather delays. Well planed flights.

Flight crew went above and beyond to make sure the flight was enjoyable for us!

Both my husband and I ordered the fish for dinner and we both got sick and throwing up on the plane. I don’t think the seafood was handled properly and I for sure will not order fish the next time around.

Im now late to my appointment because of delayed flight

Dinner was served at the wrong time as soon as we boarded. Most were sleeping.. there was no food service carts for hours. We had to specifically ask for water, snacks etc. for the 15 hour plus flight, there should have been 3 meals served. Instead we only got the breakfast 1 hour before landing. Will try other airlines like Qatar for future travels.

No proper procedures or announcements for boarding. Not even water was served on flight. Could not check in on line. This option was not available .

I like the paper menu with lists of food, so that I don’t need worry about to pick up the food I don’t like, because crews are busy to do food service, mostly not enough food information they can tell. Well, one of the lady was not friendly at all, I asked three times my daughter wants a cup noodle during the flight, she gave me the reason is they have half an hour for serving food three times. There are more than 200 people on the flight, it takes them more than hour and half to do food serving, think about it, how long we can get food, around two hours. I don’t like she gave a stupid reason other than to make a cup noodle right away. Unfriendly and lazy.

Flight delayed in NYC and missed Hong Kong connecting flight to Guangzhou. While being given a hotel room and a 30 dollar voucher to eat in the airport, the delay caused a few big inconveniences , a 12 hour delay should have been better compensated for.

Wanted different plane design with an additional bathroom at the back of the plane.

Our check-in was mediocre. We were told that we didnt have access to the lounge although we were in business and we were asked to remove 1kg from each of our checked luggages as they had 21 kgs and we found out that our tickets were for 20kgs checked bags. I would have expected: 1 - more clarity on the website so that I could see the difference on fares and be able to buy tickets with more checked luggage kgs allowance, and lounge access, and 2- more flexibility for business class passengers.

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.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Usual issues with flight delay. Perennial problem of travel by plane.

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

All around poor experience. Barely got on flight because it was ostensibly overbooked. Forced into checking a carryon bag with empty overhead compartments. Nickeled and dimed. Charged for coffee. Despicable.

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

Nothing! The service was excellent for accessibly challenged passengers, Used lift and all support personnel very helpful. Will fly again.

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.

Good service for a budget trip. No problems at all

When having difficulty with the online check in process, I was forced to pay a huge fee for the check in desk to assist me with getting a boarding pass. Ridiculous!

Keep track of your departure times and communicate in Airport. I could have spend an hour more in my lounge

Never have real problems...very ho prices for good the rest is all great

Very good, staff seemed to check random cabin bags for size pre boarding.

Terrible experince. The flight was delayed for 4 hours and we had to sit in the plane for 30 minutes without AC. At least they shouod have given us complimentary bottles of water but no one had to buy them.

Ryanair is always shite. Slowest boarding possible in the most uncomfortable way. It’s like they are are tad sadistic.

Flight was delayed which happens but walking 15 mins to one gate to be then told it’s now changed to one 15 mins back then other way was frustrating

East check in and security. They are always delayed though. ALWAYS!

Amazed at huge number of people who hadn’t booked cabin bags with big troller cases and rucksacks, not being stopped, what’s the point in following rules or paying more if you don't have to bother?

It was a great experience. I did find that some menu options were not available, which was a bit surprising, but over all a wonderful experience.

I wasn't able to request a special meal on the on line check in. I informed the cabin crew and they went out of their way to find foods I could eat. I am very grateful.

All went well- allow plenty of time at Heathrow, we felt like we got bused halfway to chicago when it was time to board, then had to carry baggage up steps outside. A bit of work for anyone who is less mobile or able bodied for sure.

It was a pathetic experience. Booked Hindu vegetarian meal and they served chicken. Inspite of telling them repeated times, the issue was not resolved.

I never was able to take this cancelled flight…all flights from Zagreb were cancelled at 3:30 AM of departure day 9/8!

Experience was probably the best I’ve had on BA for a long time. Only thing is A380 is old now and it needs upgrading. The en re attainment screens are very small and the touchscreen barely works.

Flight cancelled! Rebooked by circuitous routing although there were seats available on other nonstop flights.

Service of the crews were great. Food on flight was very greasy, and salty.

Sardine can herringbone layout in business class. Uncomfortable and nowhere to put your book, phone, headphones, etc. worst hard product ever, and the service and food aren’t good enough to make it worthwhile. Expensive garbage. British Airways purchased this thinking only about financials, clearly not customer experience. British Airways business class is the garbage truck of the skies. Hard pass!

Horrible. I bought a flight with British airlines from Amsterdam to Orlando via London. Less than a day they changed my flight to London so I had to fly to London city airport and then find my way to Gatwick for my connecting flight. It was very costly
