Somehow the fact that the Central Valley is home to 6 million people -- roughly the same as the Bay Area -- continues to be lost in HSR conversations.
It has been LAWA's (LAX controlling authority) dream to build an international airport in Palmdale since the 1960s. They own over 17,000 acres of land out there, which combined with the 6,000 acres of land already used by Palmdale regional could fit six and a half LAX sized airports to become the single largest airport on the planet. All in a region that wouldn't just not constantly complain about the noise and threaten to sue over every airfield improvement, but would actively seek to promote this as a way to economic prosperity. And yet over the past 50 years they've utterly failed at convincing anyone to drive that far for a flight, even after spending millions subsidizing airlines to offer rock bottom prices in an effort to lure people away from the overcrowded LAX.

And now they'll be a high speed rail line to SF and the Central Valley running on the eastern border of the property, and a high speed rail line to Los Vegas running on the southern border, and at the corner of the property where they meet there will be a regional transit center and a high speed rail line going straight to DTLA. There's a ton of potential synergy between HSR and air travel.

This seems increasingly inevitable. By the year 2040, assuming air passenger growth trends stay constant (I actually expect them to grow on a percentage basis by more than they have been this decade), the Southern California region of airports (LAX/BUR/SNA/LGB/ONT/SAN) will have 342,549,779 passengers per year. Ambitiously assuming most of the intrastate/Vegas air passengers--or a passenger reduction of air travel by 7%--switch to HSR, Southern California will have 318,571,294 air passengers per year.
At the absolute maximum use, this requires eight runways of capacity, with room for future expansion. Bear in mind this means virtually every short haul flight being operated by an a321/b737 (~180 pax), mid-range flights being operated by an a350/b787 (~280 pax), and long haul flights being operated by an a380 (~500 pax). While all the Southern California Airports together have nine runways of capacity, only LAX's are useful for this level of operations. As such, a four runway airport will eventually be needed somewhere else.
The only two areas with this kind of space are in the Antelope Valley and at Camp Pendleton. The former would obviously be the more affordable and politically feasible option, with the added benefit of HSR connections to Burbank being ~15min, DTLA being ~25 min, and the Central Valley/Vegas being within the HSR catchment zone as well. Such an option would allow for the closure/redevelopment of increasingly useless BUR/LGB, but ONT/SNA/SAN should stay open for flights within their respective regions. In the longer run, and with future growth, perhaps by 2050, the latter will needed to be consolidated into a second four runway airport at Camp Pendleton. Ideally, the HSR alignment to San Diego should serve it.
Further on, LAX could be closed and redeveloped, with two more runways added at both Palmdale and Camp Pendleton, bringing them each to six runway megahubs. Future growth through the 2080s probably warrants one or two further runways at each.
