Users of the Santa Monica Airport have filed a Part 16 Complaint due to excessive landing fees. In addition a lawsuit was also filed against the City of Santa Monica over the excessive landing fees.
Earlier the FAA ruled that the airport had to remain open through 2023. What is not clear to me is what happens after 2023. My guess is that there is a possibility they could close the 2000 ft of runway the city supposedly "owns" but not the whole airport.
