Sao Tome is served by 4 airlines. TAP flies from Lisbon twice a week. The Sunday flight also stops in Cape Verde. Angolan Airlines flies once a week with a stop in Cabinda. Four times a week Air Gabon and Air Sao Tome e Principe fly between Sao Tome and Libreville. Also four flights a week are going to Principe.
There is a car rental company 200 meters from Mistral voyage towards the airport.
The international airport tax is always US$20 or 20 euro plus a 2% service charge. This creates a lot of problems for the poor airport staff who don’t know in which currency they must collect the service charge or how to give change. So keep 3700 dobras to pay with which seems to be the only solution.
