I have another LIMA connection question, but going the opposite direction from most other posters here - CUZ-LIM-EWR on a single LA+UA ticket.
United sells connections as short as 90 mins in LIM, although I'm looking at 2:05 on my itinerary. I don't think I need to collect/recheck bags, nor do I need to check-in again. But may need the special USA-bound flight security. Is this all correct? Is 2h enough? If I have to go through some of these formalities, I may just go carryon-only. Thank you.
You will need to go through LIM exit procedures (departure passport control and security) and then will have a gate security check after your zone has been called for boarding.
