I always laughed...yes every college intern can calculate how much it cost to carry an extra ton of fuel per said flight...it’s on the flight plan. But they never mention how much it cost when a flight has to divert, and possibly the crew will exceed their max duty and passengers have to be accommodated etc... and this isn’t even considering the safety of the flight as cnn so accurately reported “ the 777 struggles to maintain altitude once the fuel tanks are empty”
