Signature Flight Support

Signature Flight Support at Spirit of St. Louis was formerly TAC Air before joining the Signature Aviation network. The transition brought the location into the ELITE+ program, which extends tier-based benefits to frequent travelers across the full Signature system. The facility operates 24 hours a day, seven days a week.

For charter passengers, the ELITE+ membership works the same way here as at any other Signature location. Priority fueling, preferred parking, and consistent handling standards apply regardless of whether your last stop was a major hub or a smaller market like St. Louis. If you travel regularly across a mix of markets, having a single account that covers Signature locations simplifies billing and avoids re-establishing preferences at each FBO.

The business center includes conference rooms, private workrooms, and the workspace infrastructure that allows passengers to stay productive during a ground stop. If your trip involves meetings before a return leg, the on-site conference space gives you an option without leaving the airport environment.

Spirit of St. Louis sits 19 miles west of downtown, which means passengers heading into Clayton, Chesterfield, or the western suburbs reach their destinations faster than they would from Lambert. The location along the 40/64 corridor also gives access to the mid-county business parks that host a significant share of St. Louis corporate activity.

For aircraft operators who use Signature consistently, the network reliability at KSUS means ground coordination follows a predictable pattern. Fueling, parking, and passenger handling are handled through the same procedures and systems that apply at Signature facilities across the country.
