This makes about as much sense as their line of credit policies. I provided them with documentation of my very high net worth, but because my income, purposely scheduled at an amount way below my means, my LOC is locked at $22,500.(I lied to get that much). I've already charged $25,000 since my renewal in August - $16,000 of it this month. The only reason I don't cancel is because I earn non-flying miles faster that with other cards.
