I am developing plugins extending Woocommerce.
This plugins is for trip booking.
My objective is to get the customer information such as his arrival at airport and his next flight time, and show it during the checkout.
I know it can be added to the booking after checkout, but I need to show it somewhere before the checkout. Is there any Cart property i can use to store that information? I can't see anything suitable as per Class WC_Cart documentation.
