Couple of thoughts...

Do you see yourself being at a regional for at least another 5 years? If so, why not go to a wholly owned with a flow? If you think due to pilot shortage issues that there is no way you will be at a regional in 5 years, maybe its best to stay.

Another thought, if you are considering a lateral move, why not first try and get on with an LCC such as spirit, allegiant, or frontier? Regional FO's are definitely getting hired at LCCs.

Final thought is a company like RAH has shareholders to be accountable too, whereas a wholly owned carrier is just a cost center to the parent airline. As a result, the wholly owned regional can continue to see pay and benefits increase as the pilot supply gets tighter and tighter.
