Added a note that Delta now enforces married segment logic on awards, and requires individuals and agents to search O&D instead of piecing together itineraries point-to-point. Delta's systems actively attempt to prohibit point-to-point ticketing, and even if you are successful, it will result in additive pricing even if the routing would normally be allowed between the origin and destination. This is dramatically reducing the number of available results, especially on international itineraries involving partners.
