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

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

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.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

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.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

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.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

I wish they could put the pre-tsa check on the tickets or global entry.

Couldn’t keep my luggage and had no choice. Ground staff didn’t even bother to explain why.

We upgraded to Business class paying approx. $1,300. Despite the upgrade, we were still required to pay an additional €70 for a checked bag. Furthermore, we were informed that another €70 would have been charged for our carry-on bag, as it was 3kg over the limit. To avoid this, we had to move clothing from the carry-on into the checked bag, which was both inconvenient and frustrating. Given the significant amount paid for the Business Class upgrade, we found this treatment to be quite appalling and disappointing. We expected a higher level of service and consideration for our luggage, and this experience did not meet those expectations.

Great flight, short and good attention. Didn't took any food so can't say thing about it

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

Excellent with no delays and according to the time schedule.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Flight LIN MAD. Checkin was fine (but I must admit that being a Platinum member I skip the lines). Security was fine (they have the new machines where you need not take laptops or liquids out). Longe was OK (BA). Boarding was a mess, the boarding gate personnel were rude and some should simply not be in a customer facing position. Flight in itself was fine, usual Iberia European coach. We were on time and actually time to deliver luggage was better than normal for Barajas

Bad business class. Staff totally not helping. Lights and chargers not working

my flight was canceled and rescheduled for two days later

Boarding was chaos. They did not board by group number and it was a free for all. We had a young child with us and were expecting pre boarding. Crew announcements were also poor as the crew member was speaking far too quickly to be able to hear what they were saying.

My seat was broken and unable to fully recline. My USB power point was not working and nor was the one next to me. It made a 12 hour flight feel a lot longer.

I liked having access to all the Harry Potter movies and the food was good. The staff was also excellent. The pillows and blankets could’ve been better as mine had stains when I arrived

Ok we did get an upgrade and the flight was delayed 45 minutes BUT without any bias. The crew were excellent, friendly, efficient and verging on exuberant, they all were so happy to do their jobs. Food excellent and the new safety video is fun to watch.

The luggage is still in transit and the ground staff at Heathrow airport very rude and uncooperative. If I was you, I would fire them straight away. Bunch of incompetent folks.

British Airways keeps canceling our flights. They have lost my trust in using their services again. I understand rescheduling once but twice? I am now arriving at home 36 hours later than the first flight that I booked.

One if not the best Airline I have traveled so far. My only complaint is that flights where delayed.

I will fly again with American airlines. It's efficient to get from A to B point, not too long layovers . Flights were on time, but box food on the long distance flight was dry, stale overcooked.

Free food and drink! Got a late start due to mechanical problems w a luggage loader.
