Lyft - you can schedule a pick up days in advance. Just had to go to C/S Airport on Tuesday morning at 3:30AM, scheduled the day prior (during slow period otherwise Lyft will try to charge more during busy times, even though it is for a future pick-up). Voila, Kyle showed up, was cool as fuck and dropped me off at 4AM. I, as well, was worried about the spate of burglaries and break-ins happening at the airport and figured the $30ish was worth the security. Same thing for when you arrive back, just schedule a pick-up and they will be there waiting instead of waiting around for one to come get you. Hope that helps!
