Travel Tips
To maximize your comfort on the cross-country journey from Michigan to California, consider booking a seat on the left side of the aircraft for potential views of the Coronado Bridge and the stunning downtown skyline upon arrival. Since the flight duration is significant, bring a light jacket or multiple layers, as cabin temperatures fluctuate and San Diego’s evening coastal breeze can be surprisingly cool despite the daytime heat. We recommend downloading your airline's mobile app ahead of time to track gate changes at DTW’s expansive McNamara or Evans terminals. Finally, remember that San Diego is three hours behind Detroit, so stay well-hydrated and try to adjust your sleep schedule a day early to minimize the effects of jet lag once you land.

San Diego International Airport (SAN) is uniquely situated just minutes away from the downtown core, offering one of the most scenic and urban landing approaches in the United States. As a single-runway airport, it is remarkably efficient, housing two main terminals that provide easy access to ground transportation, including the free San Diego Flyer shuttle to the Old Town transit center. Its proximity to the harbor means you can transition from the baggage claim to a waterfront dinner in less than fifteen minutes after leaving the terminal.

The cheapest fares are often found during the late winter months of January and February, excluding holiday periods, when the crowds are thinner and the Michigan cold is at its peak.
