You will arrive into Terminal D, but your flight will likely depart from A or C. You can realistically get anywhere within the airport in 20 minutes, so it will really depend on your flights actual arrival time and how long it takes to clear immigration/customs and security. I can go from gate to lounge in less than 30 minutes (probably less than 20) with global entry/precheck and a fast walking pace without checked bags.
Thanks - unfortunately it's just me with GE so probably it'll be only a quick drink next to the gate.
Is there similar to EWR a check in after customs or do we need to walk with the luggage to Terminals A or C (or can we check in at Terminal D)?
