Departure tax is included in the price of a ticket.
Addis Ababa’s Bole International Airport is Ethiopia's only international airport. Although modern, there’s little more than a 24-hour bank, a restaurant and a few cafes in arrivals; baggage carts and wi-fi are free. There’s a bar and duty-free shops in departures.
Ethiopia’s only international and national carrier, Ethiopian Airlines is rated as one of the best (and largest) airlines in Africa, with a modern fleet and a good safety record.
One thing to watch out for: if you want to fly with a European airline such as Luthansa or KLM, double-check that you will actually be on one of their planes and not on an Ethiopian Airlines plane. They route share and commonly bundle their passengers onto Ethiopian Airlines and then kindly charge you more than you’d have paid if you’d bought directly with Ethiopian Airlines.
For Ethiopia, flights during the month of August, over Easter, Christmas and New Year should be booked well in advance. Ethiopians living abroad tend to visit their families during this time, and tour groups often try to coincide with the major festivals. Ticket prices are highest during this period.
