Similar question and I suppose the answer is similar, but I just wanted to check...
EWR-LIS-ACC. Arriving 8:20am on United, Departing 9:45am on TAP. All Terminal 1. In C, so I'd be fast to get off the plane (though probably just onto a bus to the terminal). Hand luggage only.
Two questions.
1. Would I be correct to assume it's straightforwardly & easy unless United is seriously late.
2. Would I be correct to assume that there's no need to deal with immigration, just clearing security?
