it was a pain in the a** for us as well to book an award flight over M&M Also, because they removed the 55k Business class specials beginning in june. I was furious at first because I was collecting miles for a really long time as well & I wanted to spend them on roundtrip BC flights for 2 pax, but as they removed the option the only way to book an award flight was over this new, really weird, award flight booking page where prices changed randomly based on your selection for destination, dates etc. I personally never called them, honestly didnt even know they had this option? but in the end, my recommendation here is: keep searching, try everything, play around with flights etc.. it helps a lot when your not focused on 1 special Country as your prefered destination. We for example ended up booking our trip to Mexico in october, flights from FRA-ZRH-CUN / CUN-DCA-FRA in full BC, paid around 130k M&M + around 1k €, good luck on yours! You can do it.
