I haven't done any commuting out of SRQ but I've been doing TPA to DCA/IAD for ages and I found it was easier than commuting to EWR. On paper EWR has way more frequency but there's a ton of commuters and if you're on reserve and have to crosstown to LGA it's a giant pain. The metro connects DCA to IAD and there's enough BWI guys/gals that I only saw it once on reserve. Shouldn't take too long to hold MCO so I'd imagine the commuting won't last very long, maybe a year.
