I have to admit I never really looked into this, so any thoughts would be appreciated. I know there are clear advantages to showing loyalty towards a particular airline/alliance program, and going out of your way towards accumulating miles with them even when you're not flying. Whether it's miles for upgrades / flights or status / perks, there seems to be a clearly defined "goal" that you can achieve with the airlines. Hotel programs seem to be equally clear. Stay with a particular chain and spend money with them to gather points, and those points and stays grant you access to specific perks at different levels, and the perks are "nicer" as you progress towards the upper tiers. Now car rentals in theory seem to have a similar setup, but it appears that in reality, things don't actually work as well. Browsing through the forums here (and elsewhere) it doesn't seem like you get as much bang for your loyalty as you do with other programs. Not sure if it's because the cost of the actual product is that much lower or because it's a different kind of business (car rentals seem to be a loss leader, with the company making money of the extras you purchase?). Either way, does anybody have any thoughts towards why someone should pursue status on a particular car rental program, rather than just go with whoever is cheaper? And if anything, who has the best perks or easiest / best opportunities to "level up"? I mean from reading people's experiences it almost seems like upgrades are "iffy" at best, depending on the location/time and you rarely get anything worthwhile.
