Major change?

So I was planning to attend University of Houston for Biotechnology. I originally planned on doing aerospace engineering and transfer to UT Austin, but U of H doesn’t have that program here. Should I change majors to something different at U of H, or transfer out my freshman year and change major at UTA? I also was offered CAP for Aerospace engineering at UT Tyler, but I heard its just as hard to get into Cockrell for engineering even for CAP.
