The September monthly Delta SkyMiles “flash sale” is out. First off you need to know how to search for open days since Delta tries to hide the multi-day feature on the home page. Then, since Delta also hides the SkyMiles award charts you need to look HERE on the blog to compare the user supported real Delta award charts.

A quick simple multi-day search from Detroit to Hawaii shows many open dates. Keep in mind as a Medallion you can only get free upgrades from the west coast connecting cities including SLC & LAS. If you have a single flight number starting in DTW, ATL, NYC, MSP etc. that connects through the west coast you can NOT upgrade either unless you can get the rep to break the flight into two parts (with the same flight number).
