It's good overall. Flight was packed. Inflight entertainment choices were lacking.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

The food on this flight from NRT to ICN was average. The staff were very friendly, but the flight took about 60 minutes longer than it should have because the pilot was only flying at 330mph instead of 500-550. Not sure what the reason is for that, but it meant for a much longer flight.

Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

My second flight wasn't better than the first one. And this is 14 hours trip, crew came out only to offer food and the choices was poor. This food choices are good for Asian people but not for westerners. The breakfast kind thing was a corn sausage really disgusting. The air-conditioned blower really blow high and cold, turn out on my arrival to feel seek, that makes the trip uncomfortable. The crew didn't not really come out during the trip to offer drinks or snacks. No fruits available. Very poor service

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

Seats very small and unable to pre purchase internet or seat upgrades

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Damage lagguage, They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Same situation saudi lost my pram and car seat and damaged lagguage

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very bad

Apart from chaotic boarding - which I totally understand was outside the control of gate staff. It was comfortable mid haul flight. Well done to cabin crew for their patience and hospitality with largely elderly passengers returning from pilgrimage.

The intettainme is old stuff and difficult to get by WiFi and the chair is not comfortable at all although the staff were excellent but beyond their limited

Overall a great experience, no movies were available. Bags were delivered a bit late. Seat controls were not working well. I couldn't make my bed fully flat.

It is almost 7 hours journey ,you should have provided with TV entertainment and mobile charging

I think the staff was short. Being Vegan, I ordered a custom meal. The meal was not provided both two ways. I assume they forgot. They were short on staff. It was taking for ever to provide service. people were getting restless.

Very poor show. Flight got delayed due to fog in Lahore. This is understandable. However, no arrangements were made for nany hours, once some things was organised, there was no leadership, no support to families with children's, disabled passengers. Took to hotel where it took 3 hours to sort out room allocation, that after finding partner to a minimum of 4 people. Couples were asked to find another couple before room is allocated. After 2 5 Hours of reaching room,return journey started with total chaos, no leadership at airport. Several derours to finally get new boarding passes. Asking the reason why flight was cancelled, the Saudi airline staff recommended using other Airlines in future.Finally boarding nobody inside the aeroplane helping old, illiterate to find their allocated sears. Sort out luggage storage. All the staff stayed in their kitchen areas to let passengers sort out. In-flight service wad good. Overall very poor experience.

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

United left one of our bags back in SFO but that’s not my real complaint. The complaint is how it all went down. So we checked in the day before online and were told we could use the quick drop for luggage. So the next day I used baggage quick drop curbside at SFO. The agent mistakenly didn't tag my bag as he put my bag on the conveyor belt untagged. We immediately alerted him he had not tagged the bag. I walked with him to the baggage service office to find my bag and tag it. We waited outside the office for 10 mins. He came out and said everything was ok and the bag was going to be tagged and on my flight. We received a text that one of our bags was on the flight but the other was not. I alerted my first class flight attendant immediately upon boarding the flight. She was helpful and said she’d get it sorted out right away. She called over the gate agent. The gate agent used my bag number and looked over information on her device. She said my bag was on the flight. The flight attendant was standing with her, looking at the device, and also said “yep it’s on the flight”. During the flight the flight attendant made reference to how reassuring it must feel knowing the bag was on the flight. Upon arriving to IAD we received a text that my bag was not on my flight. The text said my bag would arrive to my final destination LIS 24 hrs late. I understand that mistakes happen. I was totally ok with my bag mistakenly not getting tagged at the quick drop. I was fine with walking down to baggage services to tag my bag. But, what I am not ok with is that the United staff said they fixed the mistake two different times, assuring me twice that my bag would be/was on the plane…and it wasn’t. I expected better attention by the employees, for them to do what they said they were going to do. We also spent extra money to upgrade our seats to first class, including the entire return leg from Lisbon to San Francisco because we wanted a smoother and more relaxing travel experience. Our money was not well spent. We will not be using United for travel going forward.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Horrifying! And I am almost 2 million miles with United. Late by 3 1/2 hours. Worst: after two hours on the plane waiting, they decided that one of the tires had been damaged and then decided to change it. Another hour and a half to change the tire!!!!! NO EXCUSE FOR THIS. The crew didn't even offer a glass of water until we had been on the plane for FIVE hours. This is the worst airline in the world. I'm simply stuck because they fly on the only routes I need.

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

The check in process at Istanbul airport caused my family a great deal of stress and disappointment due to the following factors: 1) WE HAD TO PAY US$330 for check on bags, despite holding Economy tickets that Turkish airlines website clearly states that flights from Istanbul to Miami had a 2 checked bags allowance. 2) Airport staff not only lacked empathy for senior travelers (75 yrs old and 71 yrs old), but were also rude as well. The supervisor at check it offered "if you don't pay for the bags, you can just remain and sleep at the airport for however long you wish. What a terrible way to treat customers !!! 3) We were bumped from agent to agent to agent FIVE times, showing everyone the communication we received telling us we had the 2 bags entitlement. Two elderly people lugging 4 suitcase around and around the Turkish terminal. Again, what a sad way to treat customers !!! 4) We need a case opened to get a refund for the amount we paid. Something is amiss, screams unethical, and sounds unscrupulous......At First , we were told we must pay for 4 bags. All of a sudden, it became 2 bags, and finally all 4 bags were checked on with payments demanded for 2. Why did it vary from agent to agent???? 5) OVERALL, A TERRIBLE AND SUSPICIOUSLLY UNSCRUPULOUS EXPERIENCE FLYING WITH TURKISH AIRLINES. WE ARE TERRIBLY DISAPPOINTED AND SAD THAT OUR VISIT TO A BEAUTIFUL CITY ENDED IN SUCH A HORRIBLE EXPERIENCE

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

One of the best flights I have been on in a while.

Here's a sample answer: "Honestly, I was really impressed with Turkish Airlines, but if I had to suggest one area for improvement, it would be: - *More efficient boarding process*: I noticed that boarding took a bit longer than expected, which might be frustrating for passengers with tight connections.

Not worth pay business class and get service economy class

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

In sharp contrast to the modern glitzy airport, boarding facilities were primitive. Passengers had to board buses and walk up steep stairs in bitter cold with carry-on baggages. I found no reason why aerobridge was not provided.

Service and food were decent, seats are a bit too narrow. Leg room is normal. Bathroom should be cleaned more frequently. WiFi is cumbersome and should be simplified.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

Same as before boarding process and lack of crew experience in the process
