In reply to bigbobbyking:
I have been working on the new terminal 2a since 2010, so know all the in & outs.
Best place is T1 drop off up the ramp after the tunnel, it's obvious. As you go up the ramp keep left and your laughing. It's not as busy there either. My wife has picked me up from there several times in our Cali so don't suspect you have any worries.
Getting to the other terminals , even t5/4 via the underground is super easy from T1
Hope this helps
