Everything I was good except food quality is very poor

We arrived in line for check in at 6:15 p.m. but did not check in until 8:00 p.m. The line for economy check in was very long, and all of the desks 03-13 were not open, although most of them opened sporadically. The crew on board were very nice and helpful, friendly and kind. It has been many years since we flew Emirates (at least 17 years), and we notice that foot rests are no longer available in economy, but we were lucky enough to fly in the upper deck and appreciate your opening some of your flights to economy passengers in the upper deck. We will definitely fly on emirates more often! Thank you.

Ove the A380 planes. Comfortable seats. Served great Indian food and Masala Chai!

Good flight overall. Good options of food on NY-Dubai-Mumbai leg. Not that good reversing back. The flight crew is courteous and professional as always. The seating was much more comfortable going into Mumbai than coming back. Cheers!

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Comfort good. Service as usual poor. Cabin temperature as usual too cold, about 15 degrees

The plane was clean and well maintained the crew members were professionals and friendly and the food was good

Flight was delayed by and hour but were informed beforehand

Emeritus is ***** Fly dubai is 0 we need better service for Fly Dubai

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

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.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

In never flown this flight, because my flight coning from Barcelona was delayed.

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

Both my luggages were never sent from Istanbul. After 10 hour flight from DC to Turkey and another 12 hour layover in Istanbul Airport, I would’ve at least expected to find my luggages when I arrived in Addis Ababa, but that wasn’t the case. After 2 hours of waiting at the luggage carousel, we were told that our luggages would be arriving the next day after midnight. I was already so exhausted, that I hated having to come back to the airport the next day. Thankfully, I received both my luggages the following day. It’s just, the whole experience was exhausting.

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

Here's a sample answer: "Honestly, I was really impressed with Turkish Airlines, but if I had to suggest one area for improvement, it would be: - *More efficient boarding process*: I noticed that boarding took a bit longer than expected, which might be frustrating for passengers with tight connections.

"I had a fantastic experience with Turkish Airlines! Here are some things that really stood out to me: - Delicious food options, including a wide range of Turkish cuisine - Friendly and attentive flight attendants - Extensive in-flight entertainment options - Smooth and efficient check-in and boarding process Overall, I was thoroughly impressed with Turkish Airlines and would definitely fly with them again. The combination of comfort, service, and amenities made for a truly enjoyable flight experience."

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

Absolutely horrible experience. It's an overnight flight for over 5 hours and business class does not have beds!!!!! I had a slightly bigger than economy class seat that was broken and not even reclining correctly. I should get a refund for this flight as they changed the aircraft to a small one and that is not what I paid the business class price for!

Seats are not clean inside the very dirty and need to improve

This time my experience was very bad. The Turkish Airlines changed my flight from Erbil to Istanbul from 8:15 AM to 11:20 AM few days before the trip. This made my transit in Istanbul about ONE hour. I have a special needs child and need extra time to navigate the huge new Istanbul airport with a child. To make the matter even more stressful the flight took off about 20 minutes late from Erbil which made our transit even shorter (around 40 minutes). The Turkish Airlines failed me on too many points despite clearly asking for help and as follows: 1. I asked the checking agent in Erbil for seats at the front of the plane to exit first and he stated the closest one is in the middle of the plane and I should ask the flight crew for help 2. I asked the boarding agent in Erbil to ask the flight crew to let us out first since we don’t have much transit time and she said she can’t and they wouldn’t listen to her anyway. 3. When we boarded I specifically asked the cabin crew chief the same request and after some discussion he wanted to get rid of me and said, they will help when we land. I again politely reminded the same person to help us when we exit before landing and this time he stated he would NOT be able to even announce to the passenger to let the people which short transit first and I should just deal with it like other passengers. He also told me to ask for help from the airlines staff at the gate when we get to the airport. This is very rude coming from the Cabin Crew chief. 4. I asked the airline crew at the gate which he had a cell phone to call the gate of my flight to inform them we are on our way and the agent pretended he didn’t speak English… Frustrating 5. I went to the Golf Card station (used to transfer passenger in the large airport) and asked for a ride and the driver there “shooed” me away pretending he doesn’t understand English while looking into his phone constantly telling me “Go this way, Go this way”. I saw first-hand other well able passengers on these cards and Turkish looking families get help on our way … which is clear discriminations. 6. We finally got to the Gate as one of the last people and we didn’t even use the bathroom on our way and made it back to Canada. I am extremely frustrated with the TKY this time and feel discriminated against just because I look from the Middle East despite I am and my child are Canadian. The Turkish Airlines operations failed me on too many points this time.

