Yes, as a host in 2026, you can absolutely decline an Airbnb booking request, but you must do so within the 24-hour window to maintain your "Response Rate," which is a key metric for becoming or remaining a Superhost. You are not required to accept every guest, especially if their profile has poor reviews, if they haven't shared their trip purpose, or if the request violates your "House Rules" (such as bringing pets to a non-pet-friendly home). However, Airbnb has a strict Nondiscrimination Policy; you cannot decline a guest based on race, religion, sexual orientation, or disability. If a host declines an unusually high percentage of requests, Airbnb's algorithm may lower their listing's visibility in search results or temporarily "snooze" the account, as the platform prioritizes reliable hosts who are likely to confirm bookings. If you find yourself declining often because of scheduling conflicts, Airbnb recommends using the "Instant Book" feature only for guests who meet specific credentials, or keeping your calendar more strictly updated to avoid unnecessary requests.
