Couple of years ago, a reservist buddy of mine was deployed to Kuwait for 6 months. He had recently applied for a Chase credit card with bonus points and was 3 weeks into his 90 days spending time frame. So he contacted Chase about deferring the spending time frame till after he came back from deployment. All he had to do was send a copy of his deployment orders and that was it. Chase not only allowed him to complete his spending for the bonus points after he came back but they threw in a couple of more perks, I forget what those were.
