Also, check your airline programs to see if they're offering the same amount of miles. I'm not sure if JetBlue is the only one out of all of them that does this, but JetBlue is also a RewardsNetwork earning partner and they keep it simple with a terrible earning rate (compared to other programs which earn 3 or 5 miles per $ depending on whether you have VIP status) and no increased rates due to VIP status (in fact, their program has no status levels at all).
