Software for performing task automatically?

[bholabhala]

Good day
I am searching for a software, capable of automatically performing a pre programmed task. Let's say, i fly very often and in need of cheap tickets. I want a software, capable of going to a specific URL, entering information requested, and searching for flights.

Any automated software out there that can do this?

Help me out.
