Chase has a 48-month rule for customers to receive new cardmember bonuses within the Chase Sapphire card family. This means if you’ve earned a Chase Sapphire Preferred or Chase Sapphire Reserve sign-up bonus in the past four years, you’re out of luck to earn this bonus until you’ve passed the 48-month mark on the last bonus. And keep in mind that the 48-month rule applies to when you received the bonus, not necessarily when you applied for the card. Additionally, you can only have one Sapphire credit card open at a time, which means those who are current cardmembers of the Chase Sapphire Preferred, Chase Sapphire Reserve or the no-annual-fee Chase Sapphire Card (no longer open to new applications) cannot apply for this card or receive the bonus.
我本也想这么干，但是网上说不能同时有两张sapphire卡，所以我的理解是先关后开，如果可以先开新卡再关旧卡，就更好了。
要隔一段才能申。我当初关卡后一周申请没批，过了一个月后再申批了
这是新规定吗？我以前是有preferred 申请reserved，申完之后要关卡，chase给我降到了没年费的sapphire 并没有关掉。现在还是两张sapphire。
