I was drinking some not very good Shiraz last night up front - thinking about how much it costs to fly me. I'll do 160,000 miles this year on Co @ 6.5 cents a mile. Discounting the cost of the first class meal and the seat - both of which would have gone to waste without me there and budgeting the wine at $5 a bottle - say $1 worth for my share - the real cost is the additional fuel per mile per pound of me and my bags. I weigh 150lbs and carry not more than a briefcase and a change of clothes - say 10lbs. Let's assume the seat in coach would have flown emtpy if they had not sold me the ticket (a big assumption but it is one they make when the let me by U-tickets way out and presumably that is one thing they have sophisticated statisticans work on). (Let's assume I spend all the miles I earn (300,000) on coach fllights @ 50,000 each rt coast to coast for my family.) Assume I am on a newish 737-800. Based on current oil prices, how much do I cost per mile?
