Ticket reservation is the process of booking a seat or entry for an event, such as a concert, movie, or flight. This can be done online, over the phone, or in person at a box office. Customers typically select their desired date, time, and location, and then pay for the tickets to secure their spot. Once the reservation is confirmed, customers receive a confirmation number or electronic ticket, which they may need to present at the venue. This system helps manage attendance and ensures that people have a guaranteed place at the event they wish to attend.
