I have an upcoming flight and am trying to decide how to arrange transportation to the airport. My departure is fairly early, so I would rather have everything planned ahead instead of looking for a ride at the last minute. I will also have a suitcase with me, which makes changing trains less appealing. I am considering an airport taxi but would like to hear how other travelers handle this. Do you usually reserve your ride several days in advance, and how much time do you normally leave between your pickup and the scheduled flight?
