✈️ Flight Guide: San Francisco (SFO) → Salt Lake City (SLC)

December cultural highlights along the SFO–SLC corridor include holiday festivities in San Francisco and ski-season opening events around Salt Lake City. In San Francisco, Union Square holiday lights, the Embarcadero's Bay Area winter displays, and the San Francisco Ballet's Nutcracker draw visitors. In Salt Lake City and nearby Park City, December features Temple Square Christmas lights, opening-week events at local ski resorts, seasonal concerts, and New Year's celebrations. These events drive increased December air travel and should inform flight and hotel bookings.

The best time to fly SFO to SLC in December for lower fares and fewer delays is early December on weekdays (Tuesday–Thursday) and early-morning flights. Avoid peak holiday windows from about December 20–27 when prices and crowds surge. For ski trips, midweek stays often reduce both airfare and lodging costs. If you need maximum flexibility, choose refundable or changeable fares and consider flying into alternative airports like Oakland (OAK) or San Jose (SJC) for last-minute savings.

Direct (nonstop) SFO to SLC flights are generally preferable in December for shorter travel time and fewer weather-related connection risks, with typical nonstop durations under two hours. Connecting flights via hubs like Denver (DEN), Salt Lake City (if continuing), or Phoenix (PHX) can sometimes offer lower fares or more flexible timing but add risk of missed connections during winter storms. If you prioritize speed and minimizing weather exposure, book nonstop flights and choose morning departures; if price is the priority, a connecting itinerary with a generous layover might save money.

Compare major carriers flying SFO to SLC in December: Delta Air Lines offers robust schedules and Medallion benefits; United Airlines provides strong network connectivity and Premier perks; Alaska Airlines often has competitive fares and loyalty partners; Southwest Airlines offers free checked bags and flexible change policies. On-time performance varies with winter weather, so review each carrier's winter operations. Consider baggage fees, change/cancellation policies, loyalty program benefits, and included amenities when choosing an airline for December travel.

Traveling from San Francisco International Airport (SFO) to Salt Lake City International Airport (SLC) in December requires winter preparedness. Pack layered clothing, waterproof boots, and essentials like medications and chargers in your carry-on. For ski trips, reserve shuttle transfers or rent vehicles with snow tires or chains; verify airlines' ski and snowboard baggage policies in advance. Allow longer connection times, enroll in TSA PreCheck to speed security, and purchase travel protection for weather-related cancellations. Check both SFO and SLC airport advisories the morning of travel and keep airline app notifications enabled.

Nonstop flights between San Francisco International Airport (SFO) and Salt Lake City International Airport (SLC) usually take about 1 hour 45 minutes to 2 hours. In December, airlines may add flights on weekends and peak holiday dates to serve ski and holiday travelers; expect early-morning departures and evening returns. Major carriers offering frequent schedules include Delta Air Lines, United Airlines, Alaska Airlines, and Southwest Airlines. For best on-time performance in winter, choose morning flights and monitor both SFO and SLC airport status boards for delays.

Find cheap flights from San Francisco International Airport (SFO) to Salt Lake City International Airport (SLC) in December by booking 4–8 weeks ahead, targeting midweek departures, and setting fare alerts.

Student and military discounts may apply; sign up for airline newsletters and use low-cost carriers to find competitive December deals.
