Arriving in LAX Terminal B at 755pm, next flight on AS at Terminal 6 at 11.39pm, leaving me around 3h44mins transfer time if there are no delays.
It's not a single ticket, no check-through luggage. Don't have global entry, though I can apply for mobile passport as a Singaporean. Will have 1 checked bag, how safe/dangerous am I with catching my flight?

To clarify - I will need to go through customs at Terminal B, collect my baggage and then find my way to terminal 6 to check in.

Thanks in advance!
