Regular rates at ECP are usually more expensive than VPS, but when you get the teaser rates, they are cheap, cheap, cheap, like $30 to Nashville, $60 to Chicago, etc, and bags fly free on Southwest.
I think it's interesting that VPS carriers didn't start getting competitive until after ECP came online. VPS now also advertises heavily on local area TV stations. Good old fashioned competition is good for everyone.
Since JOE is essentially "leasing" the Southwest jets for the next three years, I'm sure they have more than some say in determining the when and where of cheap, cheap, cheap teaser rates.
