You can’t apply a coupon after you book: Even if you contact Airbnb Support, we can’t apply a current or expired coupon after you’ve booked a reservation (future or past).
If you cancel, coupons are not refundable: Refunds are based on the host’s cancellation policy, and we can’t restore or reissue a coupon you redeemed in the past.
Expiration dates can’t be adjusted: Once a coupon has expired, it’s not possible to extend the expiration date or to get a replacement coupon. Expired coupons can't be used toward past reservations.
Limit one coupon per reservation: It’s not possible to apply multiple coupons to a reservation.
Tip: You may be able to check your coupon amount and the expiration date on the payments page in your account.
