I've looked on the internet but can't find answers to my questions. Hope someone can help me...

We'll be arriving SCL on a LAN Business Class ticket... LAX-LIM-SCL.
1. We don't deplane in LIM so, am I correct that we're considered international arrivals?

2. We arrive SCL in Terminal 1. Is that the international terminal?

Our friends arrive on LAN 30 min. after us, coming from MIA. Can we wait in the LAN lounge for 30 min. and meeting them at their gate when they arrive.
3. Are we able to access the SCL LAN lounge after arrival?

Thanks for the help!
