Genius is Booking.com's free loyalty programme.
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 3 levels. To progress to Level 2 in Genius, you need to complete 5 bookings within 2 years. To progress to Genius Level 3, you need to complete 15 bookings within 2 years. Each level comes with new rewards and bigger discounts.
All of the stay, flight, rental car, taxi, and attraction bookings you complete will count towards 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.
