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.

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.

All great, because I was given a seat with extra legroom on this part of my trip.

Plane was good Crew was good Food was just ok Could have had more entertainment options But overall good

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

I had first class service from them. A little late taking off, but no major problem

Not good. Expected a lot more as far as excellence.

They made us deliberate waste time by holding our passports and boarding passes making us miss the flight

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

The hindu meal food did not taste good. Also the seats were not comfortable as compare to other airlines

The entire experience in Turkish business class was superb. From the friendly greetings including the chef, to the polite and classy service, all was wonderful. The in flight entertainment is one of the best. The food was the best I’ve had inflight.

I really enjoyed the food, only bad part on one of my flights my screen was a bit buggy but it wasn't a big deal it was one of their older planes so I understand that happens

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

Very good, it took a little too long for the food to come out on a service that left after midnight but everything was great.

Business class in Turkish airlines is like none other. They separate themselves and highly recommend it

I will avoid this airline as much as possible. Service was rude, and I don’t think the crew knew how to answer a CALL LIGHT. I pushed my call light on the ohare to Istanbul and the Istanbul to Thailand flight because I was very very thirsty. NO ONE CAME. I pushed it twice! NO ONE CAME! Why have a call light when no one will come? My experience was the WORSE AND I WILL NEVER EVER FLY WITH THIS AIRLINE AGAIN. The cabin crew needs to learn MANNERS AND BE RETRAINED on their jobs on how to be helpful and kind instead of being short with their customers and ANSWER CALL LIGHTS! I honestly wouldn’t be suprised this airline goes out of business.

Flight attendants were harsh, food could be better, took way too long to pick up food trays, were stuck with the crying babies the entire to and from trip. Restrictions of 8 kg for cabin luggage is ridiculous that’s barely 2 pairs of pants, shirts, shoes. There shouldn’t be any restrictions on the carry on luggage size except the checked in luggage. Attendants don’t even help with putting luggage in cabin space. Attendant picked up food tray and spilled cherry juice all over my husband and has the nerve to come back to ask why he hadn’t changed his clothes.

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

The cabin crew was excellent. They were fully staffed and very helpful. The food on the fight was quite good for surpassing my expectations of “airline food“

The flight was over 1 hour late taking off ,when I arrived in Abu Dhabi ,I missed my connecting flight to Bangkok so I had to wait almost 6 hours for my flight arriving in Bangkok at 6:30 am ,So I missed a whole day of my vacation and my hotel room sat empty so I paid for hotel days that I was not there. In Abu Dhabi there was a woman that worked the desk at transfers that was so professional, courteous , helpful,and may I say absolutely beautiful .she got me food vouchers for my layover and was a very calming presence. Besides that I will never use Etihad again I will pay the Xtra money . I'm sure they won't read or see this but it's my "2 cents" I'll use an airline that respects me and my hard earned dollars

excellent, staff and boarding were all seamless and no issues, thank you!

More leg space than other flights, but *maybe* narrower seats

I was charged $604 for a bag that weighed 17 kg. I was given three different prices until they landed on the most expensive one and didn't budge a penny. It's ironic and a bit enraging because the total cost of my ticket was $468. I've traveled the world and never experienced these kind of prices for only one piece of checked luggage.

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

A380 First Class Apartments were phenomenal. Comfortable bed and matress cover, superior vegetarian five course meal, shower, small business lounge and plenty of exercise walking around the aircraft.

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

Etihad broke my suitcase Also over charged me for luggage
