strictly speaking, outsourcing would be in the BA/Iberia venture in the Int'l market. Outsourcing domestically would be the same GUAGE equipment to another operator. That was Reno and Canadian Air. When it ends up at the regional level whose CASM's are easily double mainline, then it is trying to salvage a market if possible before dropping it. If the market supports it, mainline will fly it. Mainline is not searching for tickle feed, they have always sought the cream that rose to the top. They are trying to preserve the network with RJ's if it can be saved. Movement between markets goes both ways: to the regionals and then back to mainline. Honestly, it would be foolish to do all of your sampling in this economy and make universal statements about regionals taking all the flying. It's survival mode gentleman. Look longterm.
