You guys need to check with your sub contractors. I had a confirmation email from airfare I don’t know then when I reach at the airport the check in offer did not see the ticket in the system. I had to issue another ticket at double the normal rate because I had to travel on the same day.

You guys need to check with your sub contractors. I had a confirmation email from airfare I don’t know then when I reach at the airport the check in offer did not see the ticket in the system. I had to issue another ticket at double the normal rate because I had to travel on the same day.

Joyful and pleasant. Food is amazing staff are so welcoming seats are comfortable. I would like to thank Shahrazad for her amazing service,

The seat was uncomfortable for me, less leg space and a tight space.

Very good - could have been more proactive asking for drinks as only got one all flight offered.

If you fly more often with Oman on the same route, you will realize the offered food is always the same. Quality of food is good, however, it is getting boring to know there is a soup or salad with goat cheese as starten and maincourse there is lamb, fish or vegetarian pasta. Pasta is always nice.

Man to Muscat the staff were poor. Missed bringing drinks to me & ran out of Beer. I didn't get a drink. Muscat to BKK staff excellent, food ok, and I was offered a drink.

Really a nice flight. , very comfortable seats and leg space.

Oman Air is on the relation Muscat-Salalah without any serious competition and that's to feel same as the metall bars of your seat in your backside after this flight. Don't expect anything other than being brought from A to B and you won't be disappointed

Everything was great in the business class. Seats 1A and 1C wouldn't recline properly. If i stood up then it did recline, even when the crew checked it he made me stand up recline it all the way and then he said "ok now you can sit" i just laughed it off.

We missed our connection due to technical issues with the plane. We were stuck in Oman Airport for 5 hours, had to overnight there, got rerouted to London, were denied boarding on the plane, were then seated separately (as a family of 5), did not receive any notification of our luggage being in London, were denied boarding for the AA flight to Chicago, and then all seated separately again. Finally our luggage was lost. Worst experience ever. Will never fly on this airline again

in today's time, an airline like emirates didnt serve drinks as requested, Excuse was full flight.

the seat is quite narrow compared to others. entertainment and food were very good

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

Fantastic service the managed to locate my checked bag on the plans as re-tagged it for my final destination.

We travelled in economy, were very satisfied with the comfort and keg space of the seats. Food was great compared to other airlines, the crew were very helpful and friendly. Since i was travelling with kids, i needed assistance multiple of times. Will be definitely taking long flights with Emirates from now on.

We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

The staff on board were excellent. Kind, thoughtful, helpful - not just with me but with others around that I observed. Wonderful service.

Very pleasant.The crews are very nice.Food were excellent.

They should resume the fast track for business / first class passengers

Premium Economy was not up to my expectation relaxation wise. The chair doesn’t extend enough. It is not economy but not spacious enough to relax and sleep. Food and services were excellent but I am not very keen about food in general.

no qatar did noting wrong Kayak messed up my whole vacation . Went early to check in at The Cairo, Egypt airport to find our I had not tickets to board , Kayak and/or Affirm never sent the money for my flight that I paid for and booked. So I had no flight at 12am in a foreign country and I had to scramble and find anther very costly other option just so that could fly home. Fucken horrible experience.

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.

Economy travel is really hard with no room to move especially when the person sitting beside you is an XL or XXL size person who if moving could hit your face

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.

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.

Indigo airlines is terrible. Staff is awful and so disorganized. They are so rude and unhelpful. I will never travel on Indigo airlines again!!!!!

The staff was great and probably that's the single most thing that distinguished this particular Qatar flight from my average typical experience. They genuinely wanted to please you and do their best.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

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.

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

1 hour flight. No complaints. Some drinks would have been nice.

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

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

Will never book any flight from Kayak and will never travel ithad airline

Same problem place in the middle so small Im 1,85 m so not good 👍

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.

Stewardess was attentive and was actively roamin to check the passengers on the biz class

My experience with Turkish Airlines was good. I didn’t get the meal I ordered. So I didn’t have anything to eat which was disappointing.

Very bad this airline changes my schedule date of travel and get me stranded in Istanbul for three days, paid for only one day hotel accommodation with only one breakfast and i had to pay for lunches ,and dinners and hotel accommodations for the two and half days

They changed the return flight to the next day and it interrupted the plans we had in our connecting city.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

What I did not like was that the airline changed my seat in Bodrum to one that was not in business class. Up until that moment I was in seat 1A. Then suddenly they told me I was in seat 1K and my "tablet was not working". - meaning my tv screen. I said that was not ok and they said go tell them in Istanbul. Each Turkish Air rep that I consulted told me there were no available seats in Business class. Finally I talked to the 4 airline representatives outside the lounge. When I talked to a woman and explained I wanted to change my seat back to what I had, A lady consulted something, asked me if I signed anything, then turned to a man nearby and spoke in Turkish. The man consulted someone and spoke in Turkish to the woman. Then she said my seat was now A1. Why was my seat changed out of business class in the first place? What would have happened if I had not talked to someone at the lounge? I am totally confused.

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

My wife and 7 months old baby had a terrible experience traveling, we paid extra for bassinet they didn’t provided.she missed her flight due to late landing of the flight, they were unsupportive to my family due to that my wife and kid suffered a lot.

"I had a fantastic experience with Turkish Airlines! Here are some things that really stood out to me: - Delicious food options, including a wide range of Turkish cuisine - Friendly and attentive flight attendants - Extensive in-flight entertainment options - Smooth and efficient check-in and boarding process Overall, I was thoroughly impressed with Turkish Airlines and would definitely fly with them again. The combination of comfort, service, and amenities made for a truly enjoyable flight experience."

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