Don't ever book flights on Kayak. They are horrible.I booked an AirIndia flight from USA to India in Kayak site. Due to Panndemic and travel ban, I had to reschedule my travel two times. Each time I rescheduled they charged $75 for Kayak Change fee + $175 Change penalty. My friends who directly booked the flights on AirIndia web site was able to make the changes without paying a single penny. Whereas I had to pay around $1200. Also, my friends were able to make it as open ticket. But these guys are saying that I need to $75 for cancellation + $200 for airindia change. this is ridiculous. Don't ever book with Kayak.
