If you don't encounter any delays on arrival, I would consider the trip.
Thank you. Good to know. I might look into this option on my return flight to Canada when I have a 5 h 30 min layover in LIS. In that situation the question would be how long would it take me to go trough security for the flight from Lisbon to Toronto, i.e. how early should I be back at the airport for the international flight
