I am thinking about flying from Porto to Lisbon. My flight from Porto gets in @ 8:35AM & flight to the US, leaves @ 10:35 AM my question is do I have to go through security again, TSA etc after I collect my baggage, will I have enough time between flights because of the flight from Porto being domestic & the US flight International. Do they both arrive & leave the same terminal. Just need to know before making reservations.
That is plenty of time. If both flights are on the same reservation you don't have to do anything with your baggage or go through security. All TAP flights are in Terminal 1, both domestic and international. You will just go through Schengen exit passport control in Lisbon which is a very brief process.
Both flights are not on same reservation. I will be flying in from Porto on Portugal Air, collecting my bag & then flying to US with AA. So I'm assuming I have to check in with AA & then go through security. I have a global security clearance so I'm also assuming that will be quicker.
