Airline reviews

Departure was 2.5hrs. Sat onboard for this period with very poor comunication from the flight staff. Food standards were very average compared to Emirates normal standards. Arriving into Melbourne late was a complete disaster. One of the worst airports for managing large crowds entering immigration. The smart gate and declaration process is a joke. Luggage extremely slow coming out.

Departure was 2.5hrs. Sat onboard for this period with very poor comunication from the flight staff. Food standards were very average compared to Emirates normal standards. Arriving into Melbourne late was a complete disaster. One of the worst airports for managing large crowds entering immigration. The smart gate and declaration process is a joke. Luggage extremely slow coming out.

The crew were absolutely fantastic. They actively asked if passengers wanted refills and if they were comfortable. I was extremely impressed.

Emirates A380s are always wonderful to fly on. Their crews, food and service are always excellent. They are typically on time and the only thing I would change (maybe newer or upgraded aircraft have this) is bluetooth so I can pair my noise cancelling headphones without a cable.

Wonderful Premium Economy experience. Felt as good as Business Class for food and entertainment. Comfortable sleeping too

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

Vegetarian food was unpalatable! Definitely need to look into this. The crew were prompt and helpful and the flight as one would want was uneventful. It was a comfortable flight, with new aircraft more legroom and seating space. Would recommend travel with Emirates to others as well.

Always my favourite airline. On time, lovely staff, clean comfortable seats. Well done

I enjoyed the live television programming for entertainment, and honestly everything was acceptable. It’s just that I choose emirates, because they have always been so much better in so many ways – food choices, service, accessibility, friendliness of the staff. None of those things were poor, but they have definitely slid from their position of excellence. One example would be that after the dinner meal was served, the flight attendants huddled in the back galley with the curtains closed (by the way, that’s where snacks and drinks are), and you have to interrupt them to go back there to either ask for something or to get a snack. While they do not respond in an unfriendly way, you are led to believe that you are interrupting them by coming to get a snack or making a request. Even something like, “ Yes, how many I help you?” would be a great improvement.

Premium economy on Emirate A380 is simply the best non-business class product. In fact its probably better than many business class if the seat isnt lying flat. The food and service is close to perfect!

Poor. Flight was delayed by 50 mins. Poor quality aircraft. Aged, few parts broken. Bad plane.

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

I think it is much better than the flight I flew from Sydney to Tokyo.

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

We had a medical emergency, needing to get to an emergency room upon landing at LAX. I let the back flight attendants know the situation. One, David, contacted the pilot, who made arrangements for EMT's to be there when we got off the plane. They went above and beyond for us. We didn't have to go through customs, as a customs person came to us and checked us right at the exit of the jet way. Another wonderful woman, a United employee at LAX, perhaps a customer service liaison, took care of our luggage situation, as we weren't going to make our connection to Bozeman. When we came back to LAX to see when we could get a flight to Bozeman, the personnel are very accommodating and booked us on the next flight out, and assigned good seats. It was a horrible flight, physically, from Sydney to LAX, , but the professionalism of all involved was excellent! We are very grateful fir the way they all stepped in and helped during a very unpleasant medical situation. Thank you!!

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Movie options were quite limited in terms of the new releases The boarding in Goa was was too cumbersome with multiple security checks and passport checks. Seems like we are trying to create redundant processes with no valuable gains. A lot of waste in the system and it’s really frustrating for us customers.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Excellent will be flying again in May with Qatar. to Botswana.

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Very tight seating. Crew seemed too dis interested and too slow to remove main meal trays.

The first and longest leg, Washington to Doha, was in a 777 that was very loud. This was an older aircraft. The second leg, Doha to Delhi, was in a much newer aircraft, an A350 and was very substantially quieter. The service was good on both, though as always, the crew leaves you trapped with your meal tray for a really long time. Additionally, the flight crew seemed inordinately afraid of turbulence, keeping the seat belt sign on for long stretches when there was barely noticeable turbulence.

Seats were very comfortable and the staff too was very friendly.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

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

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping

Crew is polite, but artificially polite. You can see and feel it. Food could be better.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

2 parts to the journey. First leg covered in a newer plane with decent staff + POOR FOOD QUALITY but the second half didn’t leave a positive impression at all as the plane itself was an older built and the crew didn’t serve properly. Language is an issue with China Eastern flights as always, but unmotivated crew just makes it even bad.

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

We were cutting it close on our connecting flight and notified all staff at departing gate and flight attendants. From the start, we were told to check in with the international transfer desk by everyone, except for one lady who wanted to argue the time difference that was already taken into account. We also asked if we could try to exit the plane first (our family of 4 and 8 others on the same connecting flight). They just told us to check in with international transfers. We landed and had very little time to make our next flight. We were not offered any assistance or communication to the receiving gate. We ran all the way to the international transfers gate only to be turned away. I think we could have made it if we were allowed to exit and a call was made to other check in counter. After that we spent 6 grueling hours with our kids trying to rebook a flight. No food of any type of compensation was offered besides a dirty hotel room. The ladies with China Eastern at the Shanghai International counter were rude an unhelpful. We were directed to 3 different counters and waited before they said they forgot about a hotel. It was a long, miserable day. I believe this could have all been avoided.

You’re in the three parts of my life, the China Eastern air crew remembered and wish me happy birthday. I was given pastries on two different occasions and a complementary drink. The stew is wish me happy birthday and gave me a birthday card. Everything was first class. Thank you.

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

2 hours delay on the 1st plane out of the day!!!!!
