I just tried this but didn't get what I hoped for. I just applied for the card, received it, met min spend, and I wanted to close the month so my bonus would post faster. I have not been through a full billing cycle yet.
I was told my closing for this month is 2/25 and due date is 3/10. I asked to move it closer. He tried and said he could change the closing date to the 2nd of the month, and the due date to the 27th but it won't take hold until my second month's billing.
So I will close this month on the 25th, due date 3/10. Then close again on 3/2, due date 3/27.
I'm hoping to use my sign up bonus points for April airfare. How long until bonus points post? Am I being unrealistic to think I can get the points in time? I keep checking the flight availability and so far, ok, but who knows how long that will last.
