Can you travel from nigeria to Ghana without a passport on plane?

It is not possible to travel from Nigeria to Ghana without a passport. Both Nigeria and Ghana are members of the Economic Community of West African States (ECOWAS), which allows for free movement of people between member countries. However, a valid passport is still required for travel between ECOWAS countries. The only exception to this rule is for travel between Nigeria and Benin, where a national ID card is accepted instead of a passport.
