Has anyone successfully added an airline frequent flier number to an international (non-US) reservation? There is no field for the FF# when I look up the res. online and when I called I was told that the number can't be added but maybe it can be added at the pick up location. Seemed weird that Alamo doesn't have the capability to do this.
After emailing and speaking with Alamo CS reps. it seems that my rental booked through carrentals.com is ineligible for FF mileage accrual. It was a very good deal but I have never run across a car rental that was not eligible.
