Has anyone had any luck having another airline match the Mosaic status (ie to DL Silver)? Just curious . In theory I good get mosaic status again by doing a Mint Run to SFO but I am not sure it is worth doing. It would cost 1000$ (I have a jetblue credit ) and I would get 20000 points (15K from mosaic + 5K 6 B6 flights) (which I value at about 300$) and the free change fees (I value at 100$),
Even More Speed (50$) , free luggage (64$), more points (25$). Its a better investment than the stock market though.
