Lindsay Lohan -- Mom and Sister Leave Town

Hopefully, Lindsay Lohan is making a few friends inside her UCLA rehab facility -- because most of the people authorized to visit the actress have just left town.

Dina and Ali Lohan were spotted at LAX yesterday getting ready to get on a plane -- destination unknown.

As we previously reported, several people close to Lindsay have been told that LiLo will only be allowed to receive visits  from approved blood relatives for the first 30 days of treatment.

UPDATE: Turns out the Lohan gals were headed to NY to spend some time at home.
