Travel Tips
To maximize your comfort and savings on the BWI to SAN route, prioritize booking non-stop flights with Southwest Airlines, which maintains a significant hub at Baltimore and frequently offers direct service to San Diego. Given that the flight duration is roughly six hours, it is wise to pack essential electronics, high-quality noise-canceling headphones, and a portable power bank to stay entertained throughout the cross-country trek. Since you will be crossing three time zones, try to stay hydrated and adjust your watch to Pacific Time as soon as you board to help mitigate the effects of jet lag. Additionally, because San Diego's weather can vary between the coastal breeze and inland heat, wearing light layers will ensure you are comfortable the moment you step off the plane into the California air.
