This is a Tamper Monkey script that will automatically run when you search for a Southwest Points fare. It displays the Base Fare, Number of points per dollar required, as well as the paid fare class. The output is ugly, but I'm going to clean that up.
It requires Tamper Monkey to be installed first.
You can install the script manually, or just click on this link to let Tamper Monkey figure it out.
It will automatically keep itself updated, as long as you allow Tamper Monkey to auto update scripts.
Let me know if you find any bugs or situations where it seems to break or provide incorrect data.
Also let me know if there are other things that it can do that might be useful.
