According to this sticky

SW is still being tested at POP. Tyler does a good job keeping this information current.
I don't think we'll ever hear status. Either a poster will tell us what resorts have added SW or a poster will tell us POP is no longer checking luggage for SW passengers. I suspect a lot of the issues is how MCO and SW can handle a large volume of bags hours in advance of the passengers flight OR how how efficiently can Disney/BAGS hold the bags at the resort and send them to MCO on a timely basis. We'll never know what is happening behind the scenes.
I don't want to sound rude but there really isn't any reason to bump this thread. I'm 100% certain a DIS will start a new thread when/if SW check in is added to additional resorts or when/if the service at POP is discontinued.
You want made up information? Assume a 30 day test and 7-14 days to evaluate the results.
