The sad thing is of course that the strikes will achieve nothing
Regrettably, this is true in the current climate, and I speak as a strong supporter of Trades Unions. The setting up by Iberia of a low-cost arm - Iberia Express - sounds to me like a last-ditch stand and has appeared at a time when the low-cost market is depressed and likely to get more so. I have flown with Iberia and have a friend who is a FO with them. I hope for his and his colleagues' sake it works out but I am not hopeful.
