Hi all,
Could someone please explain to me exactly how JetBlue's base points are calculated? The website describes it as being "3 points for every dollar spent at JetBlue.com" but this seems to be an oversimplification. I've tracked my spending on each of my 12 flights this year, and it actually seems that my base point earnings are more like 2.8 times the dollars spent (or 3.22 times the pre-tax dollars spent). Does anyone know what is going on or how the exact calculation works?
I'm bummed since I believe I missed out on Mosaic for the year by 15 points.. when I calculated the points I'd need I was using exactly 3x.

Thank you!
PS. On a related note, has anyone been in a similar situation and had any luck pleading their case to JetBlue? 15 points is the equivalent of $5 spent with the airline. Is there an easy way to earn 15 base points without having to take an entire flight?
