All of San Antonio International Airport — runways, frequencies, charts and live weather

Before taxi San Antonio

ATIS 118.9: A recorded loop of the field's weather, active runway and any notices, updated hourly or whenever conditions change. Listen before your first call, and tell the controller which letter you have so they do not read it to you again.
Clearance 126.7: Clearance delivery issues your IFR clearance, and at busier fields your VFR departure instructions and squawk code. Call before you request taxi, with the ATIS letter and your intended direction of flight.

Taxi & takeoff San Antonio

Ground 121.9: Ground control owns every taxiway and inactive runway on the field. Call for taxi with your position and destination on the field. You need an explicit clearance to cross any runway, including one that is not in use.
Tower 119.8: Tower owns the active runways and the surrounding surface area. Call before entering the surface area inbound, and hold short until you are cleared to take off or to cross.

Emergency 121.5: 121.5 is the international emergency and distress frequency, monitored continuously. Declare on it if you are in trouble, and monitor it as a second radio when you have one free.
