From what I hear SXS do actually upgrade foreigner FOs, many Dutch guys in process with minimum 4 years experience so if you look at the THY "group" and exclude THY/LTH but include SXS,SXD the system does provide for " early upgrade" of course, to enter THY mainline as a DEC from the other " group" companies you would need to meet the requirement of THY mainline, probably means flying as a Captain in SXS for 4 more years or so. As I said, don't worry about upgrade as a foreigner FO in THY mainline because it will never happen while the sun shines;
