Wow, big deal, 4 lines when they have 686 airplanes (Southwest+Airtran).When I was at EAL, we had 8 lines in MIA and a couple in ATL for 300 aircraft. How many lines does AMFA now allow in El Salvador? 6? How may do they still have at the domestic hack shops? How many lines does AA have for their fleet of 620 aircraft? How many shops does AA have for engines and components? With 686 aircraft (66 more than AA), why doesn't Southwest do ALL heavy overhaul inhouse like AA? After all, they certainly have the volume to justify it, right? They are not a little intrastate Texas airline anymore, right?And they can pay these thousands of would be heavy overhaul mechanics $45 an hour with benefits, right? Surely the great, never do wrong, employee friendly, Southwest can see the financial wisdom of doing all heavy overhaul inhouse instead of a third world country, right? The fact of the matter is SW can pay it's AMTS what it does is because of those 6 lines in El Salvador in addition to the domestic shops; you know it, I know it, Southwest knows it, AMFA knows it, EVERYBODY knows it.
And as for job security for their current employees, easy to do when there are so few to begin with since they never had heavy overhaul.
