i would say RAH has the base you want and is a solid company. It also has a more predictable or secure upgrade... lots of merger talk and uncertainty in every regional right now and you shouldn't chase the upgrade. you could be in the base you want, decent qol, and alright pay. RAH would be about as good of a choice as any but if you have until the end of summer to decide i would just keep my ears tuned to this merger talk. Depending on who merges with who you could see a lot of consolidation (people on the street) in the regional world.
i work for XJt and have nothing bad to say about it. it had the base i wanted, ok pay, and a good contract. My companies future is less stable then i would have liked but i have a great qol in the meantime and my companies future isn't as bad as many on here will lead you to believe. RAH makes better sense if you want PIT though. good luck
