my experience with kayak was terrible. Team kayak just left me with a booking and limbo and preffered not to contact me.. Instead when I contacted the team they said the booking is cancelled. Seriously 5 days after booking u were waiting of my call to inform me of the incompetence of the team. This will be taken up with higher authorities

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

Too many changes in departure time (4-5 times before the actual departure time was determined) with no reasons provided.

My seats that I paid for were changed last minute and I had to sit in uncomfortable chairs

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.

Ok, where do I start, hmm! Good things first - the meals/food was tasty, the seats are comfortable and legroom in Economy was ample and foot rest with message roller is simply amazing, Wi-Fi Entertainment works well. Bad things - in-flight entertainment screens and remotes either had physical damage and or simply not working. This was the case for more than 1/2 the flight. Flight that was long haul - 12+hrs non-stop. If you want a cracker or a biscuit with your tea - forget it, they carry none. Feel like having a chilled beer - forget it as they will serve you room temperature always and every time. The crew seem young and inexperienced. Will I fly again, yes I would only because it gets me from Sydney to Delhi in 12.5 odd hours (fastest), otherwise I will never. It has been what a year or so since TATA took over but I have not seen any change, I really hope this changes.

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.

Poor behavior by ground staff in Mumbai. Very harassing. Initially they did not let me board with my little violin. They do not have the correct information. No concept of hospitality. The food on the flight was not good.

Information about when boarding would start was missing. Ground staff wasn't ready to provide any information with the answer being in the next 15 minutes any time we asked. (Took 2 hours)
