Delta puts a specific award on sale usually each month and this month it’s economy roundtrip awards to the Caribbean.

Delta pretends to no longer have award charts. The truth is they are just hidden. That’s why they can simultaneously claim there’s no ‘regular price’ (false) and that they’re running a ‘sale’ off regular price (sometimes true).

With all the frequent devaluations it’s handy that Travel is Free kept an updated chart at least until Delta obliterated their partner awards earlier this month.

Key details:

• Economy awards between certain US 48 cities and select cities in the Caribbean and Florida start at 20,000 miles roundtrip
