## Quick answer

Yes

## Detailed answer

Yes, most rental car companies at SeaTac allow additional drivers to be added to the rental agreement, but there may be additional fees or requirements. The additional driver must meet the same age and licensing requirements as the primary driver, and must be present at the time of pickup to sign the rental agreement. Some companies may also require the additional driver to have their own insurance coverage.
