One more addition.
If You are looking for Your value in the pilots market, i. e. if You intend to change companies, go to the sandbox (for information on how wise this choice would be, head on over to the
corresponding section on here) or prefer the expat life, the Airbus it is, no doubt about this.
However, if You are looking to stay in a solid company or group of the same, which is LH and its subsidiaries, come to OS. Consider the longevity of some of LHs ideas, look at LH Italia or Jade Cargo for example, and then think about how wise it is to be associated with Germanwings. At OS, You are at a legacy carrier (although there are internal problems galore), have the option to fly for 2 years, expect a reasonably quick jet rating, and after 2 years, You can still make Your choice between whatever may be on offer within the company.
