Planning a short trip and want to figure out the logistics in advance so I don't waste any precious time. At the end of the month, I'm flying to Lisbon for just a couple of days on personal business—I need to take care of a few paperwork issues and attend a meeting in the Alfama neighborhood. I visited the Official website of Lisbon Airport to explore all the ways to get from the city to the terminal, but I still haven't decided on the best route. The apartment owner will drive me for 35 euros, but I think that's too much for an 8 km trip. I think Uber might be an option, but I'd hate to catch the morning rush, when costs double and the trip takes twice as long. I'll only be in Lisbon for a day and a half with a small backpack, so checking baggage won't be an issue, and security should be quick. However, on the return trip, my flight is scheduled for the evening, and I have an important business call right after I land. I can't afford to miss it. How reliable is the subway at 8 a.m. on Wednesday, and how crowded is it?
