I lost my lock from my luggage, I don’t know someone took something from my bag.

Premium Economy is not worth the extra money you pay. You are neither economy nor business. The seat doesn’t recline enough to relax your legs. Maneuvering while seated is cumbersome. Don’t recommend Premium Economy at all.

Flight attendants were great. Comfort of seat and lie down bed pretty good. Food was very mediocre. Wine was good (red French wine) although I should have taken advantage of having more! :-) it was too late on the flight From znz—I was tired…then too early from Dubai. Woman sitting behind me dropped a full bag of garbage on my head while I was sleeping…orange peels, wet partially eaten food and very smelly food garbage which I literally had to pick out of my hair, off my face and away from my pillow. Not the airlines fault but still a very unpleasant experience.

Very good ..nice comfort..crew service was good..and no delays in time ..they always on time..

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

Different rules going from Dubai to Ahmedabad vs going from Ahmedabad to Dubai Horrible, only 1 baggage was allowed to carry on and no personal bag, i had to put personal bag inside carry on

Nice selection of movies and TV shows. Plane was generally nice, not the newest but nice nonetheless. However, Emirates should have cancelled the flight, as hardly any flights flew out of Dubai at the time. Flight delays and cancellation was poorly communicated and passengers were left guessing and to their own devices on what to do. Connection desks were staffed too thinly, there was one desk with more than a hundred clients and just one poor lady. When I had my flights rebooked, I was told meal vouchers can be scanned using my boarding pass, nope. Was told to comeback for my hotel voucher, none. Had to book my hotel voucher the usual way through Dubai Connect despite having been told twice to comeback to the counters twice.

Food was not eadable. Testless and not apealing. order for indian vegitarian, recived spice less. combination of main course and side iteams are far away from traditonal food, serve less iteams. , but eadoble. Thanks

Good could have been better. Emirates used to have really good food and lately it’s been sub par

Service for drinks and food really slow. Same food served on two long flights —LON to BKK. Would only fly if price was right - otherwise best avoided.

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,

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.

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.

Although a short regional flight, Oman Air continues to provide excellent service, and personal attention. I always find the Oman Air leg of an international flight less stressful and more personable.

Reduced cost for children to lounge Children’s area in airport Non spicy snacks Option of children’s meals Good films More children’s games and 2 player games Ran out of vegetarian meals

Omar airways mishandled my baggage, it took me 2 weeks to get my baggage back. It's been delivered to someone else.

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

Worst of the 3 flights so far. Food was not good, wasn’t ask my choice. Airplane was the A320 which was not as nice as the 787. Left and arrived late.

Went great, they even reopened the gate for me when I arrived late.

It was ok. Not the experience I expected from Turkish airlines

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

Boarding from Accra was chaotic and disorganized. Otherwise, it was a good flight with good food and customer service

We waited 4 hours in the flight to take off but then the flight was cancelled.

They use a smaller international plane and quarters are tighter, space smaller, and the flight is still 12 hours, then fight attendants are ruff, food is bad, cherry juice spilled by flight attendant and she comes back to ask why have we not changed yet could it be we didn’t have any clothes to change into and seat is all wet and we had to sit there for 12 hours

I recently had a deeply disappointing experience with Turkish Airlines, one I felt compelled to share. Firstly, the staff’s attitude left much to be desired. I encountered consistent rudeness both onboard and from the customer service team. To illustrate, I lost my eyeglasses on the plane. When I approached the airline’s customer service for help, not only were they dismissive, but they also mishandled the information I provided. Even though I had clearly mentioned my flight details in my correspondence, they asked for them again, only to later inform me they couldn’t locate my glasses. Moreover, the flight itself was delayed by three hours, adding to the frustration. Given this experience, I strongly advise reconsidering before booking with Turkish Airlines

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

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.

My carry on bag was taken by Alaska Air as we boarded in LAX! She said there was not room. There was plenty of room. I told her that my meds and personal items were in it. She did not care. She said it would be sent to my final destination, Nairobi. Well it got to Nairobi the day I was to fly home. The handle of my bag was crushed so could not retract. So I had to remove it. I had to buy converters, malaria medication. personal items. I filled out the missing form at the Nairobi airport. I asked that it be shipped to the Kisumu airport. When it was obviously not going to make it for my time in Kenya. I asked that it be sent to John Wayne Airport. NONE of that happened. I only knew it was at Nairobi because my air tag indicated it was finally in Nairobi the day I was leaving Kenya! Now I need to purchase a new carry on bag!!!

Was unable to check in via app or website with supplied booking code (something to do with flight being operated by a partner airline, although the code didn’t work on the partner’s website either) Specified a vegetarian meal during booking, but that somehow wasn’t captured in airline’s system By the time flight crew got to my row, now vegetarian food was available. Had nothing to eat on flight from Philadelphia to Doha! Flight attendant was completely unconcerned and actively apathetic to the situation

Only negative was dostancevto transfer in Doha with no big golf carts to help us. Walked over 2 miles.

need to improve management and air hostess services. Rest of it’s OK.

Service and boarding is good in brussels But in Qatar, boarding needs to be improved and waiting in very big queue for boarding. Parents with kids needs to be given some priority also.

I lost my baggage and it’s been three days didn’t able to find out. Also ticket was issued for qatar airways but they ended up board me on to Indigo from Doha to Hyderabad. My trip made miserable without cloths.

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

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.

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

i was not allowed to use lounge, although i had business class ticket, and nobody told me my ticket was not eligible to use lounge

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.

One thing is very important is you people not giving seat arrangement together to couple, senior citizen. You have to take care of senior citizen. Do not look about money. Money is not important everywhere. Make relationship strong is very very important. I like Etiyad air line out of all air line. Food was hot and delicious. Air hostess gave very good service, nice attitude, very good behaviour. I gave 10 out of 10 marks. Thanks Jivraj

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

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