In car rental, out of hours (OOH) refers to a service that some suppliers offer for vehicle collection. This means the supplier allows you to collect your rental car at a time outside their regular business hours, for example late at night or early in the morning.
The supplier may also charge a fee for this service, known as an out of hours fee.

Example sentence(s):
- The Out of Hours service is only available at airports.
- If the pick-up time is delayed out of the supplier's regular working hours, an Out of Hours fee applies.
- We will not charge the Out of Hours fee if you arrive 30 minutes or less after our closing time.
