I have a 12,000 mile trip coming up and have the choice of banking the miles in my Delta Miles account or One Pass account. I have accumulated more than 50,000 Delta Miles and hope to use them one day, but would need more for a good foreign trip. I have nearly 10,000 One Pass miles and 12,000 more would still not get me all that far. However, with Delta in bankruptcy, I am wondering if I should be trusting that Delta miles will be usable even after I accumulate what I need. They are currently usable in the One Pass system, but not combinable with Delta Miles. Any thoughts?
