My question is for EWR. Inbound to EWR on UA arriving at ~7:10a and then my outbound flight is at 9:20a Is it humanly possible to scoot off the flight assuming it's on time/early (sans baggage and carryons) to get out of security, have a smoke or four and get back in thru security and to the gate for the 9:20a flight. I have PreCheck and I'm traveling in F if that matters at all with timing/making it. Cause from 5:30a EST to 4:30p HST (which is 9:30p EST) is a hell of a long ride...
