It was delayed for 2 hrs. Flight attendants were not attentive.

We boarded but due to a technical issue we spent 4.5hrs on the ground waiting for the issue to be resolved

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

They cancelled our flight, rebooked, cancelled that one. We are now flying New Zealand Air and need a refund please. How do we get it?

Wifi was not operational for the whole trip. Other than this, flight was well received .

Food no so good. Extra charge to much for front seats cost me £163 then other people sat near me for nothing 🤬

Comfort and customer service from most if the crew was great. The crew reassigning passengers should consider the presence of infants when reassigning seats. Unfortunately a couple of oversized passengers were relocated next to us, making this segment a bit uncomfortable, as there was not only extra leg space required. I ended up swapping seats with my husband so our baby wouldn't be impacted. My husband travelled quite uncomfortable as the reassigned neighbour shoulder and arm ended up on my husband's seat

Seats are not as easy to move as you would hope in premium econo Y

The plane was very old and uncomfortable. Service was very slow!

Flight from Dubai to Zagreb very bad cabin crew. Bad food

The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

Absolutely horrible aircraft with hard open ended wires hanging below the seats which were hurting. No phone charging outlets for a combined 15 hours long haul. Absolutely garbage service!

it was great honestly for the melbourne flight a kit with blindfold and slippers was probided to each passenger on the seat and the food was really great will definitely recommend people take turkish airlines for travel not just on the sin-melbourne route.

Boarding experience was a mess- both to and from Istanbul airport. No one knew anything. They asked everyone to line up according to their sit numbers- it was unbelievable. Business class had a separate line, but it was hard to find- I had to go through all that mess before finding it. Would not recommend

Everything was so smooth. It could be just a better temperature in the plane; it was a little cold.

Outdated business class on this aircraft, no flat bed, and even minimal recline. Couldn’t sleep at all. Laggy and outdated entertainment system. Food sub standard.

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.

Turkish Airlines overbooked the flight and they did not allow me to board the flight even though I had the proper boarding pass and was at the gate on time. Simply unacceptable.

Check-in was a mess, transfer flights were sepersted so no one could sit with their company. Some tickets were closed to online check-in without notice hand luggage allowances were not checked so oberhead bins were already full halfway through boarding.

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.

Old plane, dirty bathroom, hot cabin, non-functioning entertainment system (on my seat). This was a pretty poor quality flight. The crew was really pleasant and helpful. There was a medical emergency and they responded really well. Just pretty miserable for 3.5 hours.

Overall the crew were friendlier than similar premium airlines like Cathay or Singapore. Seat was good. Food was excellent.. the starlink wifi was a real plus. The entertainment was just ok.

Very poor No information given to why we turned around.. No one at airport to help

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

I didn't understand why I got dropped off at departures on exiting the plane at Doha aiport. I had to find my own way to immigration/baggage reclaim which wasn't easy as staff in the departure section just tell you ti scan your boarding pass. This was very poor b qatar Airways. I spent 2 hours soyung this out and once I got to get my suitcase it was delayed. So instead of getting to the hotel at about midnight I got there at three in the morning. I wonder why I upgraded to business?

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

Bus from gate to plane waited more than 30 minutes in a freezing temperatures of a/c. Plane temperature was very cold .

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

Unfortunately the flight was cancelled so I never got to go

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

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

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

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.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

Sits are very uncomfortable Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

crew as a whole is pretty mediocre. dont seem to care much for passengers. Asked 3 different crew for custom papers for immigration check in and they all said i could get it in the airport. have flown to india 3 times prior to this with Qatar and Emirates and they have always provided this paper ahead of landing to speed up the check in process. Also felt in general the crew is irritated and overworked. The one lady in my aisle from Chicago to Abu Dhabi was very pleasant but i was noticing the other crew were nice to each other but pretty cold with the passengers. Not what i usually have experienced from this type of overseas travel. Ive always felt the crew in qatar and emirates were overly sweet and pleasant but having seen the opposite this time i definitely prefer the former.
