Airbnb offers guests the option to specify a specific check-in window to let hosts know a more accurate time that the guests are planning to arrive. When guests choose to specify a check-in window, these values override the Latest Check-In Time value on the booking. So if my property is set to allow a Check-In Time up until 11 pm, but the guest says that they will be arriving between 4 pm and 6 pm, my Latest Check-In Time value gets overridden to 6 pm. This is problematic because my guest arrival information uses the {BCHECKINTIME} field code and it tells the guest that my check-in window is now 4 pm to 6 pm, which is incorrect. It makes the guest think that they now have to arrive by 6 pm, even though they have until 11 pm. The Latest Check-In Time value for a booking or property should never be overridden by guest-provided values from Airbnb. If OwnerRez would like to display the guest-provided estimated arrival window times, these values should be stored in a separate data field and not impact the {BCHECKINTIME} field code or the Latest Check-In Time value for a booking or property.
