Nonstop Preference
This option indicates the display preference for lowest number of stops possible in the Flight Summary - regardless of price.
When this search criteria is combined with Surrounding Airports or +/-1 to 3 days, all initial prices and availability will be for nonstops only.
Note not all routes or airlines have nonstop availability. If you experience problems in finding results, simply widen your search criteria by unchecking the nonstop preference.
