Mile More Friends

Morning All,

Just a quick query please.... I recently recommended some friends to the FC via miles more friends on the website.
It says on the website that I will receive 2000 miles when they take their first trip. I have today received 1000 miles.
Does this mean I will receive another 1000 on their return flight ( technically their 2nd trip!)
Or do I need to query it??
Thanks all.... Happy Sunday

The next 1000 miles will be credited after the return flight

Thank you
