They ran out of the second choice of food was stuck with fish

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

toilets could be cleaned more frequently, everything else was pretty good.

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

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.

Flight was delayed and due to this we almost miss the connection flight

The flight was delayed by 3 hours, causing me to miss my connecting international flight. I then had to wait in the airport 18 hours for the next flight. The reason for the delay was a computer issue, not something outside of their control like weather. To add insult to injury, instead of trying to expedite the flight to make up for lost time, they ran a carry-on baggage check to verify every bag onboard belonged to someone on the plane, which took another 20 minutes.

झूठा है इंडिगो फ्लाइट में मील दिया नहीं जब शिकायत किया तो बोला आपको मिल चुका है

It took a lot of time to declare that the flight gonna be cancelled ☹️ very disappointed.

Electronic check in is must these days. Food could be better.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

Flight cancelled after 4+ hour delay. Indigo created a nightmare scenario and showed the most callus attitude towards the passengers I will refer to them was IndiNoGo!

Very nice and pleasant. Boarding was quick and the crew were responsive

IndiGo is low cost and therefore no frills, but is always a pleasant experience. No mood lighting and fancy features but clean aircraft, professional crew and absolute value for money.

Very hard seats. No food service, even though price is not competitive.

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!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

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

Food was below par Quality and None of the Entertainment systems were Working ..and we were unable to turn it off.. Due to the glare we couldn't even sleep for the entire duration of the flight ..

Very old and ill maintained flights. Seats didn’t have proper cushioning. The entertainment system was a joke. That’s the least one can expect from a 19 hour long flight.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

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.
