Hobby HOU is the traditional Houston base for Southwest Airlines which is well used for quick regional flights. Only recently has Southwest got a piece of the pie at Bush IAH.
Before Bush was built, Hobby was Houston's main airport. But that was a long time ago, 1927 through about 1969 or a bit later for Hobby.
Just for grins, I looked up flight info for
non-stop one-way flights leaving the Houston airports and going to Dallas (DFW). For May 2, 2019 there are 25 flights from Hobby and 17 from Bush. Coming back to Houston from Dallas on the same day are 23 flights to Hobby and 16 flights to Bush.
These numbers might be due to people on the north side of Houston simply driving to Dallas since the drive north is shorter for them.
