There are two types of Non-revenue passengers:
- Positive Space. These are airline employees that have an actual seat on the plane traveling on business. There are also two types – “must ride” which are flight crew which are needed in another city or else a flight will cancel and mechanics being sent out to work on a plane at another airport to get it back in service or regular positive space, which are crew “deadheading” home to their base after working or non flightcrew employees traveling on business. “Must ride” Positive space cannot be denied boarding under any circumstances, however, non “must ride” positive space passengers are supposed to be bumped before any revenue passengers are involuntarily bumped. However, they WILL take volunteers in order to accommodate non-”must ride” positive space passengers.
- Space Available/Standby – these passengers are only given seats if there are empty seats available after all revenue passengers and positive space non-revenue passengers have been accommodated. These are usually employees, their family, and their friends traveling for leisure. It is very hard to get on popular flights flying Space Available.
