However, we can make an approximation based on typical fuel consumption rates for commercial passenger aircraft.
The Boeing 737-800, a commonly used aircraft on this route, has a maximum fuel capacity of approximately 6,875 US gallons (26,018 liters). On a flight from SYR to SLC, which covers a distance of around 1,644 miles (2,646 kilometers), the aircraft would likely require around 3,000-3,500 US gallons (11,356-13,247 liters) of jet fuel, assuming a cruise altitude of around 35,000 feet and favorable weather conditions.
This fuel estimate includes reserves and extra fuel required for taxiing, takeoff, climb, descent, and landing. It's worth noting that these figures are rough estimates and actual fuel consumption can vary depending on specific flight conditions and operational procedures.
