I'll be traveling on DL 1735 from KLAX to PHLI in the next few weeks. Looking at FlightAware for the flight's performance in the last 10 days, I've noticed it performing a zig-zag pattern before approaching the Hawaiian Island chain. This seems to be a daily occurrence. I've provided a link with the latest occurrence:
Does this pattern suggest that this would be some sort of ATC hold? I can imagine this happening every so often, but it seems to be happening day-over-day. Does anyone have insight into what could be the reason of this zig-zag pattern?
