Hi all,
I’m using Airtable as a reservations automation platform for my short-term rentals.
In 1 table (Bookings) i have all the bookings with their relevant information (check-in, check-out, # of guests, …etc). This table is linked to a second table called “Guests”, which summarises everything for this guest, including the booking this guest has made, unique phone numbers, unique emails, how much they’ve spent so far…etc
In the “Guests” table, i am trying to create a field which counts the number of unique reservations (based on check-in date), this guest has made.
I currently have the following set up in the “Guests” table:
Right now, the formula in “Returning guest” is showing “Returning” if the “# of reservations” field is larger than 1. This is not completely accurate because a guest can have multiple reservations on the same day but for multiple properties, which does not make him a Returning guest.
Ideally i would like to have the formula compare the number of dates in “All check-ins”, and “unique check-ins”, and if they are not the same, then i can show the guest as a “Returning Guest”.
The simple solution here would be to have a Count Unique formula, however as this does not exist, i’m trying to find another way to do this.
Would appreciate any and all help!
