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,

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.

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

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

The crew could have offered us seats together as the flight was half empty. But overall, the service quality was good as well as the food and entertainment options. Would love to fly Oman Air again.

Smooth until we get in the plane it was so small and uncomfortable the whole flight, apparently they have Changed the plane and I don’t know what was the problem this flight is from mct to phuket - on my way back everything was perfect

Staff were attentive and professional, and managed to be personable and accomodating at the same time. Oman Air has become my airline of choice.

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.

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.

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

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

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

Plane was old and seats uncomfortable but staff were friendly and helpful

Flight never took off. Boarded after multiple 30 minutes interval delays for hours.. then after an hour onboard, captain announce cancellation and back on the bus to the terminal with no information and everyone to fend for self.. Emirates did absolutely nothing to communicate either electronically or announcement. It’s unprecedented I know with the flood but lack of communication creates anxiety and extra pain for staff. Emirates should do better.. no supervisors monitoring floor and passengers abusing them which isn’t right but should Have had supervisors monitoring

More space all around is practically essential on long international fights, and Emirates definitely delivers. But food selection and taste was only average. Otherwise, the flight was smooth and the cabin crew service was fine.

I wish any of the US airlines operated like Emirates

I never got to take my flight because kayak constantly changed my flight, sometimes without telling me. I finally called to verify exactly when my flight was scheduled, only to be told my flight was canceled all together. I had less than a month before I was supposed to leave and I was told it would take 20 business days to receive a refund. So I never got to take my trip to Dubai. Kayak is horrible with lousy customer service and I will never book another trip with them every again.

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

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.

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

I felt the AVM was bad. They could have done better and felt the route was much long theb expected otherwise it was good experience.

Seats were in disrepair. Seat back pockets were all broken. Seats recline very far, which is comfortable for occupant, but confining for person behind.

The flight attendants were very attentive and recognized that I had a very short layover for my connecting flight. The head flight attendant went out of his way to find out my connecting gate and ensure that I expedited the aircraft quickly.

Delays and no explanations nor apologies. Last 4 times I flew Turkish the flight was significantly delayed. I will avoid this company in the future

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Friendly crew. Computer systems had trouble keeping my Star Alliance status linked to my reservation. Inflight Wi-Fi was slow and expensive. No standard power outlet, but medium-power USB-C port slowly charged my laptop. No option to buy whisky in economy.

We were traveling first class. Checkin counter lady and her manager, both were in bad mood and did not treat us well about checking in the handbag. The gate agent took care of it right away. I travel Turkish twice a year in first class. No one has ever refused to check in the hand bag. Not sure, why this agent and her manager refused. Everything else was excellent.

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

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

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.

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.

I recently travelled in Business Class with Qatar Airways, and overall, it was a pleasant experience. The cabin crew stood out for their kindness and professionalism, making the journey truly comfortable. The food exceeded expectations and was exceptional in both quality and presentation. The boarding staff was courteous, though I would like to mention that the staff member responsible for checking tickets during boarding could benefit from additional training to be more welcoming. A warm and hospitable approach would enhance the passenger experience significantly. However, one aspect of the journey was particularly frustrating. The in-flight entertainment system was disappointing, as the headphones provided did not work at all due to a loose connection. This significantly impacted the experience, especially since the flight also lacked Wi-Fi service. Addressing these issues would greatly enhance the overall travel experience. Lastly, I would suggest implementing a section-wise boarding process to streamline the boarding experience and minimise potential challenges. I appreciate the efforts Qatar Airways puts into delivering high-quality service and hope to see these improvements implemented in the future.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Not good. Expected a lot more as far as excellence.

food in Qatar was terrible. I had ordered asian vegetarian meal but the food lacked any flavor. Choices of entertainment was also very limited. emirates is way better in terms of food and entertainment.

Was humiliated at Doha airport, treaded like a cattle class traveler, I hold platinum pro status with AA and I don’t fly economy even domestic but was made to travel in the middle seat in economy class and boarding zone 3 and was denied lounge access at Doha airport. Never was humiliated like this before.

Cabin crew The only issue was that there was no space for our carry on luggage near our seats We had to put our luggage in a different wing And when I went to collect it, none of the crew knew where they placed our luggage

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.

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

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

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

I request kosha food all my flight but this flight didn’t imclude my kosha meal.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping
