How to pick-up and drop-off at Newark Airport's Terminal C (United Airlines, EWR)

If you are picking up from Terminal C, you contact the passenger and tell them to meet you on Level 2, Door 6. Next you enter Terminal B, Level 2 (not Level 1 or Level 3) and then drive through. Once you are past Terminal B, Terminal C ramp is ahead. Veer left onto Level 2 ramp. Door 6 is important because there is usually plenty of room to stop and park.
When dropping off, you enter Terminal B, Level 2 (not Level 1 or Level 3) and then drive through. Once you are past Terminal B, Terminal C ramp is ahead for drop-offs.
I strongly suggest not to utilize Terminal C Level 1 for pickups as it is frequently jammed and will take you at least 20 minutes to enter. I strongly suggest not to enter Level 2 or 3 through the traditional way of going through the circle or you will encounter strong traffic.
Always advise the passenger you are cutting through Terminal B to Terminal C.
When dropping off in Premier Access, always drop at the middle door or Door 2 as that is where the TSA Pre-Check area is located and there is construction constantly going on at Door 1.
Also remember, there are two ways to enter Terminal A. Through the front door traditional route or the back door. To utilize the back door you go past the 7-11 moving towards the Terminals. So you are on the other side of the highway. Keep going straight and you will enter an area that looks like it should be for authorized vehicles only. There will be taxis to the left of you when you enter this area. Keep going and eventually you get to the backdoor of Terminal A arrivals Door 1. Now if you go through that area you will end up in Terminal B Level 2 and that leads to Terminal C Level 2&3.
