I think everyone is different and has this or any job for different motivations. Age and family situation play a huge part in this decision. I have flown with both, guys ready to leave and those who have been here 9 years.....and not looking to leave. The capt I am flying with now is looking to leave.... it really is not a black and white answer to this question. The fact is that not everyone at a "jet" ( regional ) carrier is hireable at the major level for one reason or another. EVERY company has a group who will stay... and those that will leave....... to use a blanket premise that RAH or SKW or XJT or ASA or whomever should ONLY be used as a stepping stone just doesnt hold water.
