We have a thread in the WN forum where someone just got a Chase WN CC and quite quickly realized he/she should have waited until October, so the bonus points would post in 2017, crediting toward a longer Companion Pass.

In such a situation, if you immediately cancel the card before activation, what happens? Can you apply again a few weeks later? Will you be eligible for a bonus later if you never got it?

Will changing the credit card drop date (say from 20th to 4th) during the first three months accomplish anything as far as shifting the crediting of points?

Other repercussions?

How do policies vary among the various credit card issuers?
