All part of the trend.
This is a clear attempt by Iberia to do a BA. It will bocome "fortress Madrid", as they hive off regional routes to Catair with crews on lower cost contracts. There is some local view that says politics are part of the issue too, but I'm not so sure.
Iberia pilots are all based in Madrid, so those in BCN are on a good deal and live in BCN permanently. Their lifestyle is the main victim I think. It is one more example of the way the industry is going.
