San Francisco International (SFO) is the region’s primary international hub and usually handles the bulk of long‑haul and premium traffic, with United as a major carrier alongside several international and domestic airlines. The airport sits about 13 miles (≈21 km) south of downtown San Francisco; BART offers a direct link to the city in roughly 25–35 minutes for a moderate fare, while taxis or rideshares typically take 25–45 minutes depending on traffic and can cost substantially more. SFO generally provides extensive lounges, dining and transfer facilities, but can be busy during peak hours and parking or curbside waits may be costly. Oakland International (OAK) often functions as a budget‑friendly alternative serving many low‑cost and leisure carriers, so fares can be competitive for domestic travel. Located roughly 20 miles (≈32 km) east of downtown San Francisco across the Bay, OAK is reachable by a short airport shuttle connection to Coliseum BART station plus a BART ride to the city (combined 35–60 minutes), or by car over the Bay Bridge in 25–50 minutes depending on traffic. The airport is smaller and usually easier to navigate than the bigger hub, though it offers fewer direct international routes and can require extra time to cross into central San Francisco. San Jose Mineta (SJC) is positioned as the Silicon Valley and business‑travel airport, typically serving domestic and some seasonal international routes operated by a mix of legacy and low‑cost carriers. It lies about 48 miles (≈77 km) south of downtown San Francisco; driving via US‑101 usually takes around 45–90 minutes depending on congestion, while rail options (Caltrain to Diridon plus a short taxi/shuttle) can take about 60–120 minutes with lower combined fares. SJC can deliver convenience and competitive pricing for South Bay travelers, but it usually means a longer journey to central San Francisco compared with SFO or OAK.

Montréal–Trudeau (YUL) is the city’s main international hub, typically handling most long-haul and domestic traffic with national and global carriers such as Air Canada, Air Transat and WestJet alongside seasonal charters and low-cost options. Fares on major routes can be competitive but sometimes higher than small regional airports. The terminal sits roughly 20–25 km from downtown Montreal; taxis and rideshares usually take 20–35 minutes and can cost around CAD 35–55, while express buses or shuttles take about 40–60 minutes with fares typically in the low-double digits or comparable regional transit rates. Pros: wide amenities and frequent flights; cons: can be busy and subject to peak-hour delays.
