This question already has an answer here:
I'm a Venezuelan citizen and am taking a long flight from Venezuela to Australia. I'm taking two connections and changing airplane two times; my schedule is: Venezuela-Mexico; Mexico-L.A., L.A-Sydney. In L.A. the layover is approximately seven and a half hours long during the afternoon; I arrive at 2 and depart at 10 approximately. So I was thinking if it's possible to get out of the airport, and do some shopping or even going for dinner... I don't really know if I need a visa for this or which type should it be?
Also I don't have any idea if the airport offers some type of luggage lockers or a luggage facility? From L.A. to Sydney I'm traveling by Qantas, in First Class. Is there anyone who knows if Qantas offers some type of luggage keeping service?
Sorry for the length I'll appreciate any info, or help. Thanks. I might sound like a newbie, but i don't even know if it's enough time for going downtown and then going back to airport...
I just don't want to expend 7 hours alone in the airport.
