It is difficult to lose a parent and you shouldn't have to think about these things at a time like this.
Do you have online access to the account or (if you think there has never been online access) physical possession of the card?

We have the physical card. Haven't tried to gain online access yet. It's probably not something I'd be overly worried about, but in this situation, we'll be traveling a good distance back and forth to wrap up his affairs. The mileage would pay for 8 tickets on JetBlue, which would severely cut down our expenses. My guess is that I could leave the account open and issue tickets from his AMEX MR points by transferring them to JetBlue.
