Yes, Uber operates 24 hours a day, 7 days a week in Boston, Massachusetts. As a major metropolitan hub and home to Logan International Airport (BOS), there is a constant demand for transportation at all hours. To ensure high fulfillment rates during late-night hours or in less populated areas, Uber has integrated a partnership with local taxi fleets; if an UberX driver is unavailable, you may be matched with a licensed Boston taxi driver for the same UberX price. While the service is available around the clock, wait times can fluctuate depending on the time and location—demand peaks during "bar close" around 2:00 AM on weekends and for early morning airport runs between 4:00 AM and 6:00 AM. For critical journeys, such as catching a flight, Uber offers the "Reserve" feature, allowing you to schedule a ride up to 90 days in advance, providing peace of mind that a driver will be dispatched for your specific early-morning or late-night departure.
