I've never shipped into Corpus Christi international, so I am not sure what flights may be available for shipping dogs into Corpus Christi... I've shipped into Houston on Continental many times as either the connecting flight or final destination. Most of my puppy clients in South Texas just make the drive to either San Antonio or Houston for puppy pickup... It is 2 plus hours from Harlingen to Corpus Christi according to mapquest. I've made the 4-5 hour drive from Oklahoma to Dallas Forth Worth (DFW) airport many times to pickup a dog so a 5-hour drive doesn't seem out of touch.
