Unusual radar track for Horizons CRJ into KSBA.

[Ground Point 9er]

Just wondering what was the story behind tonights Horizon Airlines service into Santa Barbara from Sacramento California. The flight appears to have been airborne for about an hour past its normal flight time of 45mins and also made a series of 360 and 180 degree turns before the approach into KSBA. I noticed they had been held at FL210 for awhile according to the track log. Not saying there is anything extreme or news worthy about the situation. Just caught my eye and I was curious as the radar track for any other given day is more straight forward and direct. (See Flightaware radar track website link below for flight# QXE645 21st March 2010 KSMF to KSBA.)
