Don't they already do this thru their code share with Alaska? I think I'd pick the first class seat in a 737 or a SWA coach seat over the "first class" e175 seat. But I'm just a pilot. It'll work great till the first flow control into SFO than it is really just 7 flight because they can just CNX every other flight and combine the 30 passengers onto one rj.From Airlineroute.net:
