You keep saying hub...that’s not the right word. I think you mean base. A hub is a big airline base that serves the hub and spoke model. A base is a domicile where you are assigned...not necessarily a hub. It’s all based on seniority and varies airline to airline. Usually places like NYC are junior bases at airlines that have bases there because of the cost of living. You don’t get paid more for being based in a high cost of living area, which is why they tend to go junior. For reference, the most junior FO at my airline’s most senior base could hold captain at our junior base. Base/equipment/seat is all seniority based, and you’ll figure out where you can hold the best pay/QOL based on your commute and lifestyle. As a regional guy, most airlines only have one or two planes...figure out what bases you can commute to the easiest and go to a regional with a good contract and good movement (ie not expressjet) so you can get some seniority quickly.

Friends don’t let friends go to gojet (unless maybe you live in one of their junior bases). I have an army bro who lives in Huntsville and is starting at endeavor in July. Highest pay and one of the best contracts for regionals. PSA may work ok for you too. But check out endeavor since getting to ATL would be fairly easy and cheap from HSV.
