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.

It took almost 4 hours to collect the luggage from the belt in Lagos. Really pathetic. Flight attendents from Dubai to Lagos were very busy and were not responding at all.

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

Food was great. More vegetarian options on menu would be great!

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 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.

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.

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

I am a big person and have back pain and swelling in my legs, so this was a challenging flight due to confined space. I didn't find the crew very friendly either. I will think twice before flying long distances with Qatar again, due to the lack of legroom.

It was little disheartening and disappointing. Although flight staff did a good job. But customer service didn’t do anything to resolve my issue.

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

It was great. The service was excellent and the timing was very good.

Seat assignments for family traveling with 2 children. Loud crowd during sleep time

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

Some of the best service I’ve ever seen on an international flight! The staff were super friendly and accommodating. The food was excellent with lots of choices and attention to detail. The seats are kind of old and narrow, but I have wide shoulders. The only area for improvement was making the cabin a little cooler.

everything was excellent except for the meal on the fight from the Istanbul which was disgusting, the only choice of food available was pasta which was served frozen.

Our flight was canceled with no rebooking offered. We are still waiting for a refund and had to book a very expensive flight to return to Toronto without any compensation or help from Turkish or flight hub. Extremely poor service during a time of crisis, speaks volumes about the type of airline and flight hub as a disaster of a company with zero accountability

Majority of the staff were simply awesome and very very supportive and helpful

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

The crew is not focused on the guests but on their task!! No extra service. No business class amenities provided. A crew is not friendly if you ask for something extra, like tea. It takes 30 minutes, and you have to go them 3 reminders. Lack of friendliness, less but more of let me finish and go back to their group and Talk. Like a passenger is in on there way. So get your I gave you food just shut up

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

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

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.

Good one but just notice that you have to ask several time to get water or coffee .

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.

No entertainment except on app. No outlets working to charge. Good service

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