Booking refers to the process of reserving a service or accommodation in advance. This can include activities such as securing a flight, hotel room, or event ticket. The booking process typically involves selecting dates, providing personal information, and making a payment to confirm the reservation. In the travel industry, booking can be done through various platforms, including websites, mobile apps, or travel agencies. Customers often receive a confirmation email or message that includes details about their reservation, such as flight times, hotel addresses, and event dates. This ensures that the service will be available when needed.
