Morals/etc aside, would like to hear any first hand experiences on this topic if possible.
Anyone still/have used corporate codes for car rentals after working for an employer?
Have you been audited/codes stopped working at all at some point?

I rented cars with National back with a former employer who had a corporate code. It appears the National loyalty program doesn't let you apply corporate/no corporate code on rentals when you're logged into the loyalty program. Agent said if I didn't want to use corporate rates (eg. cases for one way rentals where there is no mileage limit), I'd need to make the rental as a guest....

I'm hesitant to X/delete the code for any rentals because I'm not sure if I'll be able to add it back later. Anyone else have experiences with toggling on/off corporate codes while renting with their car rental loyalty program?
