The flight was literally cancelled by emirates and you sent me to a scammer website of Underpricer.com for the tickets who still has not provided a refund for one ticket. Kayak has gone seriously downhill. If you are going to redirect people to a site then ensure they are reputable and not untrustworthy scammers. Am never using kayak again after this experience. And update your algorithm or whatever so you don’t send out auto emails checking on flight experience of cancelled flights due a literal WAR!! also I have complained about underpricer and nothing from kayak. So disappointing

The flight was delayed and the service was not good. All the new serve was beef and we don’t eat beef so we ended up buying our own meals at the airport twice.

I had a good experience flying with Emirates. All of the flights were on time staff was very professional and kind. So I had a positive experience..

The queue for checking for economy passengers was enormous! Only one desk open for economy faith s queue a mile long, whilst business and first class desks empty and unemployed. Will seriously consider changing to another next trip. Disappointed customer.

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.

Emirates is superb service. The A380 was very comfortable. The cabin crew is really helpful

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

The plane was very old and uncomfortable. Service was very slow!

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

The entertainment system did not work. And we waited 45 minutes in our seats after we landed before we got to the gate

This has been the worst experiencia I have had traveling overall. More than 3 delays, no one answering questions, no one at the AA counter. No one at customer service and after having to change transportation to airport and spend the night at a hotel paid by me, we were delayed inside of aircraft for more than 2 hours!!! Bad experience!!!

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

Very rude hostess. She embarrassed me in front of others. I went to sit after taking off in a different sit in the same economic cabin. Was the area where doors are. She come to me very laud and said: go back to your sit those sit are more expensive.wow! No diplomacy. Flight was super full except 3 of those sit. The only person in that row later during the flight occupied all sit laying down!. Once more disappointed at American Airlines. Early flight they lost my luggages for 4 days. Never refund money for replacement for some of essential items purchased..when I booked the flight I thought was Finlandair. I

Excellent service and always our preferred choice of airline. Was surprised we had to pay for soft drinks though. Other wise great airline and customer service!

The plane was warm and stuffy. The crew was friendly but got 2 orders wrong. I asked for sparkling water and wine with dinner and got neither. I asked for black coffee with breakfast and got coffee with cream. Service was so slow on my side of the plane they ran out of 2 of the 3 desserts at dinner and I was in row 12.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

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.

I liked the ability to walk and stand in the crew area. I hated the security check experience before boarding. The airport staff were so rude, yelling at us unnecessarily, delaying us on purpose, and even threatening to call the police on us!

Very good except the boarding process too forever and wasn’t organized by group. I had a heavy pack or I wouldn’t have minded. I was in business. There were no audible announcements in the waiting area about boarding and everyone packed into the boarding area. Then boarding stopped for a long time but the staff made no announcements to update waiting passengers about the holdup. The flight was good after we got on.

Awful seats, poor air circulation. Smelled like poop for 3-5 mins after someone used the bathroom. Child screaming for 13 hours

Inflight wi-fi is below par and difficult to access.

Just on time arrival and departure would make it great

Service was superb and the flight experience overall was great

There weren’t any gluten-free options for the snack that was provided. It was very difficult to get a boarding pass because we purchased through a third-party company. I had to get eticket numbers in order to prepare the boarding pass. You should be able to get a boarding pass with the booking confirmation number, but that would not work.

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

Seats were very comfortable and the staff too was very friendly.

More leg space than other flights, but *maybe* narrower seats

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

Lovely crew - comfortable journey despite it being an older plane.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

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

Dear Etihad Airways Customer Service, I hope this message finds you well. I am writing to express my deep disappointment with my recent flight experience on Etihad Airways, which took me from India to NYC via Abu Dhabi. My flight details are as follows: [Flight Number] on [Date]. My overall experience was marred by a series of significant issues that I believe warrant attention and improvement. These issues include: Bad Conditions of Washroom: The state of the washrooms on the flight was far from satisfactory. They were inadequately maintained and lacked the level of cleanliness one would expect during a long-haul journey. Seating Space and Comfort: The seating arrangement left much to be desired. The seats were cramped, uncomfortable, and the legroom was insufficient for such a long flight. The seats did not recline as expected, making the journey quite uncomfortable. Cabin Cleanliness: The cleanliness of the cabin, including seats and tray tables, was not up to par. The lack of cleanliness impacted the overall comfort and satisfaction of passengers. Excessive Noise: The flight was notably noisy, with disturbances and loud noises making it difficult to rest or concentrate. The noise levels were considerably disruptive. Food and Catering: The quality and variety of meals served on the flight left much to be desired. Furthermore, there were issues with accommodating dietary restrictions, which is crucial for passenger satisfaction. Hygiene and Sanitary Facilities: The condition of the restrooms was subpar, and essential hygiene supplies were not adequately provided. This falls short of expectations for a long-haul journey. Overall Experience: Regrettably, the combination of these issues significantly affected my overall experience during this long flight, making it far from the comfortable and enjoyable journey I had anticipated. I understand that maintaining high standards on long-haul flights can be challenging, but I believe it's vital to bring these concerns to your attention in the hope that they can be addressed and improved upon in the future. As a loyal Etihad Airways customer, I had higher expectations for my journey. I kindly request that you take these issues into consideration and work towards enhancing the overall passenger experience on similar routes. Your attention to these matters is greatly appreciated. Thank you for your time and understanding.

Boarding was very good, crew attentive and friendly, seat size comfy, screen size nice. However, the seatbelt segment with the buckle is extremely short, which made fastening the seatbelt very complicated. Moreover, the bluetooth pairing of the audio system didn't work. It was not possible to have proper audio. The flight info software didn't work, too.

boarding and flight very smooth. Crew very friendly and efficiant. Everything worked well

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Nothing can I say I liked. Food was horrible. Entertainment system didn't work. Crew's attitude was bad. They all were Chinese and wanted to speak Chinese. Baggage missed my connection at Frankfurt even though it was more than 60 minutes for my connection. It came in the next flight of 3 hours later at 16.15 Portugal time but they said they will deliver to me next day. I requested them that I had to go to a dinner meeting so needed clothes and there were medical documents in the bag which I needed for my Doctors appointment on the next day morning. But all no use. Then I had to take taxi, go to airport at 9PM and collect my bags myself and brought bags to my hotel. Will avoid Lufthansa at any cost and same I will suggest to everybodyelse.

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

Online checking, bag drop, ground crew and flight crew excellent. Seats better and more comfortable that many others in Economy, still narrow for 9 plus hour flights, but you manage. Drink and meal service a bit sparse but adequate, return flight was a bit less attended. All in all, a good experience. Lufthansa never disappoints.

I was served cheese that had mold on it. I brought this to the flight attendants attention and she informed her supervisor. They were apologetic and offered me a replacement, but I think that is extremely insufficient compensation given I ate bad cheese causing food poisoning for my birthday vacation. Both me and the flight attendants photographed the cheese, and I was told they’ll “put in a ticket” to ensure it doesn’t happen to someone else…….

Plane was very delayed. US agents unhelpful in connection flt and in seating. No real info given on delay.
