Looking at the flight record for that date this flight departed KSFO for KPSP at 4:49 on 12/30. The track shows it about halfway to LAX when it reverses course and returns to KSFO. It departs again at 5:43 and then lands at KPSP at 6:55.
Wondering if it returned to SFO or if this was a hiccup in the flight recording.
Total flight time as 2H 22M on a usual 1H 24Mleg.
