The Alternate Airport Shop API allows you to define up to 20 airports per origin and/or destination. The API returns the lead fare (either nonstop or overall, whichever is lowest) with the corresponding flight itinerary and fare breakdown for each lead fare.

The Bargain Finder Max Alternate Date Shopping API functionality allows you to specify multiple itinerary options and date pair combinations per request. It does not only help the end users find more desired travel dates, but also provide more itinerary choices within each data pair.
