Same problem place in the middle so small Im 1,85 m so not good 👍

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

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.

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.

Likes: on time departure, new plane Didn’t like:very poor quality food, very limited entertainment.no amenity kit etc.

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

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.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

In never flown this flight, because my flight coning from Barcelona was delayed.

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.
