So I guess from the responses, Jet time seems to be preferred by airlines, if you are to be flying a jet, which makes perfect sense. But does that mean they will not look at your Turboprop time? Or does that simply mean they would prefer jet, but will still accept turboprop?
Unfortunately B767PL you are asking for a specific answer to a general question. Each airline will have different views.
bmi Regional (who fly emb jets) have taken direct entry captains will little/no jet experience. BA would take you as a direct entry pilot with turboprop hours only (or they did a few years ago anyway, don't know about now).
Ryanair will only take you with a 737 rating and 500 hours (and specifically 737 - not any jet).
So the answer is - it depends who you are applying to. Take a look at
www.pilotjobsnetwork.com and click on the operators to see their details.
And remember - this is a fluid marketplace; just because airlines are happy to take a certain experience level now - it doesn't mean that will next year
