I see. There are a bit less amount of missions since the 2025 rollover bug as I heard, but it is also possible that your area doesn’t have any. You can expand your visible area by clicking on the airports and helipads and fast traveling to them. They will unlock a circle around them on the map. Nearby locations are cheap to travel to, so you can uncover a bit more area and see if you find any further. You can also try to close live weather in the settings - online before you start missions, so you have a clear weather to fly in, if you prefer.
