Here is the math, $100 to change my CO ticket, $69 for the flight on WN. Now, I will fly enough on CO to earn Plat for next year, no reason to pay the $100 to change this flight. Should have booked on WN to start with. Lesson hard learned, WN first, CO second, DL third. That is now the official pecking order for JRF in 2001. Thanks CO, I was looking forward to upgrades of at all fare levels.
