Continental is headquartered in Houston. They have about 16,000 employees in Houston. They have a hub in Houston which means direct flights on Continental to almost any major city in the US and many direct flights overseas. With the merger (since they are the smaller airline), Continental will be lost forever as part of United. I assume/hope UA-CO will keep the hub in Houston for access to Latin and South America but I assume that many of the direct flights will become flight with a layover in Denver, etc. If too many the (direct flight) routes are canceled/unscheduled, Houston could lose businesses. Worst case scenario for me: some faculty members spouses (not in academics) need to relocate and hence we lose some good faculty members in our department and/or at Rice. Almost surely, I am being paranoid.
Basically, I am just upset because I really do love flying on Continental (good customer service, decent planes, etc.) but have had less than stellar experiences on United the last times I have flown with them. It makes me sad to see them go.
