Any tools to automate checking difft codes?
 

I haven't found any real consistency in which discount code gives the best rates for any given rental. As a result, I manually enter many of the codes I have until I find a good rate. I repeat this process with several rental car companies.

Even limiting codes to those to which I am legitimately entitled, that's still a lot of codes. Since I don't check them all, I always suspect that one of the unchecked ones would have been the winner.

How does everyone else check the impact of different codes on pricing?

I'd love it if I could enter all the codes to which I am entitled once, and a tool would check pricing for each one. Does anyone know of something like this?

I thought people would find this topic interesting. Should I ask in a different forum?

That would be a great tool, but I really don;t think it exist anywhere!!!

It may be worth posting in the mileage run forum. Not because this is a MR, but because they use several software tools to help with routings and availability.
