Sabiha Gokcen Airport (SAW) Flight Compensation: EU261 Guide for Istanbul's Asian Side Hub

When EU261 applies, the standard distance-based compensation tiers determine your entitlement:

These are per-passenger amounts. A family of four disrupted on a Wizz Air flight from SAW to London would claim €1,600 total — regardless of having purchased ultra-low-cost tickets.

Fog is the defining operational challenge at Sabiha Gokcen. Understanding the geographical and meteorological reasons behind SAW's fog problem is essential for evaluating whether an airline's extraordinary circumstance defence holds up.

Geography of the Fog Trap

Sabiha Gokcen sits at the western extremity of the Kocaeli basin — a broad, low-lying geographical depression that extends eastward along the southern shore of the Black Sea toward Izmit and beyond. The basin is bounded by low hills to the south and the Sea of Marmara coastline to the southwest, creating a natural bowl that traps cold, moist air at ground level.

During autumn and winter months (October through March), clear, calm nights allow the ground to radiate heat rapidly. As surface temperatures drop, moisture in the low-lying basin air condenses into dense radiation fog. Unlike coastal fog that can be dispersed by sea breezes, Kocaeli basin fog is trapped by the surrounding topography and can persist well into the late morning or even afternoon. On severe fog days, visibility at SAW can drop below 100 metres — far below the minimums required for even the most advanced instrument landing systems.

Frequency and Predictability

SAW experiences significant fog events on approximately 40 to 60 days per year, concentrated in the October-March winter half. This is roughly double the fog frequency at Istanbul Airport (IST) on the European side, which sits at higher elevation with better drainage and exposure to Bosphorus air currents. The contrast between the two Istanbul airports is stark: IST might operate normally while SAW is completely fog-bound just 50 kilometres away.

Claim impact: The Kocaeli basin fog pattern is one of the most thoroughly documented weather phenomena in Turkish aviation. SHGM publishes meteorological data, and every airline with SAW operations has access to decades of fog frequency statistics. Airlines operating winter schedules from Sabiha Gokcen know with near-certainty that fog will disrupt operations on dozens of days each season. Building adequate fog contingency into SAW schedules is a basic operational requirement, not a response to unpredictable events. Routine Kocaeli basin fog is foreseeable and does not constitute extraordinary circumstances under EU261. Only genuinely unprecedented fog of historically unusual duration or density might qualify — and even then, the airline must demonstrate that this specific event exceeded all reasonable forecasting.

When the Airline's Fog Defence Fails

Several factors consistently undermine an airline's attempt to cite fog as an extraordinary circumstance at SAW:

• Other airlines operated normally — If EU carriers continued departures during the same fog window, the defending airline's case collapses
• Fog lifted before the scheduled departure — If conditions improved but the airline still cancelled, the extraordinary circumstance defence is invalid
• Proactive cancellation without actual fog — Airlines sometimes cancel SAW flights based on fog forecasts that never materialise
• Inadequate schedule buffer — If the airline scheduled a tight turnaround knowing SAW's fog history, the resultant delay is an operational choice

For the substantial volume of SAW flights not covered by EU261 — primarily Pegasus domestic and non-EU international services — Turkey's SHY-Passenger regulation provides the applicable passenger rights framework.

Filing a Complaint with SHGM

The Sivil Havacilik Genel Mudurlugu (SHGM) accepts passenger complaints through its online portal. Passengers must file within a reasonable timeframe and provide booking details, evidence of the disruption, and a description of the loss suffered. SHGM investigates complaints and can impose fines on airlines that violate SHY-Passenger requirements.

SHY-Passenger Rights at SAW

Under SHY-Passenger, passengers at Sabiha Gokcen are entitled to:

• Care during delays: Meals, refreshments, and communication access after specified delay thresholds
• Overnight accommodation: Hotel and transport for delays requiring overnight stays
• Denied boarding compensation: Financial compensation when denied boarding due to overbooking
• Cancellation options: Choice of refund or re-routing when flights are cancelled

While the SHY-Passenger framework is less comprehensive than EU261 and the compensation amounts are generally lower, it provides meaningful protections for passengers on Pegasus and other Turkish carriers at SAW.

1. Determine EU261 eligibility — Was your flight operated by an EU-registered carrier departing SAW, or did it arrive from an EU airport? If yes, EU261 applies and Avioza can pursue your claim. If not, consider SHGM for SHY-Passenger protections.

2. Gather your documents — Booking confirmation, boarding pass, airline communications about the disruption, photographs of departure boards, and any expense receipts from the delay period.

3. Check eligibility with Avioza — Enter your flight details into our verification system. We confirm EU261 applicability, identify the airline's registration, calculate route distance, and verify actual delay duration.

4. Submit your claim — Complete the form with your personal details. Our team evaluates optimal jurisdiction and begins the process immediately.

5. We handle everything — From initial airline contact through escalation to the relevant national enforcement body or court. For SAW claims, our fog data verification and single-runway analysis provide decisive evidence against airline defences.

For EU-carrier flights from SAW, filing in the airline's home EU country often provides significantly more time and better enforcement infrastructure than Turkish courts.

• Kocaeli fog expertise — we maintain detailed SAW fog records and verify every weather defence against actual METAR visibility data from Sabiha Gokcen's own meteorological station
• Single-runway analysis — we document cascading delay patterns at SAW's single runway to prove that congestion-related disruptions are operational, not extraordinary
• Non-EU jurisdiction strategy — we identify the optimal country to file your claim, maximising both time limits and enforcement strength
• No win, no fee — zero financial risk to you throughout the entire process regardless of outcome
• Pegasus and budget carrier knowledge — deep expertise in the specific delay patterns and rejection tactics of SAW's dominant carriers
