It looks like a white elephant but what an elegant one! Corpus Christi appears to handle only connecting flights to Dallas and Houston (that's the international bit) with just three airlines operating there. It is light bright airy and wonderfully free of the normal hustle and bustle of a modern airport. Checking in took three minutes; passport control and security about the same - they have new full body scanner. Each airline has its own gate complete with airbridge to connect even to small planes.
