Genius is Booking.com's free loyalty program.
To unlock Genius Level 1 and 10% discounts on select stays and rental cars, all you need to do is create a free Booking.com account.
Genius has three levels. To progress to Level 2 in Genius, you need to complete five bookings within two years. To progress to Genius Level 3, you need to complete 15 bookings within two years. Each level comes with new rewards and bigger discounts.
All the stay, flight, rental car, taxi, and attraction bookings you complete will count toward your progress in Genius. Before completed bookings show up in your progress, they need to be updated in our system, which can take some time.
