How far is San Diego from San Antonio? Here's the quick answer if you have friends taking shifts as driver so that you can make the entire trip by car without stopping.
Nonstop drive: 1,275 miles or 2052 km
Driving time: 18 hours, 1 minute
This is a really long drive, so it's not very realistic to drive nonstop. To get a better idea of how long this road trip would actually take, scroll down to calculate how many hours it would be if you drive with stops.
Now let's assume you have a private jet and you can fly in the fastest possible straight line between San Antonio, Texas and San Diego, California. Because of the curvature of the Earth, the shortest distance is actually the "great circle" distance, or "as the crow flies" which is calculated using an iterative Vincenty formula. For a long distance, this appears as a curve on the map, and this is often the route that commercial airlines will take so it's a good estimate of the frequent flyer miles you'll accumulate as well.
Flight distance: 1,128 miles or 1816 km
Flight time: 2 hours, 37 minutes
The straight line flight distance is 147 miles less than driving on roads, which means the driving distance is roughly 1.1x of the flight distance.
Your plane flies much faster than a car, so the flight time is about 1/6th of the time it would take to drive.
This is a medium length flight, so unless you have a nice private jet, you might be booking a commercial flight. In that case, your travel time would really need to include how many minutes to get to your local airport, wait for security, board and taxi on the runway, land at the other airport, and get to your destination. Scroll down to see a more realistic calculation that takes into account all these factors to get a more accurate estimate of your actual flight time.

In the quick calculation above, we assumed you had a private plane and just wanted to know the time in the air from city to city. But for most of us, we're going to be flying on a commercial airline (whether it's first class or coach). So that means we really need to account for all the extra travel time getting to the airport, waiting for our flight, and making it to the destination.
To give you a better estimate of real-life travel, we've put together a flight itinerary with actual airports. Eventually you'll be able to customize this plan, choosing your own airports and flights. But for now, here's an example we've selected to give you an idea of how traveling might work between airports.
Departure airport: San Antonio International Airport (SAT)
Arrival airport: San Diego International Airport (SAN)
With the airports selected, we can estimate the travel time to and from the airport, based on how far the airport is from downtown.
Getting to the airport: 22 minutes
Getting to your destination: 7 minutes
Now finally, let's look at an actual flight from SAT connecting through TPA and arriving at SAN flying on Southwest Airlines. We can figure out how long it would take to fly including take-off and landing, time to taxi on the runways, and an average layover time of about 2 hours.
Initial flight time: 2 hours, 17 minutes
Connecting airport: Tampa International Airport (TPA)
Connection flight time: 4 hours, 40 minutes
So now we can finally get an idea of the total travel time from San Antonio to San Diego including time spent getting to and from the airports, roughly 2 hours at the departure airport for TSA security lines and waiting at the gate, plus the connecting flight with a 2-hour layover.
Total travel time: 11 hours
