This isn't a big deal in the world of signup bonuses, lounge access, manufactured spending etc., but I'm always interested to better understand the rules and motivations of the credit card programs we use. The following is specific to Chase, but might apply to any other card issuer where you hold more than one account (not AMEX since they don't want you to notify them of travel). After returning from Europe, I got an email from Chase saying that I no longer needed to give them advance notification of travel for my CSP card. Since the email made no mention of my other two Chase accounts, I asked whether they were also included. Here's what I got back. "As part of our continuous efforts to improve your experience with your Chase card, we’ve made an update to your account ending in [xxxx] and you no longer need to provide us with your travel information on this account. Let me assure you that we will continue to monitor your account to detect any suspicious activity and may still decline charges that appear fraudulent. Please note that not all accounts have been updated systemically for travel information. For your account ending in [yyyy] and [zzzz] you will still have to notify us with your travel information. If you have any further questions, please reply using the Secure Message Center. Thank you,..." So, if I'm traveling and plan to bring two Chase cards (quite possible since one is tied to a hotel program), I still have to notify them. I don't see how this helps them or me. Anybody else encounter this or have an explanation?
