We are Located at General Aviation side of Key West International Airport.

Driving Directions: Drive US1 south to the point where US1 meets Key West. The Highway splits. A right would take you towards downtown Key West. Left takes you to the beaches. Take the left turn, it is signposted A1A (S. Roosevelt Blvd). Keep straight for 1.3 miles. Turn right into the main entrance of Key West Int'l Airport. At the first stop sign stay on the ground level towards arrivals. Drive under two walkways. As you drive under the second walkway get in the right lane and drive straight on past the control tower. Just beyond the control tower is our FREE PARKING, the lot is signed parking for Signature Aviation. You will need a parking permit which is given to you at check in. Our office & check in is right off this lot. Do not park in the spaces marked FAA.
