I will be going to Korea soon and will be meeting my wife's three sisters and one brother and their spouses along with their children (all adult males). All of my wife's siblings are older than I am. Their order is, oldest sister in law, brother in law, 2nd oldest sister, 3rd oldest sister and then my wife.
Naturally I am practicing my Korean, but I REALLY want to make sure I greet each of my wife's relatives correctly. Can someone please help?
Additionally my oldest sister in law is flying into Seoul at the same time we are so I would like to ask her "Good to see you, how was your flight?" or something along those lines.
