Binghamton Airport (BGM) is a smallish regional airport with a rewards program. The program awards little trinkets sort of based upon the number of trips you take from BGM. One of the rewards was DL SkyMiles. I just received this note from the airport rewards manager:.. "As a result of a change to their corporate policies, Delta Air Lines will no longer be supplying their SkyMiles to our Business Travelers Rewards Program as of March 31st. We are not alone - Delta's involvement in many like programs are being discontinued in similar fashion..."
