Southwest Airlines began scheduled air service out of Dallas Love Field in 1971. At the time they flew only intra-Texas routes, escaping regulation by the federal government’s Civil Aeronautics Board which at the time set airline routes and prices.
Southwest Airlines is known for alcohol — from Herb Kelleher’s love of Wild Turkey, to the free drink chits that used to come with award redemptions, to becoming the largest liquor distributor in the State of Texas to fend off competition.
