Skullflyer- These commuting questions come up all of the time. Either through the thread or via PM. Everybody on here working for Saudia have made it very clear and very honestly that this is in no way a commuting contract. You do get a block of 5 days off per month but rarely does that extend beyond 5 days.
Sadly people come to Saudia having ignored all the information and EXPECTING to be able to commute. They spend their time complaining and making people who are very happy working for Saudia miserable.
The other point is that you get the type of aircraft which they give you. If that's going to be a hardship then don't come. In all likelihood over the next few years the vast majority of experienced widebody captains will be put on the A330.
Another point; it is still only about 50% who start that are still with the company after one year. I'm not sure of the percentages failing or just chosing to leave.
