I hope you didn't have to spend $100k to get to the airlines
. Our two year collegiate program for 0-CFII, tuition, books, checkrides, housing costs with a single room, etc, would still be under $100k.
I guess if you go to Embry Riddle or something similar you will spend $100,000+ when you include tuition and board, but to a certain extent the degree should be considered a separate investment from the pilot training.
