Input: Question: Who is the mayor of the city that Delta Connection ended service to on May 1, 2008? Passage:In later years, Continental Express continued to serve the airport with nonstop regional jet flights to Cleveland while Continental Connection was operating nonstop turboprop flights to Albany, NY; however, both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur only to drop it soon after. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008 following a mid-April announcement that Delta and Northwest Airlines were planning to merge – a move that led to changes for the merged airline.
