Everything was great except the boarding experience. After the check in, they "packed us" in a small area, very hot there. It would be nice to be aware of this, I'd wait on the outside area

Everything was great except the boarding experience. After the check in, they "packed us" in a small area, very hot there. It would be nice to be aware of this, I'd wait on the outside area

Very good from the beginning to the end. Amazing experience

Chaos at the gate while boarding - no clear signs or announcements

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

Fly Dubai takes low cost and thrift to new depths in terms of service levels, terminal 2 is grossly inadequate for capacity and resembles a crowded buss or railway station,, the fly dubai( Emirates) flight is never on time(was 2.5 hrs delayed), and this is not an isolated experience, the flght air conditioning was turned low while we waited on the tarmac for take clearance to save fuel, should say more!!!! The depths! I only fly this airline from a compulsion, emirates code shares for connections to Muscat

They changed the flight time without telling us and were unwilling to help with rebooking because we booked through orbits/kayak

I liked everything: the service, the food, the cleanness. I flew last year with Qatar Airways, so I can compare. Emirates did much better! Especially their meals and service.

Emirates did great! I liked the service, the food, cleanness, and the flight was on time. Much better airline than Qatar Airways I flew with last year.

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

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

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

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!!

Looks like a local flight. Food was horrible. No entertainment system.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

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

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

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 !

Good one but just notice that you have to ask several time to get water or coffee .

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

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

It’s a business class ticket but they didn’t give a lounge access

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.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

Flight was cancelled by air India. There was no explanation provided why the flight was cancelled. Found out that the flight was cancelled because the Iran air space was closed. Meanwhile, all other flights passing through that region were operating without issues. When asked to refund money for the tickets, being told that “ As checked, we wish to share that Flight AI 116 on 15 January 2026 from New York to Mumbai was cancelled due to Iran airspace closure, which were beyond the airline’s control. While such events can disrupt travel plans, we appreciate your understanding and patience. Our team remains committed to ensuring the safety and comfort of all passengers and takes all necessary measures to minimize any issues. However, we must inform you that compensation is not applicable under these extraordinary circumstances, in accordance with the relevant regulations.” Completed unacceptable and unprofessional behavior!

Needs lots of improvement starting from crew/staff attitude, cleanliness, better quality food & in flight amenities.

Horrible flight. No entertainment or WiFi for a 14-hour flight. No explanations either. I’ll never fly Air India again.

Several seats in business class were broken. Some would not recline, others had other problems. They need to really update the seats and AV.

Never can get flight and nof light for three days .finally travel by bus. Very bad experience.

Food not of any international or even Indian standard. We have many cuisine available but only paneer & sundry items. Improve & provide some good indian items. Entertainment website or channel out of order.

First and the foremost I was shocked to see airindia standards have come down so low . The food was horrible . They served us 3 meals for vegetarian and all the was paneer . The orange juice was not at all cold it was smelly . After you take this heavy price air India should learn from other air lines . I at one point felt like throwing up . After all this when we landed we were not given landing slip . We had to wait for 45 min at the immigration just because no one was given landing slip . To top it all we were 3 passengers and had checked in 4 check in luggage . Out of which 3 have not yet arrived . Basically status says the loaded it in our flight ( this was a direct fight ) and it never reached . We are still waiting . There is nothing great to tell about our flight . The he only good thing was the crew were very helpful .

Lay out shows 1st row and second row given after taking payment. It's a fraud

The seats were extremely uncomfortable. Air India seats used to be very comfortable . with sufficient legroom. In this aircraft there was no legroom. It is a shame that for your profit margins you are trying to pack people like cattle on these long haul flights. The food was terrible. The bread was hard like a rock. Mr CEO of Air India, why don’t you take a flight in economy from India to USA and experience the hardships first hand. It is utter disgrace

Absolutely nothing. Cold and unpleasant airline staff, and to top it all, the entertainment system was broken. Really harrowing experience.
