Does anyone have any insight on if Jetblue will eventually add something like Mint upgrade certificates as part of the Mosaic program? Not very competitive with other FF programs, and I'm finding that the price difference from economy to Mint is usually in the $1000 range these days versus the sometimes $300-400 difference on legacy carriers on similar transcon routings (that being said, I have been shelling out the cash so one could say their strategy is indeed working).
