I have a Qantas flight Lax to Sydney on 31 st August departing at 10.30pm. I need to book a domestic flight from Las Vegas to Lax on 31 st August. I'll be booking the domestic flight with Delta or American. I would like tto know how much time I will need to pick up my bags and checkin in st the tom Bradley international terminal and clear security? Is 2 hours and 15 minutes enough or would I need at least 3 hours.?
