Bad seats. Broken entertainment system. Charging port not working. Seats were broken worn out. Crew was amazing. They helped as much as they could.

Why should I rate entertainment if I’ve not used? You don’t have NA - Not Applicable option.

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

only passenger seats are too much narrow. It’s not comfortable otherwise it’s good. Seats are very important because it’s main in Travel

Miss my flight from delhi to amritsar due to lock the luggage door of airplane.and there was no more flight even for next days and they not refund the fare. I took bus grom delhi.. bad experiance.

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 was through bus even though aerobridges were empty. Major mess

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

Poor hygiene in the lavatories. Limited control of passengers who often were up standing around my seat talking loudly with their friends.

Extremely bad experience compared to Vistara. No priority in check in, no priority for boarding. No upgrade. Seat selection is paid. Curtains were dirty. Demo bag was dirty. Warmth of the crew was missing.
