I have a booking for 5, 2 of us are Gold, actually maybe 3. We have a tightish connection at LAX (2 hours) in which time we have to go through passport control (Non US citizens) and connect flights. Will we be allowed through the 1st class line at LAX for security? If not, can we usually speak to the people on the line if we're running late for the connection (I know this worked at JFK last month for a different carrier).

Thanks in advance
