A domestic same-ticket connection can be very different from an international arrival or self-transfer. Identify whether you must clear immigration, collect bags or leave the secure area before estimating time.
Changing terminals
EWR’s official connection guide points travelers to AirTrain for many terminal changes. Terminal A has an added shuttle/walk step from its AirTrain station, and landside terminal changes normally mean security again.
Airside United shuttle
The airport describes limited United-operated airside shuttle routes between selected gates/terminal areas. These routes have operating hours and accessibility limitations, so do not assume your itinerary qualifies.
International arrivals
International arrivals without preclearance follow customs/immigration procedures. Depending on itinerary and baggage through-check, onward passengers may have to collect bags and re-enter security.
Separate tickets
With separate tickets, plan as if the first trip ends at EWR: collect bags if needed, reach the next terminal, check in again before the cutoff, and clear security.
