There are many options in rail and bus combinations. All of which start by taking Metrolink to Union Station where you can transfer to either the LAX Flyaway bus or the LA Metro Rail system (bearing in mind that the blue line is currently undergoing rehabilitation). All transfers would be fully ADA compliant via platform-level boarding on trains and wheelchair lift/ramp on buses.
With proper planning ahead your travel should be smooth sailing. Depending on the time that you need to arrive at LAX you can take any Metrolink Train from San Bernardino to L.A. Union Station. From L.A. Union Station, you can travel to LAX with several options.. 1)... LAX Flyaway Bus will give you the most direct travel to LAX with buses running every 30 minutes. 2)... Due to the current service interruptions with the ongoing upgrades on the Metro Blue Line, I highly recommend taking the LAX Flyaway Bus otherwise your travel to LAX from L.A. Union Station using the Metro Rails or Metro Buses may delay your arrival to LAX due to multiple connections. Happy & Safe Travels.
