20–25 minutes by bus puts you at COASTER’s Santa Fe Depot stop
From Terminals 1 and 2, city bus route 992 runs every 15–30 minutes and gets you from the airport to Santa Fe Depot in about 10–15 minutes, depending on traffic on N Harbor Drive. The COASTER commuter rail to North County (Oceanside, Carlsbad, Encinitas, Solana Beach, Sorrento Valley) leaves from Santa Fe Depot’s track level, usually starting shortly after 5:00 a.m. on weekdays and running until around 10:30 p.m., with fewer trains on weekends.
The COASTER is operated by NCTD, runs roughly every 30–60 minutes at peak times, and takes about 65 minutes end‑to‑end between Santa Fe Depot and Oceanside Transit Center. Fares use the PRONTO system: a one‑way Santa Fe Depot–Oceanside ride is typically in the $6–$7 range, and shorter trips like Santa Fe Depot–Solana Beach are a bit less. You can buy PRONTO value in the PRONTO app, at vending machines in some stations, or from retail locations in central San Diego.
From the airport, follow signs for “Public Transit” outside Terminal 1 or Terminal 2; both terminals have clearly marked bus stops served by route 992. The 992 is a standard MTS city bus with luggage racks and uses the same PRONTO payment as the COASTER, so a 2‑hour PRONTO fare window lets you transfer from the bus to the train without paying twice. Santa Fe Depot itself sits about 2.5 miles southeast of the airport, a straight shot along the bay.
COASTER trains have specific departure times, not metro‑style headways, so check the NCTD schedule before you leave the terminal; missing a train can mean a 30–60 minute wait, especially evenings and mid‑day. Trains typically use Tracks 3 and 4 at Santa Fe Depot, with electronic boards listing “COASTER” and the train number alongside times for Amtrak Pacific Surfliner. Typical ride times: about 35 minutes Santa Fe Depot–Carlsbad Village, around 30 minutes to Encinitas, and roughly 25 minutes to Solana Beach.
One practical tip: build at least a 30‑minute buffer between your scheduled COASTER departure and your planned airport arrival time at Santa Fe Depot, especially if your flight lands during the afternoon rush between 3:00 p.m. and 6:00 p.m. That covers a late bag drop from Terminal 2, a 15‑minute wait for the 992, and a slow run down Harbor Drive without forcing you into a rideshare at the last minute.
