Okay, I probably put way too much thought into this. But I found an old chatroom where a pilot burned 3361 gallons of fuel flying DFW to SEA, a 3 hour and 48 minute flight. 3361gallons/3.8hours = 885 gallons per hour. — According to https://www.airnav.com/fuel/report.html, JetA is currently selling for an average of $5.39 per gallon in the Great Lakes region. So an hour and a half movie would cost around $7,150.
