Hmmmm... so after 16 years with National (4 managing the internal billing of one of their top national accounts and 12 as an Emerald-plus at their top annual levels), I somehow got myself on their Do Not Rent list. Very bizarre... I returned a rental in FLL last Wednesday morning then flew FLL-DFW-LAS-LAX. Showed up at LAX to pick up my rental on Wednesday night and was told I was persona nongrata. Lovely manager on duty had me come around to the office and we discovered that I'd been put on the DNR list that very afternoon by someone at corporate for "unpaid damages" due to a chipped windshield (that I had reported myself, btw) at JFK from the fall. Since the corporate office was closed (and since I was on the phone with my travel manager wanting to know if they had contacted us at work - as they are generally prone to do on damage claims), the nice manager went ahead and rented to me. A talk with our corporate account rep confirmed that I'd been placed on there due to being "nonresponsive" to the letters they had been sending - to an address where I have not resided for over FOUR YEARS. Never mind that my profile is (and has been) current with my updated home address and I've gotten regular mail and another damage claim at my current residence within that time period and that National also mails to me at our offices (often resulting in double production of my Executive Elite card). So just a heads up... if you too get put on the DNR, press further. The local station can see exactly why and having the corporate office in Tulsa produce their documentation might be comical. BTW... a chipped windshield costs $165 to repair.
