I just went through my purchases since 10/1/17 and everything but a few transactions has tracked correctly. Honestly I probably forgot to start on jetblue.com for those missed transactions. Seems like it takes about 30-45 days to post but when the points posts on jetblue.com it uses the original purchase date.

I tracked about 5K TrueBlue points in 3 months; pretty happy combining this with MileagePlus X & AT&T Access for 6.5x return on regular spend.
