This study evaluates the resilience of Pulkovo Airport and its renovation project in the face of international sanctions, comparing their effects with the preceding COVID-19 pandemic. Through cost-benefit and sensitivity analyses, we assess how pandemicrelated restrictions and sanctions in format of border closures influenced the project's profitability and the social benefits generated by the airport. The social impact was evaluated using theories of Efficient Time Allocation and the Generalized Cost of Traveling, given that the airport renovation under the concession agreement led to a reduction in the time passengers spent in terminals. The research methodology includes calculations for cargo handling by the airport. The findings reveal that, by the end of 2023, the pandemic and sanctions negatively affected airport operations, including reductions in passenger traffic, takeoff and landing operations, cargo handling, Social Net Present Values (NPV), and overall social impact. However, the impact of sanctions was not as severe as that of the pandemic, both in absolute and relative terms. Specifically, the airport’s NPV declined by 3.03 times due to the pandemic, with the benefit-cost ratio falling from 3.91 to 2.42. Nonetheless, the effect of sanctions was less severe, reducing the NPV by 1.29 times compared to the pandemic scenario alone, resulting in a benefit-cost ratio of 1.96. However, the renovation project was particularly affected by the sanctions, as its NPV turned negative. Despite these challenges, the airport demonstrated resilience, with pandemic adaptations mitigating the sanctions' impact on overall performance. The project's social benefits remained largely intact, underscoring its critical role in creating public goods. Additionally, key parameters influencing the project's performance were identified, highlighting areas for strategic focus in future infrastructure initiatives.
