Papazulu,
From the jobs section of the Jet2 website the requirements are
Minimum requirements to apply for Non Type Rated First Officer are as follows:
- A minimum of 1,000 flying hours, of which 500 hours must be medium military or commercial flying on rotary or fixed wing turboprop or turbo jet aircraft
Anything less than this counts as 'low houred' even if you have 10000 hours instructional on a C-150. The low hours refer to experience on medium turboprop or jet aircraft.
