Never book through Kayak. They can offload booking to third parties that are completely horrible.

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

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.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

No seperate security check for business class passengers and average lounge, open air, so not properly air conditioned

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.

I would never have been able to make the transfer in time without asking for a wheelchair

We had to deboard using stairs. Why didnt you have the aero-bridge?

I am going to be just factual, not bad mouthing nor complaining, but this was my experience. With 3 pieces of luggage, I was told the flight from Mumbai to Dubai was cancelled due to flood. This was told not by the airport board which still showed the regular time of departure, but general stuff at the airport. No Emirates stuff around to direct the transfer passengers of the cancelled flights. By the departure counters with crowds of people, one by one, angry, frustrated, urgent conversations were going on. No announcement were made, no postings being seen, just private conversations. I still have 5+ hours of layover, so I let more urgent people settled first. However, the fact that no communication of when, what and where I should go was very unsettling. Basically no time limit waiting means, no meal, no sleep, no step away, no planning, no change plan, no telling of the family what to do. Nobody was able to tell you anything but asked you to wait, no chair, no space, no facility to freshen up. That went on for 10+ (from 5) hour without warnings and accurate communications. Email received from Emirates asked me not to go to Dubai at all, or boarding at the time that was passed. In other words, communication were very untimely, after the fact. That created more confusion instead. After changing several of boarding time, we were given the gate # and a boarding pass. However, the boarding pass still have the original time of boarding, so again, not knowing walking 30 min in the airport to the gate would make you late or not, therefore, still dare not to eat a meal. The flight arriving to Dubai was uneventful and I gave a 4/5 rating. I just thought the layover at Dubai would just cut short from 8+ hours to 2+ hours. At Dubai airport, I saw people sleeping on cardboard, knowing, these people got stranded but they dared to sleep because they know when to board and I didn't. Or these kind of delay are just so normal that people know what to do to pass time. Then the worst service and crazy thing happened. The boarding time on board for LA and at gate A9 was clearly 8:50AM. At 8:40, surprised by not having any boarding activities, then one single staff showed up and said to a few passengers that the boarding would be delayed without a time frame. Since only a few people know, I asked another Emirates staff at another counter, who simply said basically non of his business. I was shocked with that indifferent attitude. Yet every boards I saw show the same boarding time. What kind of system failure was that to prepare delay situation! How confusing and unnecessary chaos and anger that provoke. That poor staff had to repeat himself so many times, answered questions that he had no power nor information to provide nor solved. One an only one stuff to show up for 10 min, leaving the counter non-staff with board showing 8:50AM boarding. This was purely irresponsible from top to bottom of the entire airline operation staff. What kind of leader in a service industry would allow this to happen to their customers. Without explanation, after changing 3 times the boarding times, again, means you should not go to eat a full meal, because, when you found a mob at the gate. People who were stranded for 2 days were afraid of not getting a seat with a full plane. That would not be happening if the airline provide adequate guidance to each person, instead of just having 4 staff yelling at the gate at the same time to "control" the crowd, threatening no boarding and delay boarding. Finally, I was on board, hungry and tired, not sleep for 36 hours. I was denied with a snack of fruit. By the time meal was served, it was an hour later. Half way of the trip, I felt sleep in fetus position and did not want to move, happy I finally could have some shut eyes time. However, when I got up to the bathroom, I felt very light headed. Having sleep deprived, constipated for 3 days, dehydrated, I knew it could happen since my blood pressure usually was low closed to 90/60. Any lower then that, I could have syncope. Sure enough, I was on the floor just 10 feet from my seat and 5 feet to the bathroom. However, nobody called for help. I asked for warm water and juice to hydrate, came only with cold and icy drinks which I wouldn't take. I asked for blankets, one was given. Yet my shivering, needs to cover my head and multiple requests did not hasten to take the two blankets that are at my seat 10 feet away. I waited 10 min for that. While 2-3 staff surrounded me, nobody did the vitals until after 15 min, just the spirometer only of which did not work due to my cold fingers. The first reading was 86 and oxygen was suggested. But another supervising personnel came, fussed over another reading, ignoring my comfort and needs. Seemingly the reading of spirometer was the priority. By then, no oxygen needed. I had this fainting experience before, and I knew how to help myself. However, I was not being listened to but to be told this and that. Finally, I got better and returned to seat. One kind flight attendant said she would check back with me in 15 min. She did not come back. I felt asleep in that fetus position again and this time I woke up with a bad cramp at my left leg. Yet I needed to go to bathroom, the cramp was too bad to walk. So I stepped back to seat. When I tried again the second time, the other front leg got cramp. This time I dare not move but massaged myself. For all these 5-10 min, I called for attention. Attendants passed me by because they were carried with heavy load of blankets and stuff. Nobody answered the light. Then came landing and off board. I was asked by two attendants how I felt. I smiled and said "fine".

