Busan is served by two main airports: Gimhae International (PUS) and the smaller Seokpo Domestic airfields for limited flights. Gimhae usually acts as the international and regional gateway, handling full-service carriers and low-cost airlines alike, so fares can range from budget-friendly to premium depending on carrier and season. The airport sits about 20–25 km west of central Busan; the metro’s Sasang line or Airport Railroad typically takes 40–50 minutes, taxis about 30–45 minutes depending on traffic with fares commonly higher than public transit. Pros: wide choice of airlines, regular international routes and convenient rail links. Cons: can be busy at peak times and transfer to some southern districts may require longer travel.
