Well I guess we all know now that we WILL get the miles.

BTW, you're confusing Miles with Kilometers. 1000 miles=1600 kilometers. So the conversion is (and always was) 1000 AMEX MR points = 1000 miles (=1600 KM).
The HHonors conversion is 5000KM=10,000 HHonors points. 5000KM = 3125 Miles, so nothing has changed.
Mexicana seems to sometimes get its miles and Kilometers confused on its website, but the above is the actual conversion.
That makes Mexicana BY FAR the best airline miles to convert to HHonors points you get around a 60% better conversion!
I'm loving this whole deal!!!!!!
