What is your home city/country? How long is the trip to post from there, with what connections? How easy/difficult is it to travel to this city/country?
We're from the New York area. A direct JFK-Lagos flight started not long into our time in Lagos, which was great for us; the flight itself is about ten hours. There's also an Atlanta flight that's a bit longer. The particular difficulty with flying into/out of Lagos is that even if, like us, you are lucky to not need any connecting flights in the US, the potential for traffic stretching what can be a 15 minute drive into a 4 hour one and the insanity of the airport means that you need to leave for your flight about six-eight hours before it's scheduled to take off. This also discourages the concept of quick weekend trips. Flying back into Lagos is better, though baggage claim can take a long time. - Jun 2019

USA- about 14 hours flight time, but much longer when you factor in connection times, and how early you have to leave for the airport because of traffic. Usually about 24 hours door-to-door. - Mar 2018
