I dont care if SWA taxies fast or not,,,makes no difference to me personally. However being a student of the universe I do find it interesting that all the other carriers,,,legacy's, low cost, regionals, freighters, etc. all taxi at relatively the same speed... 15KTS is our SOP,,,and believe me we are not "waiting for the numbers" as an earlier post suggested. SWA is the only carrier (that I have seen) that consistently VISIBLY taxies faster than everyone else. Do they know somthing that the other pilots for these other carriers do not?
