That being said, turboprop planes travel at various speeds depending on altitude, weather, and specific aircraft characteristics. Their typical cruising speed can be anywhere between 250 to 350 miles per hour (402 to 563 kilometers per hour). Considering this speed range and adding time for climb, descent, and stops, the flight from Los Angeles to New York on a turboprop plane could take anywhere from roughly 10 hours to 15 hours. This is significantly slower compared to commercial jet aircraft, which usually make this trip in around 5 to 6 hours of flight time.
