FWIW a friend of mine has tried twice to leave JB and come to SW. For him itd about pay per day. He can make more at SW for the same days or fewer. Also he lives in MCO and at SW it's much quicker to get as FO. As Cpt, forget about it, but for him FO pay at SW is enough for now. Obviously he didn't get the opportunity and now being there 3 yrs he's going to stay. Not worth the move now.
Maybe something to consider. Jb is going to merge or buy or be bought at some point and there is not as many pilots on their list so the integration might be different.
Sw days they want to grow organically and if they did buy someone I can't see it being anyone of size.
