Hey guys, I made a spreadsheet calculating the per seat airplane cost.
The per seat airplane cost is calculated by dividng the airplane purchase price with the maximum amount of seats listed. The per seat airplane cost relation is the same if the calculations were carried out using the monthly lease instead of the purchase price, because the monthly lease is 1/90th of the purchase price.
