Airline reviews

The crew was very attentive and delivered great service unlike any other airline. It was our first time with Emirates. Our only critique is the food. Pasta pesto is not very common. Tomato sauce would’ve been more of a crowd pleaser. Beef curry sounds bad because curry can be very tough on the stomach. We were in row 26 and the pasta ran out, meaning no one wanted the beef which says something. The beef was just ok… The rest of the food was very good and generous. The plane speaker sound could be better. It was tough to understand announcements even with headphones. Although we did not need them this time due to the purpose of our trip, we were surprised that 2 checked bags were included. That’d be great for the future. It was unpleasant though that our personal items were weighed (we’ve never had another airline do this), especially when we didn’t have checked bags and almost had our carry-ons checked. Overall it was a good experience, but we wish the prices were friendlier for such a short distance (Miami > Colombia).

It was very exlent flight and thanks a lot kayak

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

I love to travel again and again in Emirates. Keep up the good work.

The stewardess took a picture as a gift , if you asked for it. Every thing was very good, Especially the food, big and tasty. The service was good, they served water several times, very frequent.

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

Some Crew were distinguishably fake in their interactions with passengers.

Better entertainment; the lack of it made the very long flight even longer

POOR CREW BEHAVIOR. RESTRICTIONS ON FOOD. FEELS LIKE ECONOMY CLASS.

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

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

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.

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

It was excellent service in the snow storm gives us hotel and transportation. It will be more better if u can add one more meal because it’s a long flight boring journey. If you give extra meal time passes faster and can enjoy the trip better

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

On this flight...fine. The one from India to Abu Dahbi, awful.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Nothing was good. Everything needs to improve. Everything was abysmal. Needs lots of improvement. The check-in and baggage drop at the New Delhi airport was manned by disrespectful people, horrible experience. We will never travel by Etihad ever again.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

Check-in experience, for business call please provide a premium experience

Everything. Employees offered to help me because I had to use a cane.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.

Poor all around experience. Sat at gate in Grand Rapids to Chicago for 2.5 hours. No food or water offered and no allowances to use restroom. Missed connecting flight to London and not offered any compensation including food or lodging. Not happy with AA, claims delay was weather related but no weather issues seen on radar. Take ownership for real reason behind delay which was actually the IT outage. Very disappointing and will not be recommending AA for domestic or international flights if this is the way that customers are treated.

Flight cancelled, lost luggage, crappy meal voucher. Nothing was good. Still dont have my luggage.

Not so good with their baggage handling as they damaged one of my check in luggage

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

We trusted KAYAK and Air India but no one is responds for the lost of baggage 🧳 2 (bags). My in laws are totally lost hope for this kind of situation to travel any more.

Worst International flight I ever had in my whole life time. Boarding is the worst of all and flight experience was also not good. Screens were not working, seats were not comfortable and lot more.

Very good compare to before . Nice food and tv was working

worst airlines I have traveled to so far. There was hair in the blanket and pillow they provided. On my round trip to India, not even once did the entertainment console work, the seats wouldn't recline, Some of the air hostesses were rude and not helpful. Not planning on using Air India till they have new planes.

One of worst flight. No Videos/Movies. The Seats are not good.

No in flight entertainment 2 toilets were out of service Crew was good, food is also good

Seats were broken. None of the entertainment systems were working.

Plane is old. Seats are broken. Entertainment does not work. Food is ok. Flight attendants are courteous and try their best. Take this flight if you get the cheapest ticket. Otherwise, look for other carriers.

Our flight was cancelled due to technical issues. Air India staff caused each one of us to go through nightmare before finally placing us in a hotel by 2 am. I was asked to share a single room with a stranger. I insisted that I cannot share the room as I needed privacy due to my vulnerable medical situation (Heart issues, High blood pressure, High Cholesterol and Type 2 diabetics). Even after explaining my medical situation and the need for privacy, Air India instructed the hotel to charge me Rs 4000 for the room and I was forced to pay the amount at 2 am (roughly $49). Air India should refund the amount I paid for my hotel room, at the minimum. Air India didn't have any Standard Operating Procedure to do what/how/when/by whom under this situation. Mom with babies, Elderly people and people with medical condition like me were forced to wander from here to there and talk to each person right from 10pm all the way till 2am. The Air India staff didn't have PA system to give a consistent announcement, instead they were murmuring on a one-o-one basis with more than 200 passengers. It was a sight of utter mismanagement and lack of commonsense. I will not ever, I MEAN EVER TRAVEL an Air India flight even if it is free, and will not recommend Air India to anyone I care.
