Kayak works through chatdeal.com to process all ticket purchases. If anything goes wrong, you will not be taken care of at all. You end up dealing with a bunch of crafty indian people. I had to cancel my flight because I got Covid. After waiting forever over the phone, they asked me 400usd of penalty in order to get my 2 tickets refunded. When I realized I was scammed, I called them back, and of course the played dumb and denied everything, stating my tickets were not refundable. I contacted the airline, but they couldn't do anything, since I didn't buy the ticket directly from them. AVOID BUYING TICKETS VIA KAYAK!
