Of course, you're right. For now, I'd guess that it will all begin and end at DEN
appears to be "testing the water" with it's expansion into something slightly different from the other LCC's.
With the exception of HP
(which is a "convert" LCC), not many of the others are expanding much internationally.
BUT - by the end of this winter, they will start to have some idea of how much support the Mexican destinations get from, say, SMF
. This could affect decisions on adding service from any of those or other cities, as non-stops.
Eventually, I'd be sure that they will add service to other cities that doesn't originate in DEN
. If only because, at the present rate of growth, they're going to run out of gates at DIA within a couple of years. Again.
Also, at the moment, they're all leisure destinations. I'd like to see them add a "business" city, such as Monterrey, Mexico.
