scottmel, you haven't said what your pick up and drop off times are, exactly, or what kind of vehicle you are seeking. But I ran your dates (June 17th to the 27th) with a default noon pick up, noon drop off. Here are some of the prices WITH the code (which is working fine
) and WITHOUT the code (using the discount for Emerald Club members):
With KLM Code / Without KLM Code (using Emerald Club Discount)
Economy $279.50 / $570.32
Compact $290.29 / $577.84
Midsize $303.40 / $585.39
Midsize SUV $354.03 / $585.39
So there's a BIG difference when the KLM is applied.
That might be true for you, but it isn't for scottmel's dates. Nor mine. In my case, the difference is almost $400 in favour of the KLM code ($500 with the KLM discount vs. $871 with the Emerald Club discount).
I would suggest to everyone to run their own personal trip dates to see which offer works best for them. I, personally, will be watching Alamo closer to our travel date, as their rates seem to drop dramatically around the 4-6 week point.
