Only 5% of the world's population has ever been on an airplane.

The claim that only 5% of the world's population has ever been on an airplane is supported by web evidence suggesting low global access to air travel. For instance, sources indicate that only a small fraction of the global population engages in air travel, with about 11% having used air transport in 2018 according to some estimates. Despite the growth of the aviation industry, access remains limited worldwide, supporting the claim's plausibility. However, due to the nature of such estimations and the lack of precise data, the claim can be considered as generally accurate but with some room for uncertainty.
