How We Calculated
For each trip we assumed a round trip. For transportation we used $0.535 per mile as specified by the IRS for the cost of gas, insurance, wear and tear to your vehicle. Taxis, vans, private transportation would likely cost more. Parking is calculated using the information provided by the respective airports in their long-term lots. Trips to OAK airport incur a $5 bridge toll charge and trips to SFO incur a $6.50 bridge toll. Travel time estimations were provided by Google Maps at the time of publishing and are calculated using Monday at 11 a.m. at the planned travel time. If your flight is at a different time, traffic could be much more of a factor.
At lot of time is spent after you arrive at the airport parking lot until you arrive at the boarding gate. It begins by finding a parking space and getting to the terminal. In some airports this includes finding the parking lot shuttle or tram, waiting for it to arrive and the subsequent travel to your terminal, which may not be the first stop. It also includes the time required to check luggage and to pass through security, which can be highly variable depending on the time of day and day of week. It also includes the amount of time it takes to walk to your gate (SFO terminal 3 is nearly 1/3 mile long!). When you return back to your home airport you will need to walk to baggage, find the right carousel and wait for your bag to appear. Then you’ll have to walk to the shuttle or tram and wait for it to arrive and take you back to your parking lot where you can find your car.
