how does makemytrip.com or yatra.com make money? makemytrip business model?

ANSWER TO THE ABOVE QUESTION Basically, makemytrip.com website makes money through CPC advertising as I can see various clickable advertisements around the site. And they may also charge Hotels/Local agencies which want to partner with makemytrip. In addition to that, they also make comission money from selling travel tickets. In fact, they accept various modes of payments such as VISA, American Express, PayPal and other. Yatra.com website is almost similar in nature with makemytrip.com. I have also seen some advertisements which I believe those are Cost Per Click based. In addition, they also make money from flight bookings, hotels, trains, and other deals.
