What does overbooked mean?
Overbooked means that a service, venue, event, or schedule has accepted more bookings than it can accommodate. The word is especially common for flights, hotels, trains, conferences, and appointments. An overbooked flight may have more passengers than available seats, while an overbooked hotel may have reservations exceeding its room capacity. For people, overbooked can mean that their calendar is so full that no further appointments can be added. The expression developed from the ordinary meaning of booking a place and adding the prefix over-, which indicates excess or more than a normal amount. It is useful because it identifies a mismatch between recorded commitments and practical capacity. In everyday discussion, the term can also suggest overcrowding, inconvenience, or the likelihood that someone will be turned away, although businesses may occasionally handle the situation with alternatives such as refunds, compensation, or nearby accommodation.
adjectiveHaving more bookings, reservations, or appointments than can be accommodated. It can also describe a person whose schedule is completely filled.
- Having more reservations or bookings than the available capacity can accommodate.
- Having every available time, place, or opportunity committed, leaving no room for additional bookings.

Airlines sometimes sell more tickets than they have seats, counting on a few passengers not turning up—and sometimes overbooking turns into a crisis.

Etymology of overbooked
The word combines the prefix over- with the verb book, meaning to reserve a place. Its early modern ancestry is the established English sense of booking or arranging a reservation, which developed in contexts such as theatre seats and travel. The prefixed form overbooked emerged in the 20th century, initially in commercial and transport settings where reservations exceeded capacity. Related forms include booking, bookable, unbook, and overbooking, all reflecting the same long-standing vocabulary of making and managing reservations.
