📱 Booking.com spent $2.1 billion on marketing in Q1, a 16% increase from last year. Expedia and Booking.com together spent nearly $4 billion in a single quarter. Although AI tools like ChatGPT, Claude, and Gemini reduce options from 150 hotels to 5 instantly, guests still use Google, maps, and booking channels. The focus has shifted from choosing hotels to choosing booking platforms, with the battle for bookings intensifying rather than disappearing.
