Airline reviews

The food on this flight was just terrible. I have a wheat allergy so when booking I ask for gluten free options. The food given was inedible. The bread rolls were rock hard. Once board I was given one and the only thing I could do was eat the chicken slice and piece of tomato on it. Also given was 4 small cubes of fruit, 2 watermelon and 2 pineapple and a bottle of water. My husband had a regular meal and found his very average. Then the evening meal was also disappointing! Some dried out fish with spinach and 3 sticks of dry white sweet potato. No sauce …. 😳 again, the same fruit and water. The passengers had to wait a long time for the dinner food to be served. My husband just wanted to eat and go to sleep so he was a bit annoyed about that. We got off the plane and I was feeling quite hangry. Not enough food or a good eating experience. Emirates used to be a flight we looked forward to… now we are considering looking at other companies for the future.

Emirates used to be a flight we looked forward to… now we are considering looking at other companies for the future.

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.

It was good no problems made it on time for the next flight overseas!

Not good. Expected a lot more as far as excellence.

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

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

Food and Service inside the flight. Airport service from Qatar is not good mainly because of lack of coordination and not used of seeing so many ppl commuting

Better service is needed. I booked for Qatar but I was switched to American way after I bought my tickets.

If you want to make money pls charge it in the ticket, Chennai check in crew simply forcing travelers make payment for unnecessary. Second, Chennai crew not even listening travelers request. Poor service and not sure you will improve with my feedback.

I encountered challenges with the boarding staff during the boarding pass issuance process, leading to disagreements. Despite my agent's information that carrying a small cabin bag along with a separate bag containing my laptop and purse was permitted, the boarding staff did not allow it.

There was no phone charger, uncomfortable seats, unprofessional flight attendants, didn’t like food

The seats are extremely small and very uncomfortable for a long trip , no space to even move the legs or keep the legs little bit folded, very uncomfortable

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

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.

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

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

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.
