Again, this is not a real problem. Here's the data on domestic flights (far less than international flights) in Nigeria from the Nigerian Bureau of Statistics for 2020 and 2021. Barely 5% of the total population on aggregate and doesn't count individual passengers. https://nigerianstat.gov.ng/elibrary/read/1241160#:~:text=Executive%20Summary,compared%20to%204%2C870%2C072%20in%202020.

To add to this, here's data showing air traffic measured by passenger-kilometres from 2008 to 2021. What's noticeable here is the drastic decline in flights to and from Nigeria. Nigerians are simply not travelling anywhere. https://x.com/filleduchaos/status/1749355565912936644?s=20
