I could not find the information in the program rules about what happens to your Barclays Miles in the event of death. I emailed them. This is their response.
“In the event that the primary card holder passes away, the account will be closed. Be advised that upon closing your account, the benefits and rewards that you are enjoying with your Barclaycard Arrival Plus World Elite MasterCard are also forfeited, including the miles you have earned with us.”
In other words, make sure you use your Barclays Miles before you die!
