JACKSON, Miss. (AP) — U.S. Sen. Roger Wicker, R-Miss., is asking Silver Airways and Delta Air Lines to speed up linking their computer systems to allow customers using the Delta web site to book travel to four Mississippi airports.

Airport managers say the inability to book flights through the site is driving away passengers who otherwise might fly in and out of Tupelo, Greenville, Meridian and Hattiesburg-Laurel.
