Airline reviews

The food was great; the attendants were pleasant. Waiting to onboard felt stressful, as passengers who had connecting flights at SEA had to be verified again for two things before getting a real boarding pass: passport and carry-on luggage weight. The boarding pass issued by another airline (i.e., the first leg of my trip) did not count. The S terminal at SEA was barren, with lots of sensory overloads because every airline was repeatedly broadcasting long lists of names of passengers who had not gone through that verification process. The carry-on luggage weight check seemed futile to me. I saw a woman who opened her over-weight suitcase to move some items into her shoulder bag. She still boarded with two huge bags with her. I assume this check is an endeavor of ensuring fairness of the overhead bin space or optimizing fuel efficiency when gas price is through the roof, but I don't know if either goal is achieved. Nonetheless I respect the crew's dedication to the SOP.

I put the review all together for the first review

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

My flight was amazing smooth and the attendants were so friendly and nice

More seat space More bathrooms Charging outlets Plane was old

Very nice, I feel I got good value for the price.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

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.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

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

Qatar Airways is an excellent service provider. The crew members were attentive and helpful. The aircraft was very clean. This was the longest leg of our journey, so it would have been nice to have more leg room for comfort. We appreciated the crew's service of four hot meals to all of us during this long flight. Also, it was helpful that the crew asked us to keep the window shades down for the entire journey, allowing the environment to get lots of rest during the trip. For families traveling with little children, this was helpful to them to keep them settled.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

Nice airline. I was in a really weird seat which had extra leg room, but no basket or stowage. And the people next to me were pretty noisy during the flight, so it was hard to rest. I wish staff came around to pick up trash more often as I had no where to put it except my lap or the floor.

All great, because I was given a seat with extra legroom on this part of my trip.

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

Seated in row 6 you are separated from business class close to the toilets. The is a high panel in front that obscures forward viewing, coupled with no window view. Service is limited as the area is not in view of the attendants. It is closer in proximity to economy than business class.

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

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.

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 .

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

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.

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

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

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

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

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

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