An arrangement to have tickets, a hotel room, etc. at a particular time in
the future that you make some time before you go, or the process of making
this arrangement. Booking systems can automate many tasks and functions that
would otherwise take a lot of time and effort, such as searching for the best
options, sending booking confirmations, generating invoices and receipts, updating
calendars and itineraries, sending reminders and alerts, and syncing with
other systems.
