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

Flight was delayed by and hour but were informed beforehand

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

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

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!

Amazing and great experience, crew was available and took great care of my parents. Food was nice and so was the service. Aircraft from Dubai to Mumbai was not so great and was a big showdown of the aircraft service

The service was excellent. We flew coach on this leg of our trip and it was still very pleasant.

Emirates is always a pleasure to travel on. From the spectacular First and Business Class configurations of your big A380 and 777, to the Bar Lounge to, of course, your impecable on board flight attendance and their iconic uniform, now also even available for young girls. All the destinations that Emirates offers makes it an airline of choice many a time.

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.

The lounge staff at reception were inefficient and robotic. Boarding process was chaotic at the gate with no priority for business and first. At arrival into Dubai, no upper deck door . Food option and quality for this flight was awful . Thankfully the bar is always good.

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

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

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

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.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

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

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.

Seat selection screen while online check-in could include free seats to choose from and show the options before we proceed. Currently, it is auto-allocated and there are no options for free seat selections.

Liked leg room Disliked unable to book to sit with my family on same flight without paying extra

I liked the ability to walk and stand in the crew area. I hated the security check experience before boarding. The airport staff were so rude, yelling at us unnecessarily, delaying us on purpose, and even threatening to call the police on us!

Was ok except they send the baby trolley to oversize baggage office without telling me so we spent an hour looking for ir

Istanbul to Miami is a very long flight, somewhat uncomfortable, especially because the seating offers very limited space outside of business class.

Professional & courteous cabin crew. Food was very good even in economy class

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

The boarding was confusing everyone asking each other the same question is this going to Dxb? The seat was awful felt like your sitting on a bench. I would not recommend it to anyone.

Food quality and the overall service of the staff and significantly decreased. The flight was delayed at the Istanbul airport and the passengers were kept onboard for more than 3 hours. The staff didn’t kept the passengers informed and everyone was upset.

Professional staff we left on time. Meals were good. Added nice amenities.

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

My experience was amazing. Very friendly hosts and impeccable service.

Flights were extremely delayed, then canceled, our baggage was lost due to this and the service reps at the counter couldn’t be bothered to help us put in a missing luggage claim.

Service was courteous and attentive. Sat in the exit row. In exchange for leg room I had people tripping over my feet to use it at a hallway from one aisle to the other, had no access to films viaa viewscreen and no underseat storage for medicines or other personal travel needs. Next time I am seated there, I will refuse the exit row.

Entertainment was good. Food was mediocre. Service was mediocre. New plane was smooth

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Terrible. Had to go through customs and pick up our luggage. Then they said we couldn't make our connecting flight to MKE when we had 35min before takeoff. There were no other flights out on any airline so we would've had to spend the night at ORD. We were able to get a ride to MKE at our expense instead. Ridiculous that they would not allow us to try to make the flight, which we would have. Assuming rechecking the luggage was the problem. They should not have listed this as a viable connecting flight if there was no chance in making it. There was 4 people in our party.

Very good- my first flight with Airbus A380/800. Some of the food was not tasty , however. Everything else was excellent- the crew, the comfort, the process.

Food was good, flight is old, no leg room and restrooms are downstairs not easy for elderly people

Entertainment system have to be updated. Allied partners charging money for alcohol - in fact international flight.

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Much better than from Singapore to London, which was awful. London to ORD was business class experience expected. Friendly and helpful flight attendants, decent main course, delicious dessert, comfortable lay flat private seats.

Food was average. Better headphones seats were average at best.

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

The seats are incredibly uncomfortable. My luggage didn't make it on the flight from London to Nashville.

The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.

They lost my baggage and still waiting an update when I can receive it

The trip from Portland to Italy was great. However, the trip from Italy back to Portland was terrible. We started off leaving an hour late from Pisa to Heathrow, which then made it too late to reach our connecting flight. We were instructed by a flight attendant that we needed to go to "anyone of their colleagues" and we would need to change our connecting flight. Once we finally found someone from BA and stood in the long line of other passengers. Someone from BA came up to us while in line and asked if we were re-booking due to a delay coming into Heathrow. We told them we were, and she asked if we even checked to see if they already re-booked us. Nope, didn't know they would do that, so yes, they did in fact re-book us to a flight that would leave in 45 minutes, and we didn't have a boarding pass. "no problem just go through security and tell them you don't have a boarding pass" - It doesn't work that way. No one including security knew what to do. They kept sending us all over the place to people that didn't know what to do. Finally made it through security (after 30 minutes of everyone trying to figure out what to do with us). BA put us on a flight with Delta so we had to go to Delta to get our boarding pass. Flight was already closed, so Delta said "you need to go back to BA". Waited in line for 30 minutes due to only 2 people trying to help everyone. She got us out on a new flight that left the next day, with a connecting flight to Seattle. They put us up in a hotel that was obviously run down with a lot of passengers from BA. They told us to come down and get dinner - sent to a buffet and told we had to sit in the back of the restaurant. The buffet was not good. However, we hadn't eaten all day, so we were both starving. They had a vat of a meat sauce that said "chicken sauce". I started eating it (on tope of the rice they had) and just about chocked on a chicken bone and then found several other chicken bone slivers. The other dish said "chicken curry" tried that instead and there were whole large bay leaves that I didn't see (because it was dark in the back of the restaurant) and got one caught in my throat. Frozen mixed vegetables that said "fresh steamed vegetables" nope. Got to the airport early the next morning so we could make sure there were no issues. Flew out from Heathrow to Seattle (crew was great) landed in Seattle 20 minutes early, but couldn't get off the plane for 1/2 hour. Our connecting flight was in 2 hours. Got off the plane, and it took 1 1/2 hours to get our luggage. After 30 minutes, I went to BA's customer service desk to see if she could help. Her response was "it's not really my issue" after 3 passengers told her to make it her issue and find out what was going on, the luggage stared coming out. Needless to say, we missed the connecting flight again! BA had rebooked us with Alaska for our connecting flight. So glad they did, because Alaska was fantastic! The rebooking process was much easier and they made sure we got out of Seattle that day so we could get home. All in all, I will never fly British Airways again.

Once again I purchase a business class ticket and the seat is exactly the same as cattle class, the only difference being is that BA install a janky table over the middle seat so there is somewhere to place your complimentary drink, the tray table is just big enough for the small tray, so if you are not concerned about getting fed and watered on the plane or getting access to the BA lounge I would save your money and fly cattle, PS the cabin crew were exceptional in every way, shame about the equipment

My flight got cancelled the night before suddenly. They rebooked only half my flights back. I couldn’t contact them for help and then I had to book a separate flight on my own to get to the new flight back that they had booked me on. In Flight services were great. But once the flight got cancelled I was left on my own. Same experience for a traveling partner going to a different destination

This flag ght was cancelled at 3:30 AM the morning of departure! My son and I were nearly stranded until BA rep at airport found me alternate flights home. I had paid for seat upgrades, $75 for one suitcase, had no gluten-free food, had to arrive home at JFK instead of EWR, where my driver would have met me. That day was a pure nightmare!
