Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

I lost my lock from my luggage, I don’t know someone took something from my bag.

We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

The staff on board were excellent. Kind, thoughtful, helpful - not just with me but with others around that I observed. Wonderful service.

Delayed and missed connecting flight. But Emirates took care until next day flight. Thank you

Very pleasant.The crews are very nice.Food were excellent.

The seating is spaced out nicely, The crew could have offer more drinks.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Excellent comfort and entertainment. Service poor..Food average with little choice.

Comfort poor, little leg room, cabin temperature too hot. No free entertainment. No complementary drinks. Overal experience poor and would not travel with them again.

Boarding was excellent except they did last call 30 minutes earlier .

i was not allowed to use lounge, although i had business class ticket, and nobody told me my ticket was not eligible to use lounge

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

A380 First Class Apartments were phenomenal. Comfortable bed and matress cover, superior vegetarian five course meal, shower, small business lounge and plenty of exercise walking around the aircraft.

The food could be better. Toilets were smelly all along

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.
