Help! I must be old but I am still confused. we are travelling from Brisbane to LA with a 3 hour layover then onto LV. all with Qantas and they said our luggage will be checked through to LV. do we go through immigration and customs in LA or LV. I am wanting to book a Limo rather than get one outside the airport but after hearing about them charging extra for wait time of international visitors thought I had better ask. so will our flight from LA be a domestic flight and we would have already cleared immigration, so we will only need to get our bags?
