Dallas, TX – Dallas based Southwest Airlines says it more than doubled last year's 4th quarter profit and beat analysts' estimates, by earning 15 cents a share. For the year, the company made 645 million dollars, or 84 cents a share, compared to last year's 500 million dollars or 61 cents a share. CEO Gary Kelley praised workers for turning a profit in a tough year of traffic & weather delays, and record-high fuel prices, adding that earnings fell short of initial goals. The carrier also slowed down delivery of some jets, and will soon install inflight internet equipment to test on 4 planes this summer. Bill Zeeble KERA news.
