Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - multiple frequent flyer accounts

Hi. I was just curious why Alamo.com allows you to put several frequent flyer accounts on your profile. Is it possible to get credit for all the frequent flyer programs you put for the same rental? Just wondering. Thanks.

You only get credit on one ff program. But you can have multiple on file and select one of them when you rent. It just makes it easy for them to not have to type the entire ff number each time.

Cap...Ya hit the nail on the head. That's exactly why.

Some people don't carry around with them all their FF numbers and they forget them, or they want credit for an airline they didn't fly...so it's easier to have them in the rental profile. It's handier at time of rental.
Don't forget though...depending on the airline...their's a fee to credit the FF miles. And the fee is taxed... I know. It's not nice...but it's a fact. Highest one seems to be Southwest...
