We are still anxiously awaiting the intra-terminal airside bus that CO stated they are going to start running...

However, in the meantime, making this connection involves leaving one terminal for another outside security, using the monorail. The time to allow for the connections depends on your status and the time of day.

Are you connecting inbound *from* BOS? If so, the later in the day your flight is scheduled to arrive EWR, the higher the possibility of ATC delays - far more stress inducing when you need to change terminals and reclear security.

I would make sure you have at least 60 minutes to make this connection for flights arriving EWR before 3pm, and at least 2.5 hours for flights scheduled to arrive EWR between 3pm and 7pm. If you are arriving EWR between 3p and 7p and your connection out of EWR is either international or the last flight of the day and you cannot risk a misconnect, I recommend at least 3 hours (right up to 4 hrs if possible)

Also, I recommend using the security checkpoint at the far end of T-C, at the 13x gates. When going downstairs from the monorail platform, go back up to the ticketing concourse, then walk to the end of the terminal, and back down to the gate level - this checkpoint is usually far less crowded than the ones at the 10x and 7x/9x gates. If the ID checker gives you a hassle about using a checkpoint away from your gate assignment, either tell him/her to bugger-off or state you are using the Presidents Club right outside the checkpoint.
