I have an 8 pm flight out of Lisbon. I will be touring the city before the flight. Does afternoon rush hour go in the direction toward the airport? What time should I leave the city center? Am I better off taking a pre-arranged cab or the metro? Thanks in advance!
One more question - for a different trip to Lisbon - If my flight arrives at 4:55 p.m. and I have no baggage, is it possible to be in the city center by 6:30 p.m? Is a pre-arranged cab or metro faster at that time?
