In short, there aren’t any — at least from my research when trying to find a ticket out of Accra near the end of November. So if you manage to make it into Ghana, make sure that you budget a fair amount ($1,000+) for a plane ticket out of Accra – it likely won’t be cheap unless you know peeps in the travel industry that can get you discounted airfare. Based on my research, it’ll cost you upwards of $1,000 to get anywhere from Accra – whether that be Nairobi, Madrid, or Washington DC doesn’t much matter.
United has a non stop route to Washington DC, which is likely to be your best option for those flying to the states. The other cheapest flights I saw seem to be through Cairo or Istanbul.
