While LGB does have the catchment of South Bay, Long Beach, portions of OC, that’s pretty much it and they are right in between and have to share that with LAX and SNA.
BUR caters to a far broader demographic. Bakersfield, Palmdale, Lancaster, Santa Clarita Valley, Simi Valley, Ventura and surrounding communities, the entire San Fernando Valley, westdide LA , Hollywood, Downtown LA, La Creacenta Valley, Glendale, and Pasadena. A far larger catchment than LGB so I’m going to kindly disagree with you.
You are not disagreeing with me, you are disagreeing with reality.
Even BUR airport in its new terminal EIR says its catchment area only represents 17.7 percent of regions domestic O&D demand. (LGB was 43 percent).
Also the airports Part-161(noise/curfew) study says the airport maximum theoretical level of activity is 7.3mil annual passengers (airport peaked at 5.9mil in 2007), which is under 5 percent of the regions overall forecast traffic demand per the Southern California Association of Governments 2025 traffic forecast.
So the reality is that being tucked away in the Northern half of basin far reduces the airport's catchment area when compared to much more central airport like LGB.
Yes sure BUR has demand, but its nothing more than a community airport that can serve its niche, not one with broad regional appeal.
