Yes — Delta Air Lines can cancel flights. Airlines may cancel a scheduled flight for a variety of reasons (e.g., aircraft issues, crew availability, weather or air-traffic control constraints). When Delta cancels, passengers are generally offered re-routing or a refund for unused portions of their ticket.
If you tell me the flight number or route, I can check whether yours specifically has been cancelled or changed.
