The plane seemed pretty old and the food was not good

The plane seemed pretty old and the food was not good

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

Very bad groud crew taking bags less than 7kg Bad food Old plane

everything was great. I don't use on-board entertainment at all (I just read or sleep), but I appreciate that I couldn't hear anyone else's!

The ground staff on Islamabad is horrible. The on board services are excellent.

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

A very disappointing flight on this Emirates business class. Staff were not efficient and service was not the e usual Emirates experience. Good was particularly bad with very dry chicken and drinks that I had to press call button before getting a drink as my food sat and continue to get cold.

Bad Cancel the flight Came back to work only 3 days after Horrible Won’t help with hotel while we stock Horrible Don’t fly with them

Worst trip ever from the beginning to the end I will never travel with that airline again. I made a big mistake by not going with my regular schedule flight with Qatar airline. Even underpriced cheat me of my 134 dollars I paid for special seats and they kept my money and didn't pay the airline for the seats for me.

More organised boarding process. It was a circus. Otherwise absolutely top class flight

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Overall good. Food choice in business class is a concern as same dishes on every flight for months. Crew is great and seats on this sector were fine . They need to have more variety in dining

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Moved seats, didn't accommodate requests to change seats even though other seats were available.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Being a platinum member, no attention given. No towel or tissue provided.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

No towels or tissue and chocolate and mint provided before arrival

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

they give hard time at checking, they not allow computer bag or purse

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Very good crew. Food service above average. Seats very small for a 12 hours flight.

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

They lost my baggage and I still have not got it back. Disgrace

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

Should have had business class line in immigration. Food quality suboptimal

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

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.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

I did not have a good experience in both flights of Etihad. First of all, when I was booking the flight, there were two options. The first option was a cheaper flight with longer layover (9 hrs), or a more expensive flight with shorter layover (2 hrs). I booked the expensive flight with shorter layover because I wanted a more comfortable trip. A few days before the trip, Etihad informed me that the departure time of my first flight will change 7 hours earlier, leading to an 9 hour layover, without giving me another option nor reimbursing me for the extra cost. They didn’t even send me an apologetic email for this change. Regarding the flight experience, I would rate it as mediocre. This is mostly because the pilots of both flights did their best to give us the worst approach to airports that I have ever experienced. In the case of the first flight they had to aboard the landing and took off again right before touching the landing strip. The captain said that it was due to wind conditions but the second time the pilot followed the same direction as the first time to land the plane.

Only 1 time food and drinks together was offered, for total 5 hours duration drinks and snacks was never offered. For some people food choice was not available, only veg was available. No entertainment option was there. Crew members were mostly back of the flight asking each other for KitKat and chips to share between them.

Lovely crew - comfortable journey despite it being an older plane.

It was just ok. Half the bathrooms were broke on the flight.

BAD!!! due to delay I missed my connection in MEX, had to pay for hotel and new flight for next morning increasing my spent for $1,000 usd

I didn’t receive my luggage until day 5 of a 9 day trip. During a layover a crew member made a very insulting comment about where I was visiting and where my partner was from in England.

Nice experience. Baggage arrival in Mumbai wasn't that quick and needs improvement.

More than 3 hours delayed. And they knew about it the night before already. I had a laugh when the captain said - don’t take out your frustration on the staff. Before take off Business class seats had very little space. My knees were digging into the seat in front

Lost bag - again. No help from staff at Nice - they have a handling agent who does nothing No emergency kit Try calling BA - they eventually found the bag - now on later flight. Trying to get someone to help in the short term is impossible. If I am unhappy - then I have to log it on a website. The agent said he was only able to help with future bookings - not assist in the chaos BA had caused. IF YOU WANT SERVICE WHEN THINGS GO WRONG - PICK ANYONE BUT BA. Personally - I'm joining ABBA (Anyone But BA) again.

Business class to Istanbul. Packed flight. Cabin crew seemed incapable of differentiating between economy and business passengers with regard to access to the WC which meant whole flight I had people standing in aisle and leaning into my aisle seat, queueing for the front WC. Crew put it down to a lack of curtain between the two classes. The seats, for a 3hrs55 min flight were just standard seats with middle seat unoccupied. So nothing special apart from the food, which was mediocre. Aside from the roast chicken dinner (‘special’ traditional British menu option, which looked poor but tasted good I gather). However 2 king prawns does not make a main course salad.

British airways has the most uncomfortable coach seats for international travel i have ever experienced. There is no leg room and when the person in front of you reclines their seat it nearly hits you in the face. There is not enough room for you to open a laptop in front of you or eat a meal. It’s ridiculous and i hope to not fly them in the future.

I just have to say everything was ok, nothing special, and business class is not as good as it used to be, business class sets are the same seats as the rest of the plane including leg room, only difference is no one is sitting in the middle row, they put a janky little table in there to give you somewhere extra for the free drink to sit

Food and entertainment non existent as we were only in the air 25 mins so totally understandable
