Please clarify for a B6 beginner. "Base flight TrueBlue points" means spend x6 if booked on jetblue.com? Meaning if I book and fly $625 in airfare (I understand taxes and fees don't count) in 3 months, I qualify? Just want to make sure I understand the system here. 3x vs. 6x for booking via B6 website and definition of "base flight TrueBlue points." Thanks in advance.
