The customer service was very poor. I didn’t get any accommodations for my cancelled flight. I was without any sleep for 36 hours.

2.0 MediocreAnonymous, Apr 2024DXB - MIA
Read more about Emirates reviews

The customer service was very poor. I didn’t get any accommodations for my cancelled flight. I was without any sleep for 36 hours.

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

Service needs to improve. Air hostess do not register flyers request and we need to keep on repeating our request to them on multiple occasions

The experience was not as pleasant returning as leaving. Went through clearance twice, crew was not as customer focused.

Good but needs to improve cleanliness Coffee serve cold Needs to raise standard serving food Otherwise good

More leg room and comfortable seats at least for long flights

Very bad !! My confirmed ticket got canceled with out notifying me in hyd airport , crew didn’t help us out !! They were very rude!! They made me pay for the confirmed ticket again !! Can you please let us know how I can get the refund for the ticket I paid

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Emirates flights always nice. Service rendered by the staff is superb.I am always comfortable in Emirates flights.

I bought Business class ticket but they treated me like economic class. No lounge allowed at check inn I have to take stuff out while other passengers have more than 25 lb in bag. Because I bought tickets from other than airlines . It’s discriminations from airlines to passengers.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The staff we fantastic and seemed to work very well with each other

Business lounge in Melbourne mediocre. Look at Emirates or Qatar, Qantas! Great friendly crew. Food was good but Emirates is a level above. Business seat good. But can’t compare to Qatar. Main reason for booking Qantas is loyalty and terrific connection via Perth to LHR.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

The crew were amazing - A great job. They made me feel special and valued.

I really appreciated the fact that when I checked my bags at the Quantas counter after arriving from an international flight an hour early, the agent noticed I had a very long layover. He then found an earlier flight that allowed me to get to Cairns several hours earlier than I planned. That was amazing because I had already traveled over 20 hours and wasn’t looking forward to such a long layover. It allowed me to see my daughter and grandchildren much earlier (it had been two years since I visited last).

Qantas cancelled my flight for no good reason and rebooked me into a middle seat.

Boarding was terrible - the ground staff member Fredeya at lax was more military than customer service, have never encountered a customer service representative as rude as her. Apart from that all other staff were wonderful and the flight was good.

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

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

No bording 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

Lost luggage, 2 bags were badly damaged and one of the bags came open.

A couple of minor delays in boarding but very professional and efficient staff.

Sky priority means you get to use the KLM business Lounge.

their gluten free lactose meal is the best, I have never been satisfied with my flight meals. I definitely enjoyed my flight and the chair is very spacious for economy. I'm so glad Delta is my flight way back to NY.

The crew was great and handled our unexpected detour with proactive communication.

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.

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

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.

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

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

1.Aircraft Comfort: The aircraft type was quite small with non-reclining, cramped seats that significantly lacked comfort. 2.In-flight Entertainment: There was no provision of in-flight entertainment screens or Wi-Fi for the majority of the flight. 3.Boarding Process at New Abu Dhabi Airport: Despite the move to a new airport, which promised enhanced experiences, the use of buses instead of jet bridges did not meet expectations, causing inconvenience. 4.Gate Change Communication: A last-minute gate change was poorly communicated, resulting in a long and difficult walk.

Very very bad service very tight seats never ever flying with Etihad again

The food is good, but i am nit used to those foods so I can’t really be more detailed.

Dear Etihad Airways Customer Service, I hope this message finds you well. I am writing to express my deep disappointment with my recent flight experience on Etihad Airways, which took me from India to NYC via Abu Dhabi. My flight details are as follows: [Flight Number] on [Date]. My overall experience was marred by a series of significant issues that I believe warrant attention and improvement. These issues include: Bad Conditions of Washroom: The state of the washrooms on the flight was far from satisfactory. They were inadequately maintained and lacked the level of cleanliness one would expect during a long-haul journey. Seating Space and Comfort: The seating arrangement left much to be desired. The seats were cramped, uncomfortable, and the legroom was insufficient for such a long flight. The seats did not recline as expected, making the journey quite uncomfortable. Cabin Cleanliness: The cleanliness of the cabin, including seats and tray tables, was not up to par. The lack of cleanliness impacted the overall comfort and satisfaction of passengers. Excessive Noise: The flight was notably noisy, with disturbances and loud noises making it difficult to rest or concentrate. The noise levels were considerably disruptive. Food and Catering: The quality and variety of meals served on the flight left much to be desired. Furthermore, there were issues with accommodating dietary restrictions, which is crucial for passenger satisfaction. Hygiene and Sanitary Facilities: The condition of the restrooms was subpar, and essential hygiene supplies were not adequately provided. This falls short of expectations for a long-haul journey. Overall Experience: Regrettably, the combination of these issues significantly affected my overall experience during this long flight, making it far from the comfortable and enjoyable journey I had anticipated. I understand that maintaining high standards on long-haul flights can be challenging, but I believe it's vital to bring these concerns to your attention in the hope that they can be addressed and improved upon in the future. As a loyal Etihad Airways customer, I had higher expectations for my journey. I kindly request that you take these issues into consideration and work towards enhancing the overall passenger experience on similar routes. Your attention to these matters is greatly appreciated. Thank you for your time and understanding.

Good leg room and I picked the seat in last 24 hours. Food was tasty with 2 full meals and first one smaller. The crew as expected courteous and on their toes serving extra water and items in between.

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

They sell 1h /1h30min connection ticket that are impossible to make

Seated in business class. Bed too hard and no comforter. Way too many seats in business class for number of crew so never felt particularly looked after.

It was ok but not at a business class standard No entertainment system available which is poor for a 3+ hour journey Food was ok and service was good though

Great service and air hostesses, took care of all activities very well and smooth

The crew was great but we sat in the plane for over an hour before takeoff combined with a 4 hour delay on our previous flight caused us to miss planned scheduled meetings in Geneva.

Both flights into and out of Heathrow were delayed over two hours due to BA technical problems. Ground crew was not very friendly. However cabin crews were

Flight staff was amazing! They deserve a raise. Middle seat was very uncomfortable

Stewart's and Stewardesses were kind amd polite. Pilot communicated very well. Will definitely fly British Airways in the future.
