I am flying overseas next weekend via Newark Airport with a short layover. My incoming flight arrives at Terminal C and my outgoing flight leaves from Terminal B. I have tried to get information from United Airlines, but I haven't had any luck. Is the airside shuttle bus at Newark Airport running right now?
When I went through EWR in late December I think it was running (not 100% sure), which was not a case maybe 6 months ago. Please note the shuttle only runs in the afternoon.
If there is no shuttle, you need to take the Airtrain which means you will have to go through security in Terminal B again. Having TSAPre would certainly help with that.
If this is a single ticket the airline has responsibility for making the connection possible. They know quite well how long the average connection: if it's too risky they wouldn't have sold you a ticket. If you miss it, they will rebook you on the next available flight.
If these are two separate tickets you are out of luck.
