Delta, Expedia, Orbitz, Priceline, and Travelocity are all in the OP.
But airlines other than Delta (AA CO UA ... - OK fine, ur excused for not having Sun Country
) are not:
-For getting doublepoints if you book with a mileage program CC that matches the airline (assume that doesn't work when booking through a search engine), for one example.
-For booking without ticketing to hold price for a day (or more) when uncertain of travel plans, for another
