Are you looking for a Captain of F/O position on jet?
I have 3500 hours TT ( 3000 hours heavy turboprop ATR72) rated on B737 and it is almost impossible to find a summer contract on B737.
Turboprop hours nowadays will get you nowhere, airlines prefer guys with 700 TT and 500 hours on type.
The only solution is to have the "golden contact" that will make you get in….
