That is good news. Hopefully they will expand to other cities and or Southwest Airlines will expand to other cities after Houston Hobby airport has it's international terminal built.
From Houston it is just so much harder to get to the DR then to go to Mexico. For short trips it is hard to beat the price and shorter direct flights to Mexico. They could increase the tourism a lot more with direct flights.
Americans like nice casinos with good sports bars like I have mentioned before. I still need to check out the Hard Rock Casino but others nice ones would help.
