In case people were wondering the code B868700 belongs to First USA Bank. I have seen this code for a long time in this thread but no one could say who it belonged to (even if you tried to look it up on that Avis site it wouldn't come up). If you use a code, on your receipt print out it will say the name of the company that it is associated with which is how I confirmed this code (for example, I've used the Citigroup Leisure Travel A074800 code before and that's exactly what it says on the receipt). I haven't had any trouble using either but the B868700 code isn't always the best consistently depending on where you are picking up or dropping off from what I can tell (though at times it does seriously beat the Citigroup code, which on the other hand is consistently a fairly decent rate regardless).
