I put the review all together for the first review

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.

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.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Good. Please add a non- applicable category to your questions.

Amazing crew, excellent food, business class seats seem a bit dated but are super comfy even for a very tall person. If continuing onto Taipei, the stopover in Bangkok is a bit annoying (queue at security) though the lounge is decent.

Boarding is fast and easy for economy class, food was ok baggage policies are good

Everything was fantastic! It was a short flight but the crew really went above and beyond to make it a great flight. I felt cared for with EVA.

Delayed due to no fault of flight crew. Efficient and worked well together.

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Flight was delayed for about an hour but overall good experience

The gentleman at the gate I think his name is RIE was exceptional

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

When getting to our seats a blanket, headphones and pillow where there already. The food was very good and plentiful. I liked when they came around w/hot towels to freshen up with. Slippers, socks and an eye mask was a nice surprise. My husband and I have mobility issues and the transporters were absolutely wonderful and helpful w/the wheelchairs at each stop. Getting from one gate to the next they were a blessing.

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

the cabin was kept too hot. couldn't sleep as a result

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

Awful seating. Bad food. Staff only have one bottle of water and no cans.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

old aircraft, some of the crew are not polite. I chose my seat to be window and I found it with no window and the seat was not operating...!!!

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.

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

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.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bag check in at DC was slow. Boarding process was slow more due to customers unfamiliar with how to board properly. Food and service was excellent!

The hindu meal food did not taste good. Also the seats were not comfortable as compare to other airlines

The first and longest leg, Washington to Doha, was in a 777 that was very loud. This was an older aircraft. The second leg, Doha to Delhi, was in a much newer aircraft, an A350 and was very substantially quieter. The service was good on both, though as always, the crew leaves you trapped with your meal tray for a really long time. Additionally, the flight crew seemed inordinately afraid of turbulence, keeping the seat belt sign on for long stretches when there was barely noticeable turbulence.

The first segment from Atlanta to Abu Dhabi was fantastic, but we got downgraded to a different aircraft from Abu Dhabi to Delhi. We were supposed to be on a flatbed business class when we booked it but just about one week before travel, we were changed to A321 Neo, which just has old-fashioned business class seats that recline but don’t go flat. While I fully understand that sometimes these changes have to be made for operational reasons, but I asked for some credit or compensation for that and I did not get any anywhere with that

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 !

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Same problem place in the middle so small Im 1,85 m so not good 👍

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

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

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

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.
