Within 30 miles of LA all you have are poker cardrooms and a couple of horse tracks. The poker cardrooms offer a b*ized form of "blackjack," but don't bother.
Drive about 80 miles and you will encounter Indian casinos, they have blackjack and maybe even double-deck blackjack, but I have rarely had any luck there. As far as I know there is no gaming authority that will keep them honest as far as having to put all the 10-cards back in the deck.
Vegas is an hour and $100 away from LAX, BUR, SNA and ONT on WN; LGB on B6; LAX is also served by a very few AA and US flights.
One of the Indian casinos is called Moron go.
