I scheduled an Uber pick up for 3 am in north Scottsdale Az for a 5:15 am plane. Uber did nothing to assure there would be a driver available at that hour. Uber simply began searching for a driver at 3 am. As a result I was forced to wake my son to take me to the airport. This is not a scheduled car service. It is unreliable. I will make other arrangements in the future. Thedaler
