As I was going some reading I saw one post that said this KLM code is "controversial." Can anyone tell me why? Thanks!!
Because, some people, despite having countless assurance from National Car Rental itself, "can't believe" they can actually get a somewhat O.K. discount, including LDW, etc.
So, countless people on this board have called National (and probably) KLM over the past six years or so and been told, yes it is all good.
Yet, as Sonny and Cher sang so long ago "The beef goes on

"
If, you don't feel comfortable, don't use it. Personally, IMHO, before all the "nervous nellies" called in about it countless times, I think it was actually a better discount than it is now. It worked all the time and for every rental. Now, not so much. Would not be surprised, since it comes up on here about four times per week, that it will eventually be killed...anyway, it works, National says it is good...
There are actually a couple of other codes that get me a better rate, but no way am I going to share them here....see the FlyerTalk Forums if you want to see a long discussion about that.
Anyway, for a really, truly, no controversy code, that sometimes is even better than the code you asked about, join the national emerald club. Their generic Emerald Club contract ID will sometimes (note I said sometimes) give rates much better than aforesaid code.
