I ask because I'll be travelling in Feb and can really use the next two billing cycles on my card to pull in more points before locking down my flights. Currently have just under 47 000 miles and will need 60 000 miles for my travel. Either way, I'll need to pay a little to cover a gap, but it would be a shame to pay out more than I'd need to prematurely, as I'll be collecting an additional 6000 points or so on my next billing two billing cycles. Thoughts?
