December in San Antonio centers on River Walk holiday lighting, seasonal markets at The Pearl, and home games for the San Antonio Spurs which boost arrivals at San Antonio International Airport (SAT). Popular events include the River Walk holiday illumination and downtown New Year’s celebrations. In Phoenix and surrounding cities (Scottsdale, Tempe, Mesa, Tucson), seasonal attractions like Phoenix ZooLights, Winterhaven Festival of Lights in Tucson, and holiday shopping events increase regional travel. If attending festivals or Spurs games, book flights and ground transport well in advance as December event nights generate higher demand for taxis and ride-share services.
The best time to fly PHX to SAT in December is generally the first two weeks of the month and midweek (Tuesdays and Wednesdays), when fares and airport crowds are lower. Early morning departures and late-night flights often have fewer delays and can be cheaper than peak afternoon times. Avoid peak holiday windows — typically the days immediately before and after Christmas and New Year’s — when prices surge and flights fill quickly. For the best deals, book at least 6–8 weeks in advance for Christmas travel and take advantage of flexible-date search tools and fare alerts.
For the short Phoenix (All Airports) (PHXA) to San Antonio International Airport (SAT) route, nonstop flights are generally recommended — they reduce total travel time to about 2 hours 10–30 minutes and minimize the risk of missed connections during December holiday travel. Connecting flights can offer lower fares or more flexible timing but add layovers (commonly in hubs like Dallas/Fort Worth or Phoenix for certain carriers) that increase total door-to-door time. If price is your highest priority and you have flexibility, consider one-stop itineraries; otherwise, choose direct flights to reduce travel stress during busy December windows.
Southwest Airlines often offers multiple nonstop options and competitive fares for travelers between Phoenix (All Airports) (PHXA) and San Antonio International Airport (SAT); its free two-checked-bag policy can save money for families.

Delta and United may offer connecting options via their hub airports and can be useful if loyalty status or alliance benefits matter. Compare fare classes, baggage allowances, and change/cancellation policies — especially for December holiday itineraries — to select the carrier that balances price, convenience, and loyalty perks. Book early during December to lock in desirable schedules and seats.
