What happens if I miss an international connecting flight?

Don't worry too much about it, they will put you to the next flight if you missed your flight due to the previous flight delay. But like the previous answer said, you may have to wait a while until there is an available seat. This happened to me before, so I know. As soon as I arrived in Korea (layover), a lady was holding a sign for my next flight, and I thought, why would she have to do that. So I went over to her and told her that's my flight number, what's up? She said I had 30 mins before my flight is taking off and suggest that I start running. Lol! I breezed thru the security checkpoint after I explained to them what's going on, and they put me through first in line in the queue. I got in 10 minutes before take off.
