Yaounde is extremely disorganised and dysfunctional. It's hot and humid and there is no A/C. Upon arrival all flights exit through one security area. At this point a lady from the Ministry of Health stops random passengers checking their Yellow Fever certificate. At the customs desk lines form for visa stamps this is extremely slow. Getting baggage out of the airport is also chaos as airport staff want to check baggage tags against passenger. Again not everyone is stopped. I wouldn't recommend a taxi there are a lot of touts. Departure is equally frustrating no clear signage so always confusion. Need to pay a departure tax. Then you go to a window in the departure hall and give the CFA to a woman who will stamp your ticket. After this you need to fill out a departure form and have your passport stamped. Once you arrive at your gate your hand-carry luggage is hand checked as are you. Then you can proceed to your flight. There are no announcements so make sure you know where you're going! Not the worst airport I've been to but difficult all the same.
