I know this sounds crazy but I was flying in the 2nd JS up to STL from HOU. The three SWA guys were talking and one was a chkair and he was describing the sim setup they have. He said there are two open sim bays with nothing in them. Initially they were going to have additional 737 sims put in but that has been haulted. He heard rumor(i know i know) that SWA was going to cut flights into high traffic places like LAX and Vegas. Said the company was looking into doing fewer flights but with larger aircraft to ease congestion, lower ASM cost, and increase ground operational efficiency at those airports. He sighted the 787 as a possible cadidate. Don't know how much I believe that part. He said with oil the way it is SWA is looking at all possibilities.
