Very bad service and food variety will never come back again

Very bad service and food variety will never come back again

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

Everything was perfect. Staff were informative and professional and flight boarding, flying and de-embarking was smooth. I would certainly travel with Emirates again.

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Offboarding in Dubai was a bit confusing. The bus dropped us off, we passed the security, and then we were again in departure, no clue, no guidance on where to get our luggage

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Mostly good and consistent of Emirates service. Christmas menu was great initiative and tasted good. Taking the bus from terminal to the plane spoilt the experience a little.

The plane was old so the entertainment system was difficult to operate. The crew did advise earlier. The plane was landed and parked away from the gates, which added 20+ mins to the overall arrival

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

Flight canceled twice. Second cancellation with no notice. Qatar only got me to Copenhagen even thou flight from Copenhagen to Helsinki was code shared with QR they made me purchase a separate ticket for over 200€. At check in only 1 check in was allowed. I had to argue with staff to allow the second, carry-on sized, bag to be checked in for free. My original tix allowed 2 full size luggage as checked luggage. My 14+hr flight turned into a 60+ hr journey. 😢

Flight canceled by JetBlue for no reason. No good alternatives provided.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar, wake up and do it right by your customers, or they may not be your customers anymore.

You are the best, keep up the good work. Thank you for allowing me and my family to fly with comfort.i am waiting for upgrade some day. Thanks again

I wish I knew in advance that the connecting flight was by indigo air

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Older plane with finicky seats. Crew often seem to focus on "pet" clients and over extend services to some over others. I get less attention since I'm not a regular business class client. Regardless, I've paid the money and would expect equal attention.

It was great. The service was excellent and the timing was very good.

Very comfortable in business class. Excellent service. Good food. Smooth trip.

This was my third time using Turkish Airlines. I was well satisfied with the overall experience! I believe that no one is perfect and that everyday we are trying to do the best we can to help others by giving a part of our lives through service. I believe from what I’ve seen that Turkish Airlines, have come close to that service! I will definitely recommend and reuse their services again! Thank you!

They are absolutely impossible to get hold of. A death in the family caused us to delay our departure. They are impossible to get through to and after waiting 41/2 hours I was told they would not consider helping us. They cancelled our return flight and have not reimbursed anything. I strongly urge readers to consider a different airline.

Bag service at Iad airport was not nice at all. They served economy class first unvip first. This happened many times with different airports

Good overall. Seat spacing a bit tight between IST and ISB.

Turkish Airlines inflight crew was very good, however the ground crew was not very helpful. I had booked a wheelchair for my mother from Islamabad and she received the service there, but then there was no chair on arrival at Istanbul. The wheelchair crew said that they declined to take any person without a reservation and declined to help with the arrangement of a reservation. I had to use the airport buggy system to transport my mother who has limited mobility and needs a wheelchair. It was very disappointing and I hope they can provide manual wheelchair access to the public by a need basis, as sometimes there is a mix up or technical fault in the completion of the process, as it was in our case. Also, there can be an emergent need for passengers if they have illnesses like hypertension or diabetes. My mother has both hypertension and diabetes and has residual weakness after a stroke, therefore, she needs assistance. I hope that this text will be taken seriously and the administration makes the necessary changes. Thanks.

The crew is not focused on the guests but on their task!! No extra service. No business class amenities provided. A crew is not friendly if you ask for something extra, like tea. It takes 30 minutes, and you have to go them 3 reminders. Lack of friendliness, less but more of let me finish and go back to their group and Talk. Like a passenger is in on there way. So get your I gave you food just shut up

Bad sitting every flight not good experience with food either

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

Very disappointed to not have lounge access The shorter flight seats were uncomfortable

Seats were very comfortable and the staff too was very friendly.

Awful the whole airline arrived to check baggage and board our flight and the airline desk was closed where none of the passengers could check in baggage, asked for a supervisor and was refused a supervisor, called the airlines from the airport and they refused to refund the flights for their actions in the airport, Etihad and Garuda Airlines absolutely horrible customer service all the way around.

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

No entertainment except on app. No outlets working to charge. Good service

Dirty and smelly lavatory and toilets in Wamos Air operated flights

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

Service and food was amazing. Aircraft configuration is weird - stare at a stranger at take off and landing, during flight someone is crawling over your seat. It was lame.

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.

First time flying with them! Loved it! Specially the schedule from Miami and being able to come back directly to New Orleans :)

They lost my luggage on my way to Namibia (I was unable to review that flight as I was in the bush/off line) It took 3 days to get my bag and I had to pay $375.00 to have it transported to my location as it was over 100 Kilometers from that Airport and the local Airlink carrier would not got that far.

Unable to check in online until the morning of flight. No early baggage check available nor any BA personnel present. Poor customer service.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

We waited all day on a delayed plane. More than a 6 hour delay which caused us to miss all connections and spend a second full day traveling. Also missed a day of work that i hadn’t planned on.

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.
