Just heard about this. Sounds great esp for people who already have plans a year out.
You don’t need to have an AP (you just need tickets). We booked 2 nights after our cruise and had a Bounceback booked Thanksgiving week. When I called 60 days in advance for the April trip we were approved through Dec 4 because we already had tickets.
Now if we didn’t have Nov tickets booked then
DAS would only be valid until the end of our April trip UNLESS we were APs.
