An airport connection, planned around the departure
STI is Santiago's airport, 75 km south of POP over the Cordillera Septentrional, and it handles a lot of the domestic, Caribbean and US routes that POP does not. People book this run when a flight out of STI is cheaper or better timed, when a cancelled POP departure is rebooked from Santiago, or simply because family lives in the Cibao. The drive itself is straightforward on the Autopista Duarte; the part that matters is the clock. Send the STI departure time and we work backwards — check-in window, the mountain grade where trucks slow everything down, and a buffer that is real. On the way back we do the reverse, meeting your STI arrival with a name sign in the terminal.
