What's the consensus on best churning strategy for the Barclay's USAir card? I've never held it before and I'd like to get the bonus twice before the merger is complete, if possible. I'll apply in the coming days, but for the 2nd round, what is the best avenue? Cancel immediately and immediately reapply, wait to cancel and then immediately reapply, wait to cancel and wait to reapply, or simply reapply as an existing cardholder?
