When we recommend leaving Moca
We recommend a pickup 2.5 hours before your flight from Moca. The road into Santiago is straightforward, but it does pass through town traffic before joining the faster stretch toward the airport, and that is where a few extra minutes can disappear. STI itself is quick to clear once you arrive, so the buffer is mostly about the drive and a comfortable margin at check-in, not a long airport process. Add 20–30 minutes if you are travelling on a market day or in a larger group.
