It really is quite immature to refer to it as "Open Lies" every time the venture is mentioned...
Nevertheless, this points to the true reason the mainline workforce should be worried. As I predicted in an earlier post in R&N, the new recruitment will be fed through Open Skies in the future, leading to mainline becoming a more senior, expensive, and eventually marginal "A-scale" salaried workforce, while the OpenSkies workforce eventually becomes the B-scale main body of the workforce, particularly if European expansion is a success.
I could easily envisage a situation whereby Open Skies takes advantage of the collapse of Alitalia or others, and continues to develop a well-regarded European business that is preferentially flown by business passengers into Europe / US / Middle East.
Without cadet recruitment into both pilot bodies, the business will be marginalised the future.
