Boarding started too early stuck standing in the security corral for 1 hour with no update on when to board

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

The crew were kind and very helpful. Did not expect food service. Was served a warm soft sandwich bread , was delicious. Overall the service, the staff were great. Highly recommend others to try Turkish Airline

Changed to older plane with old set-up in Business class.

PLEASE GIVRE US PERMISSION TO BOOK SEAT NUMBER EVEN WITH FEES

Luggage never made it it’s been 2 days and no proper update

Amazing service on board in business class. The lounges are also great. The inflight entertainment could do with a larger selection and the food choices more but overall, very pleased.

Seat changes at the last minute Horrible checkin process Sad to see excellent airport with very poor service

The seat did not recline and we called the stewardess, he forced it to recline, but when we landed, it did not come forward because the seat was broken. The stewardess came, He tried to do it but couldn't do it, the flight commander came and spoke to us in a bad tone, telling us to get out of here, she waited at the head and acted as if there was a child and we couldn't get up, it was very shameful, I don't even know if it's true, but she said if you don't get up, the plane will not land and will keep turning around. Then a passenger pushed the seat from behind and it worked. Then we wanted to talk to the supervisor again, but she did not come next to us. We fly so much and this is the first time we encountered such a style.

Business Class Service was unacceptable. 7 flight time changes and delays

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

From Chennai to abu dabhi Abudabhi to Chicago Both flights are good , good service too

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

Unfortunately the flight was cancelled so I never got to go

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

I request kosha food all my flight but this flight didn’t imclude my kosha meal.

Nothing was good. Everything needs to improve. Everything was abysmal. Needs lots of improvement. The check-in and baggage drop at the New Delhi airport was manned by disrespectful people, horrible experience. We will never travel by Etihad ever again.

My flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Economy plus on a long flight with Lufthansa was wonderful. Service starts with a pillow, blanket, slippers and care package waiting on your seat. An it just gets better from there.

Review what was entered already in the same booking. Not sure we will use Arrant Grant, given what happened!

Great service food was very good and overall experience was great !!

When I fl with Bulgarian air, I am greeted with a bottle of water and a packaged cleaning wipe. There is a hot sandwich and a drink offered afterwards. Towards the end of the flight, there is a piece of chocolate and per request an additional water bottle. For the price that Lufthansa charges per ticket, it is embarassing that other airlines can offer better customer service quality on board. Also, some of the Lufthansa flight attendants act very entitled instead of being customer focused. Regularly the mobile lift for diabled passengers is missing... Every time when I fly with my 89 year old mother, she is being questioned multiple times whether it is okay to use the stairs ( she walks with two canes). Most of the times when we arrive in Frankfurt, the mobile lift is missing and she is urged to use the staircase. When I refuse to allow this, the flightattendants look at me scornfully. This is not WW2 where disabled people should be treated as second hand people... Then we all have to wait another 30 to 40 minutes on the airplane, while waiting for the mobile lift to arrrive. Does Lufthansa have enough money to waste on an airplane waiting for (on the average) 30 min for the mobile lift to come? I fly frequently and have experience mostly with Delta, United, Southwest and other American Airlines. Lufthansa needs to pick up their game on board, if they want to stay competitive and in the game...

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Keep an eye on your seat assignments - ESPECIALLY if you paid for upgraded seats - the airline moved us out of our prepaid seats THREE TIMES and I could only resolve it by calling customer service - who was very helpful. Expect to carry your bags down several flights of stairs for boarding on the tarmac.

It flight had a maintenance issue, that should be part of of preventative maintenance, and then they completely mismanaged the passengers on the buses. A terrible experience.

Didn't have bar code on our phone based boarding pass. People at the counter didn't notice. We walked to security, couldn't get through, had to go back to check in to get a paper boarding pass.
