Hawaiian 33 routing question

Wed Jul 06, 2022 4:27 pm

Just curious if anyone know what's going on with HAL 33? Usually, Hawaiian 33 (my favorite flight to Maui) heads out over the Pacific pretty straight from LAX - OGG, but today it seems to have flown northerly up the California coast and finally turned west just north of Monterey. None of the other Hawaii bound flights out of LAX that I've been watching have done this so I'm curious about this routing.

Any ideas or informed speculation?

Mods, apologies if this is the wrong forum.

Take care all,

Bob

Hawaiian 71 out of LGB is doing the same thing. I have seen this before but do not know the exact reasoning. I suspect it is due to congestion on certain tracks.

If you look at FR24, you can see that all flights heading toward Hawaii are heading either well south or north off the California coast (essentially a big empty gap due west of LAX)...could be a number of things. Military activity out over the Pacific or wind related would be my guess. Happens every so often

There's an Airmet Sierra from the southern Californian border all the way up through Oregon with CIG BLW 010/VIS BLW 3SM, but I don't see why that's such a big deal.

I see this all the time with the routing up the coast and then a swing a left to the islands and it'll be interesting to know why certain flights have this routing.

Remember that the California coast pretty heavily points west going up to around San Luis Obispo, and still keeps going after. So taking advantage of winds by going a bit North isn't going all that far out of the way.

If you look on the Windy app at the 250mb level (app. f340) there’s significantly less wind on that more northerly track. Take off 30kt of headwind for 3 hours, it’s a good savings in time and fuel.

I had no idea that app displayed winds aloft (in 50mb increments it seems). That app has a good UI too. Thanks.

Thank you for all of the replies. I used to fairly regularly fly LAX-OGG and never flew this routing, nor have I ever seen it before. Great info, thank you all.

As others have mentioned, it’s all dependent on the winds which is done to save time, thus saving fuel and ultimately money.
