My points have built and built....

For years we've built our chase rewards using reserve, preferred and freedom.

My balance is about 750K.

We're retired and plan to one day take a big trip and we held onto the points for a transfer for business class. But right now new grand babies and some operations have put that off.

But I worry about programs ending or somehow the points losing value. Right now we mostly use AMX and Delta while flying about once a month.

Are my points safe? Is there some massive bonus I could transfer into for them to sit with another partner? I appreciate any advice.
