Great service and comfort level. You can have more of vegetarian food options.

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!

This was an amazing flight. The crew was great. The service was great. The food provided was great.

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

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

First, Delta needs more flights to/from Miami. Second, a 1000pm leaving at 1230pm is unacceptable from their biggest airport world hub. Another aircraft could have been used such as the aircraft scheduled to be used in the morning for that exact same route. Yes, I did get me there but the lack of sleep the next day didn't help me enjoy my entire trip since I was busy with activities during the weekend. This can be and is expected from Spirit (going bankrupt) and Frontier (despite they're nickel and dimers). But from Delta's World Hub? That's totally unacceptable!

This flight was straightforward and without difficulty. Service was OK, but I continue to be underwhelmed by level of attention given to Sky Priority passengers.

It would’ve been nice for all that money to have a more substantial snack for free. I remember once upon a time getting a very nice turkey sandwich with Swiss cheese on whole wheat bread for no charge along with a drink. I guess those days are gone. it’s a little insulting being given a cookie or a bag of baked chips Going forward I’ll just bring my own.

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

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.

The morning in Hong Kong was ridiculous. Very chaotic. The flight was delayed. Missed connecting flights. Kathy should be more competent in getting the planes ready ahead of time so that flights can depart on time.. totally ridiculous and unnecessary. Very poor performance.

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.

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

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

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 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.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

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

Very delayed and uncomfortable seats. Nothing written in Urdu for Pakistanis. Tons of Pakistanis use the airline they should ensure the airline is accommodating them properly.

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

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

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

The food could be better. Toilets were smelly all along
