The lady on the phone indicated they would expire in two months from that day, which will be March 18. I asked if the website would state this when we logged on and she said that it would not, it would just say the completely unhelpful standard line: 6 months from last activity. So, I think you could make the case that when the points were reinstated that was 'activity', and that you should have 6 months from that. But I am sick of these yahoos, so the day that the points were reinstated we booked travel with the miles and we're done with his account.
My husband has 7,000 miles remaining after we booked our travel, so I inquired about transferring them to my account. I too have a credit card so my account will remain active (as long as they don't change that policy and tell no one, also!) as long as I keep using the card. Anyway, I asked if I could transfer the miles to my account, and the person I was speaking with said they used to be able to do that, now they can only transfer in instances of death or divorce. So his 7,000 miles are just going to waste.
