Oslo Airport (OSL) at Gardermoen is Norway’s primary international gateway and typically serves as the city’s full-service hub, handling long-haul and European carriers alongside national airline operations. It’s about 50 km northeast of the city center, with express trains to Oslo Central Station in roughly 20–25 minutes and regional trains or Airport Express (Flytoget) fares usually higher than local trains; public trains take about 20–30 minutes with lower ticket prices. Coaches and taxis take around 40–60 minutes depending on traffic, with taxis costing substantially more. Pros: modern terminals, wide airline choice and reliable train connections. Cons: distance from downtown and occasional higher taxi fares. Sandefjord/Torp Airport (TRF) is typically positioned as a low-cost alternative used by budget carriers and leisure flyers, serving southwest of Oslo and nearby regions. It sits roughly 110 km from Oslo proper, with shuttle buses to the city taking around 1 hour 30 minutes to 2 hours depending on traffic and usually offering the most economical ground option; trains are not direct and can add complexity. Taxis are available for door-to-door convenience but can be costly for the distance. Pros: often cheaper fares and simpler low-cost operations. Cons: significantly farther from central Oslo and longer transfer times.

Istanbul Airport (IST) serves as the city’s main international hub and is typically the first choice for long-haul and premium carriers, while also handling many regional flights. Located about 40–50 km northwest of the historic center, travel times can range from 35–70 minutes by taxi depending on traffic; the metro and Havaist shuttle buses offer regular connections in roughly 45–70 minutes, with fares usually in the moderate range for airport services. The facility is modern and spacious, well suited for transfers and full-service amenities, though distances between gates can be long and peak-hour surface travel may feel slow. Sabiha Gökçen International Airport (SAW) usually functions as Istanbul’s secondary airport and can be more budget- and low-cost-carrier oriented, hosting many regional and European flights. It sits on the Asian side about 35–45 km from central Sultanahmet, with travel to downtown typically taking 45–75 minutes by taxi or shuttle; public buses and Havatas/Havaist services run frequently, and fares are generally lower than premium express options. The airport is often perceived as more compact and easier to navigate than the main hub, but transfers between continents require extra time and logistics for passengers crossing the Bosphorus.

The cost of a one-way flight from Oslo to Istanbul ranges from $83 (November 2026) to $140 (March 2027). On average, the ticket price is about $109–$212.