Service needs to improve. Air hostess do not register flyers request and we need to keep on repeating our request to them on multiple occasions

More space all around is practically essential on long international fights, and Emirates definitely delivers. But food selection and taste was only average. Otherwise, the flight was smooth and the cabin crew service was fine.

I bought Business class ticket but they treated me like economic class. No lounge allowed at check inn I have to take stuff out while other passengers have more than 25 lb in bag. Because I bought tickets from other than airlines . It’s discriminations from airlines to passengers.

Impressive as always. It is the airline of my choice, The dessert on the 2nd flight DOH-IAH was somewhat dry (the cake with cream etc) Check-in and boarding experience was fantastic, with the exception of CCU airport where chk-in staff refused to help with aisle seats stating the flight was full and accommodations were beyond him. Once I boarded there were plenty of available aisles. I was disappointed that this could not be done by self during online chk-in nor at the airport. Nothing more to add. Overall a good experience, TY QTR

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

The staffs were very good and helpful especially since we were traveling with a toddler

The boarding process was unpleasant. We had hardly any checked baggage, but they insisted on weighing the cabin baggage. While the weight of our cabin bag was well within limit, it seemed petty! The food was pretty disgusting. I had such awful food on the way over, that I brought some snacks of my own for the flight back. Glad I did. Qatar was consistent in that food was just as terrible on the way back as it was on the way over. The flight attendants were super-nice, though. If I had an option I would not take Qatar Airways again.

Transit , Too long for terminal change, for a moment I thought Qatar airlines going to Los Angeles by bus. Please make transit convenient and quick.

The seats did not have foot rest. If there is no foot rest you can’t sleep.

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar

only 3 meals in a 17 hr long flight. first meal after take off then nothing for 8hrs for people boarding at 2pm at orgin. you expect people to go without any food for 8 waking hours? there should have been 4 meals during a 17hr long flight. food quantity was also less. when asked for food the flight attended said they are about to begin food service then didnt do it for 2hours after saying that. terrible experience

Flies in the flight, broken seats, broken entertainment system and display - worst flight ever

Very poor experience for the price paid. Airplane interior including seats were old and jaded. Seat tray table did not work properly. Head phone was defective and didn’t work. Food was mediocre

The Air India lounge in Delhi , was very disappointing! The food was of poor quality and options were limited especially for vegetarians!! Beverages were fine. The in flight crew was excellent! . They helped me with my seat controls - the controls did not work without a hassle or assistance!! A very poor showing for a Business cabin!!! Post flight , the wheel chair passengers ( including Me) were “ shepherded and left waiting twice (an hour or more) before taking us to immigration! I chose to Fly Air India because I want. to patronize our National carrier with the hope that the experience will improve!!! Regrettably, I will have to look at other options for my next trip to India

If you are traveling to mumbai -- must try SFO - MUM direct flight. It's a game changer when you are traveling to India. Timings are well designed, optimal and makes the travel enjoyable.

One of my worst experiences. Nothing was working in the flight. Entertainment system was broken, seat was very uncomfortable, crew did not offer water until food was provided, lights were not working, attendant call was not working. In short everything was broken and duct taped.

Booked thru Kayak -> Indian Eagle. One leg of flight was cancelled after check-in (CCU to Del). Rebooked thru Indian Eagle cancelled again and rebooked. Cancelled once more now scheduled for CCU-BOM-JFK on Jan 18th. Let's see if this gets cancelled again. Would not book any tickets thru India Eagle - they are just a ticketing intermediate and for questions they ask you to call Air India. They "request" booking but apparently I got bumped after ticket was confirmed. Much better to book directly with Air India - avoid Kayak and Indian Eagle. I paid for Travel insurance can't see it any more on Indian Eagle site to contact.
