Airline reviews

The Premium economy class is not the same as some other airlines because there are no economy seats on these planes. Basically you’re getting an economy seat that’s a little wider. The seats are not that much more comfortable. The service and food experience is similar to economy class on other Asian airlines. There aren’t enough toilets for the entire plane therefore we are forced to share the business class toilets that are closed off with curtains.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

Flight never took off. Boarded after multiple 30 minutes interval delays for hours.. then after an hour onboard, captain announce cancellation and back on the bus to the terminal with no information and everyone to fend for self.. Emirates did absolutely nothing to communicate either electronically or announcement. It’s unprecedented I know with the flood but lack of communication creates anxiety and extra pain for staff. Emirates should do better.. no supervisors monitoring floor and passengers abusing them which isn’t right but should Have had supervisors monitoring

Worst ever. No assistance and communication from Emirates crew. No visibility of when the flight is flying. Couldn’t understand if we can go to lounge to take rest. Emirates system at a certain point said flight is not operating and suggested to take the next flight and in few minutes it suddenly opened the gate for boarding. unsupportive and rude crew. Worst experience ever. Flight was delayed by 5 hours so need the compensation for that.

The customers before boarding the plane from Dubai was HORRENDOUS. The entire Emirates staff had a stick up their bum. The guy at the check in booth was rude. I don’t understand.

Flight from Dubai to Zagreb very bad cabin crew. Bad food

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

Newly reconfigured 380 I assume. Has a new ife with usb c ports and Bluetooth connections

Check-in counter at the airport took more than an hour of standing in queue with online checkin. And after entering the gate the flight delayed more than 30 mins.

Me and 2 other rows were forgotten during food service. We waited over an hour before they finally served our food. Then only had what was left. They did apologize. Also, they locked the bathroom due to turbulence and my 4 year old had to pee himself because they wouldn’t unlock it for him.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

No bording was given for next trip on same carrier, food was very moderate.

No birding was given for next trip on same carrier, food was very moderate.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

The line at boarding was not well organized and managed

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

Crew were very polite and quicker in service. Excellent cooling, comfortable seats and tasty food served

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

Etihad broke my suitcase Also over charged me for luggage

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Crew member took too long time to take back leftover food plates from passenger seats. Food was nice.Easy excellent checking.Guy at checking counter was really kind and helpful.Made our checking very quickly. Leftover food should be taken back ASAP. Because in economy class passanger have narrow space . In the long journey like this, passanger have difficulties to sit with the plates.overall experience was good.

The boarding to Gatwick was a breeze but the boarding from Gatwick was a nightmare. The onboard service to Gatwick had a lot to be desired but the onboard sevice from Gatwick was amazing ! Very nice,friendly and funny ! Would I recommend BA to anyone.? ! Yes I would!

Flight boarded and took off late for unknown reasons. Crew insisted we check our hand luggage due to full flight, which it was not even close to full. Then had to wait almost an hour a and a half for the hand luggage to come onto the luggage belt since it was loaded last. This came after many hours of traveling pregnant with my 6 year old daughter. Really didn’t appreciate the unnecessary delays. What the hell?

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

They cancelled our flight the morning of departure at 4:30am.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

The layover time was barely 1.30 hrs and the security clearance sucks. I almost missed my flight but for the help of a manger. She held the flight for me. My baggage did not arrive. The entertainment did not work, I had to switch my seat 3 times for different issues. The travel was not fun
