We are planning a trip to Chile from the US in March of 2007, and will be arriving in Santiago at 7:41 AM on March 13. We would like to make connections to Punta Arenas that same day. LAN Chile has flights at 11:15 AM and at 12:40 PM (I know these times can change, but assume there will be something similar). If our incoming flight is more or less on time, would we have time to go through customs, etc., change terminals, and make one of these flights without too much concern? Or should we plan to overnight in Santiago and go on to Punta Arenas the next day?
Also, we will be flying from Puerto Montt through Santiago and on to Calama on March 27. About how much time should we allow in Santiago for changing planes? Are LAN flights pretty much on schedule, or should we allow extra time for delays?
