The airport there is LRD. Don't expect airlines to fly direct to every destination in the US, there are literally thousands of airports in the US.
You can fly any airline that goes from HK to the US, then take connecting flight, either from the same airlines, or from its partner.
American Airlines, Delta and Continental all fly to Laredo. Continental fly to HK but it only go the the East Coast. If you want cheap ticket, try find Korean Airlines, Hong Kong> Seoul Icheon > Dallas > Laredo ; or HKG>ICN>LAX>LRD. From Hong Kong to Dallas/LAX will be on Korean Air, the last leg on its partner Delta.
The most direct flight will be on Cathay Pacific. HKG>LAX>DFW>LRD. HKG to LAX is Cathay, from LAX to LRD will be on CX's partner American Airlines. Cathay however is the price leader and you can expect them to be more expensive.
Other routes are also possible, and depending on the season and seats available price vary. Check with an agent and they should find out for you.
