Nonstops to both
SAT sits about 8 miles north of downtown and flies nonstop to both cities. Southwest covers Phoenix and Atlanta, Delta adds Atlanta.
VIA Route 5 runs airport to downtown every day, about 30 minutes. Board at the far west end of Terminal B, lower roadway.
Phoenix is Sky Harbor, a Southwest and American hub. There is no light rail into Scottsdale, so plan a ride from the airport.
Atlanta is Hartsfield-Jackson. MARTA rail runs from the Domestic Terminal straight into downtown.
Driving is about 980 miles either way, most of two days on I-10 to Arizona. Book the flight.
February in Scottsdale, March in Atlanta
Scottsdale in February feels a lot like home. Highs near 71 against San Antonio's 67, nights near 49 against 45, about half the rain. Bring layers for the cool desert mornings.
February also brings the Phoenix Open to Scottsdale, so book your room early.
Atlanta in March runs highs in the mid 60s and nights in the mid 40s. About 8 degrees cooler than a San Antonio March, so pack a real jacket.
Tree pollen peaks in late March up there. If it sets you off, pack the allergy medicine. A blocked nose and a Breathwork training do not mix.
