Never had a flight delay issue with Korean Air, that's why I always go with this airline.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

Food , drink experience were great with Cathay. Crew service was excellent. Clean toilet and full snack bars always, pilot took of 26minutes later when boarding at Hong Kong with extra US customs check at gate 9 for US flight, but he managed to arrive only 2 minutes later from flight tracker. Smooth flight .

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

Leg room wasn't that great. Other than that it was a good flight

If my return flight was not so much better, I would have given an excellent review.

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

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

It’s a business class ticket but they didn’t give a lounge access

Seat space was tight and uncomfortable. There was hardly any cushioning giving me a terrible tail bone ache. Getting and out was extremely cramped. We paid for seat choices and felt totally ripped off. Food was mediocre. By the time the servers served 2 or 3 rows they ran out of this or that option as we saw on the inbound trip also. This is infuriating. Entertainment choices were extremely limited for such a long haul. The screen froze on occasion and did not switch off when the on off button was pressed. When it did it came back on its own in 5 seconds. The airlines has gone downhill since last year.

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

excellent, the staff was kind and the boarding process was with no issues or hassle

Turkish Airline canceled our tickets in the very last minute, with our luggage and everything else, all prepared and good to go. It’s clear that they sold the tickets for better money to someone else. Bad, Bad, Bad business!!!

Awful seating. Bad food. Staff only have one bottle of water and no cans.

it was like a banya -so hot... They did provide a great experience with special food. one toilet broke midflight In general it was a peaceful and relaxing flight - for business class it was good.

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

nice and clean plane but the seats and the comfort was not what i expected. i expected more based on all the ads and reviews that i've read. I guess you get what you pay for in economy.

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help
