So I called Delta about the last leg of a trip not giving milage with the reason code N although the first two legs of the trip have given the mileage. The last flight was delayed in AMS because of weather and rebooked to a later flight and after that, the Fare code changed to R instead of X for that flight on KLM AMS-GOT. I waited a few days then emailed Delta and they said they fixed it, but then it just showed up in the activity but not showing any Mileage saying that it isn't eligible for any miles. That is when I called Delta and the Rep said that in order to get the miles I need to get on the return leg in November to confirm that I actually took the flight last week. That doesn't make sense to me as I've flown both KLM and KLM city hopper and always gotten the mileage a day after the Delta operated legs cleared and not have had to return to the US for it too clear.

So was she correct? I just haven't ever experienced this or heard of it before.
