I'm thinking of getting the no fee Barclay Arrival card. I need to spend $1000 in 90 days to get the 20K miles. So I can do that in my first purchase on a couple of plane flights. So I assume I'll get the 20K miles after the first cycle closes. It seems like I can redeem for travel statement credit for travel in the last 120 days. After I pay the balance off in the first cycle, can I then apply for the statement credit for the plane tickets for the next cycle even if that would give me a negative balance (credit) on my statement?
