I was hired a year ago at an LCC (JetBlue) with about 500 hours more than you. Time distribution was pretty similar however I had over 1000 jet PIC. There were 1-2 guys with around 3000 hours and several with no turbine PIC time, however I was the only one with zero 121 experience.

It’s definitely possible, however it seems still
to be the exception rather than rule.

All you can do is make sure your application is as polished up as it can be and apply everywhere you think you want to work. If you don’t have your apps in, nobody is going to call.
