Hi @Nicole3062
It appears that you can offer a friends & family discount on Airbnb by creating a custom discount link or using the special offer feature but not the usual (guest add promo codes on the Airbnb booking page):
Custom Promo Links: Airbnb allows you to create a custom promotional link that offers a specific discount for friends and family. You can set up this link directly from your hosting dashboard under the "Promotions" tab. This link can be shared with anyone, and when they use it to book your listing, the discount is automatically applied. Please see article: https://www.airbnb.com/help/article/2982
Special Offers: If someone is interested in your listing but hasn't booked yet, you can send them a special offer. This can be done through the message thread with the potential guest. You can specify a custom price that reflects the discount you wish to give them. Please see article: https://www.airbnb.com/help/article/35
Both methods let you control how much discount you want to provide, and they are great ways to manage bookings from people you know.
I hope this helps!
All the best,
Upfish Management
