Let me put it to you this way.

A bit ago, you had a dividing line between pilots seeking a job, of those who were "regional" pilots, and those who were "jet guys".

Back then, regional = turboprop, because that is all the regionals flew. Jets meant anything jet.

Now fast forward to today. It seems that dividing line is still there, but it is now "regional" pilot and "transport guys". Regional now includes all of the Embraer and Canadair jets lumped together with the turboprops, while transport means anything larger.

So...?

Let's be honest. Once you have flown something larger than a RJ, you are no longer "just a regional pilot" in the eyes of a potential employer.

Does that mean that regional pilots cannot find a job nowadays...? Nope. I assume you posted this post because you are a regional pilot who has been offered a job. Regional pilots have usually been able to find a job both in the past (when they were turboprop pilots), and today (when they are usually RJ pilots).

But...

Much like it is still "possible" for a turboprop pilot to get a job with no jet experience, it is far easier for them if they have had jet time as well. The same thing is starting to apply to those who only have RJ time on their resume. You can still get a job, but it would be far easier with some time in larger equipment.

Say you stay at XJet, and things go south. It is no secret that the RJ is not as popular as it used to be, and many regional carriers RJ fleets will shrink (or even cease to exist) much like the turboprop fleets. Where would that leave you then...?

Probably wishing you had made that move when you had the chance. Afterall, are Airbuses going away anytime soon, hmmm... Nope.

Do a search and try to find some pilots nowadays that were glad they stayed at one of the few remaining turboprop only airlines. Imagine yourself in their situation years from now (at XJet). Could you move on then? Would you move on to something worthwhile...?

jetBlue is a respected carrier to other potential employers. They have a high caliber training program and a good people. Even the naysayers on here can admit that. On the other hand, even though Expressjet is a decent outfit it still suffers from the "regional" stigma attached to RJ and turboprop flying.

Just calling it like it is.

Blame it on overall public perceptions of our industry, potential employer's ego centered opinons of one's own flying being different than another's, or unfortunate impressions (of all regionals) created by accidents and mishaps (like the Pinnacle CRJ crash).

If things go great for jetBlue, then you are set. But if things do not, then IMO you still will have a lot more options (than having stayed at XJet) because you are coming from a "large jet" enviorment, and can move on to something bigger and better than just the right seat at another regional.

Food for thought. Good Luck to you.