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

Great crew, newer plane, boarding was very disorganized, I still don’t understand why airline keep boarding front to back for coach instead of back to front

Terrible. They canceled 2 flights and then sent everyone by BUS from Rome. They should make amends by offering some sort of compensation.

Paid for a seat I didn’t get. Flight attendant said they would “report “ the problem. Food terrible. No service unless requested. Plane filthy. Seats falling apart. Broken footrest. Bathroom toilet held in place with tape. No gate announcements though delayed 2 hours. Is that enough?

The seats are horribly uncomfortable. We were in premium economy and paid a premium price yet, the seats were the worst! You could feel every structural bar in the seat, there was no padding, no amenities kit, and the leg rests were broken. Duct tape was holding another seat together. When we arrived at our final destination, Venice, my suitcase was ripped open, and my clothes were about to fall out of the bag. I would’ve been more comfortable if I flew a paper airplane across the Atlantic.

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

The flight was great. I don’t know about the food because I was asleep and they didn’t leave me any.

The flight was great, smooth and even a little ahead of time.

There wasn't a time for neither food morning entertainment in a short one hour hop over.

Flight on time, flight assistants super nice, business class very comfortable. The whole experience was very good.

When Stephen arrived with our wheel chairs - we were in excellent hands! He was such great help with getting our rental car and then reporting our missing luggage. When you are exhausted from traveling for too many hours, he was just what we needed to navigate everything! Give that guy a raise!

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

As seats on planes seem to get smaller over time and people’s bodies get bigger significant mismatches occur. I was seated in the middle of a four seat center row on a 9 hour 10 minute flight from Heathrow to Seattle. The woman seated next to me was such a size that she required a seat belt extension in order for her to fasten the seatbelt around her. She occupied fully 1/3 or more of both my seat and my table. Her and her stuff also occupied most of the space for my feet. Not an enjoyable way to spend on a 9 hour flight. My most miserable flying experience ever.

I thought we were screwed having to pay an additional $300 to pick our seats. My wife and I think it’s important to sit together on long flights and British Airlines use’s that against us charging over $300 on top of an already high fares. In the future, I’ll try to avoid using British Airlines, and KAYAK and stick to American or United.

The internet was horrible. Plus they charged me $25 for service that didn't work which should have been free since I'm Concierge Key. The flight attendant Rick Young was excellent. Greeted me by name and very attentive.

Fantastic! Great seats! Friendly staff! Amazing selection of shows and movies! Smooth ride! I don’t know what more I could have asked for honestly. They made flying a breeze this time around.

Surly rude flight attendants. I ordered the chicken and was given a vegetarian meal with no explanation and no opportunity to change it. I tried to order another beverage and was told by the young humorless flight attendant to “wait”. And she never came back. The seats were very uncomfortable and cramped. The last time I flew British Airways was many years ago but I remember it was amazing and the crew were very charming. This was a terrible disappointment given the cost of the flight.

Very long and took extra push back to BA staff to get a realistic flight after they made me miss my original direct flight. Eventually landed 9 hours late and incurred many extra costs with other missed bookings

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

Very dated plane. Seat was firm and uncomfortable. Entertainment system almost laughably outdated. Poor audio. Picture was always too dark.
