I was south-east of the airport and the active runway was 24. The ATC said, "Make straight in and remain south." And then he said, "Margin final, cleared [to] land."
What is margin final? I'm an international student so I may have misheard. I thought it's for joining final so I said, "Join final, cleared to land." The controller did not say anything after.
If it wasn't "margin final," what could it have been?
