Can I exchange a certificate without redepositing points? I have a BXP1A certificate that I redeemed with expiring points last December. I haven't been able to use it yet, but am booking award seats to Hawaii and was wondering if I could add another 1000 points and use it for that? I obviously can't redeposit the points as they have now expired. I thought I had remembered that this was possible, but now I can't find anything suggesting that. Figured it was worth a try. Thanks!
