I like soft landing with Oman air both ways,food could have been better it was very poor

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.

Offboarding in Dubai was a bit confusing. The bus dropped us off, we passed the security, and then we were again in departure, no clue, no guidance on where to get our luggage

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Seat did not recline at all, wi-FI did not work at all. Those are both very unfortunate for a 14 hour flight. Crew and food was of course very nice as always.

Love that you can walk directly to your gate from the Emirates Business class lounge, very convenient

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

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

Very difficult to check in and almost missed flight. No room in seats and had a middle seat. I tried to create an account and check in before to change seat and unable to. I do not understand why I wasn’t on a Qatar flight from on Bengalore to Doha when they left at the same time. Disappointed in the Kayak booking process.

My journey with Qatar Airways from Ahmedabad to Jacksonville on 3rd February 2026 was truly exceptional. The entire experience reflected comfort, care, and world-class service. Complimentary high-quality Wi-Fi throughout the journey was a welcome luxury, especially on a long-haul flight. The vegetarian meals were thoughtfully prepared, delicious, and served with attention to detail, along with a fine selection of snacks and beverages. What truly elevated the experience was the cabin crew — graceful, courteous, and genuinely attentive, delivering outstanding hospitality at every step. This journey perfectly showcased the premium standard Qatar Airways is known for, and it left a lasting impression. I would gladly fly with them again.

excellent! movie selection just ok, but everything else was wonderful.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

Flight departed punctually on time. Unfortunately it seems because the destination airport is a secondary airport the airline sees it fit to operate a plane with lower comfort and offerings. There was no inflight entertainment, wifi or let alone a screen to at least track flight status for remaining flight time.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

In the business class it was everything wonderful. However in the economy is a hell. BTW. When I asked to search for tickets, I ordered business and I was offered options with economy, that was not clear in the order, so I could've acted faster to rectify it.

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

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

Unfortunately the flight was cancelled so I never got to go

I liked the crew, the food and the foot space. I did not like the comfort of the seats.

Early arrival. Good boarding. Deplaning this flight is very slow both coming and going. Baggage arrived quickly for Pearson

Ethiad wanted to charge me $1100 for 2 checked bags on a ticket that was $550. Nother the airline or airfare assist was willing to help before arriving at the airport. All parties said it was the other responsibility to help. Never flying ethiad or using kayak again.

Dirty and smelly lavatory and toilets in Wamos Air operated flights

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

It was great! Kept the time. Provided what was promised

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

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

Typically great service from Turkish with comfortable seat and amenitie, good food and great attention from staff.

Changed to older plane with old set-up in Business class.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

The fact that my flight was cancelled and made wait for 14 Fing hours to booka flightto a neighboring country.... never again

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.
